You made this video in February and there were 19 games in the profile for rebar support. 6 months later and there are now 20. Way to go Nvidia, you managed to add one game to the list of supported titles in 6 months!
I've stuck with nvidia this gen but their anti consumer bullshit sickens me. They only care about supporting products that are in the spotlight, once the next gen comes out, the one before is all but forgotten about. I might go AMD next gen since they've been very impressive this gen. Just need to improve their RT and upscaling methods, and nvidia will be in trouble.
It's really odd cause I activated it and am getting alot of pop in and graphical glitches. Turned it off and the issues is fixed. Really odd. I have a 5800x 3080 Strix 970 Samsung M.2 So I shouldn't be having any of these issues.
AMD initially added it as a marketing push to just sell more CPUs and GPUS (hence why they initially claimed you needed a newer Ryzen config) but they actually supported it. Nvidia just added it to counter that marketing point and hasn't added a single game to the supported list since launch.
ReBar is definitely more useful in improving 1% lows than average fps. In my opinion, the 1% lows have a much bigger impact on my experience than having a little extra overhead does.
@@Ladiozmight be really late to reply this, but you better check if its really enabled by running gpu z and see if its enabled and check the BAR1 by pressing the status, if its the same as your VRAM then it is enabled, and you also better open nvidia inspector to enable it in all games
@@bil6814 Yes you are late, infact so late that I got rid of my 3060 TI and bought another card. The 3060 TI uses too much power and barely any performance. Terrible card from Nvidia.

Me too.. When I had the 2080Ti I was bummed that they did not made support for the 2000 series even though my mainboard could support RESIZE BAR. Now that I got the 4090 and all is supported.... Its not even an option to enable from Nvidia without some kind of driver hack! (Nvidia Inspector) ... And then the results are so weak and disappointing! We are talking 0-2 fps at best .. haha..

This in particular 4K Ultra which I play. Its a scam and basically useless tools.
That is hard to hear. I think it sucks since its giving free FPS and cost 5 min of settings in bios... Tbh since i went to a 6950 xt first time AMD, i cant understand why Nvidia is such prefered over amd. I think Nvidia needs to do a lot to get me back on any of their GPU since the performance to price is not really great anymore (as it was like for 1080 ti). Hope they get back to reality soon.
@@redknight2120 You are right, and it annoys me that there are no competition. My son is up for a new GFX. And I think im gonna go AMD this time. But they are also very expensive not! :(
So it's actually completely worthless in any other game anyways? I currently struggle to get it enabled on my ASUS ROG Strix B550-A Gaming, 5800X and Asus/Noctua 3070 combo. Set all the respective BIOS settings and GPU-Z returns all things yes except for ReBAR enabled in BIOS, which I do have though. Also tried switching the GPU BIOS as I heard it would only work on Performance BIOS and I was running Quiet previously. No change. There are no BIOS updates available for either the Mobo or the graphics card... So if this all was in vein anyways, I could just stop trying.
until I saw this video I was under the impression that I have rebar working for everything. did not know this is dependant on game profiles. I activated it with nvidia profile inspector like you showed which gave me 67 fps compared to 62 fps with default profile setting (3080 ti FE, 4K everything maxed out on FH5 (8x MSAA and "extreme" where available), which is 10 % more fps, awesome
It doesn't rely on profiles at all. The only thing the graphics cards drivers needs to allow is being able to quickly check what it's in memory, and if it needs to be used yet. Thats it. The bigger issue is the fucking awful coding optimizations companies do. A trend that needs to stop. Where you'd probably find this helps? The ultimate graphics card melting experience? Either Minecraft or WoW raiding especially 25 man. Any card that can't meet those BARs is just bad. I bet with something like DBD, WoW in a Raid, and the CODs of the world would get benefit from the BAR. To really make you want to break someone? look up asynchronous circuitry history. and the History of Asynchronous memory. it's vile that the we need high clockspeeds. insane driver stunts. just for fucking awful code practices but Aysncronous circuitry being better used, or used at all is a big step forward in computing.Because while the driver is in rBAR mode, in theory what's not in instant need right now could be put to the side in a lower priority cache. In theory anyway.

They should honestly add this as a stock option/flag in the standard nvidia control panel for those with rebar enabled. Why they did it this way baffles me.
Resizable bar makes sense from a computer science perspective, it's about getting rid of the last bit of 32-bit era bottlenecks. Like the move to 64-bit, results won't necessarily be immediately apparent, but it's a necessary step in the long term. I got a Geforce 1650 Super, so no resizable bar at the moment . My lowly motherboard, an Asus AM320, however, does support it with a recent BIOS update. Which is genuinely impressive since this motherboard only cost 50 dollars when I bought it.
This kind of thing shows an unfortunate shift in nvidia's attitude towards user choice. In the past they would have added a setting to the control panel, and have it enabled or disabled by default based on profiles. Now you have to jump through all these hoops just to configure your own GPU, it's just indicative of the general shift away from right to ownership, you aren't trusted with control panel settings yourself.
Likely that RDNA 2 architecture was optimised to use SAM/ReBar, whereas Nvidia's Ampere architecture is not. Nvidia was sort of caught with their pants down and are scrambling to implement something after the fact.
Maybe that makes a difference on some systems but I'd have to be right on the edge of unplayable to risk system stability for that. Last time I updated my vbios, my Hardware Reserved system memory shot up to 32 GIGS! I just restarted with one stick to go to single channel and then put everything in and it was fine. But it was scary. I was afraid and alone. Totally needed a cookie afterwords.
Thank you man! I just got a 3060ti couple months ago and since it's an LHR model I didn't need to update it's Vbios thankfully so I just turned R-BAR through BIOS. I did what you showed on Call Of Duty Warzone and got +5-10 fps on the training map. I'll check it out on BF1 next since I already know it helps negate some bottleneck issues on BF:V and they run on the same engine. for those wondering I have a r5 5600x and 3200 cl16 memory
Interesting! Will test later. Always wondered why AMD had such a huge lead on R-bar, infinity cache and faster ram on lower end models can't explain all.
About nvidia's drivers not seeming to benefit from reBAR as much as AMD's counterparts; both have had their own ways to address system memory for caching and catching vram allocation issues.. Could be reBAR simply doesn't add much to whatever methods nvidia was already using, or that AMD's whole infinity fabric-approach naturally lends itself to adding more performance. As a random guy about to receive his own 3060Ti in a couple hours; can't wait to test this out on some Unreal Engine 5 demos!
Hey Daniel, there is music playing in the beginning segment of the video (Bring me the Horizon - Tear drops). I hope your video doesn't get flagged. Just thought I would let you know.
i tried few games on 3060 ti and i didn't saw any change in performance but there was a change in vram and ram usage. I tried rise of the tomb raider, shadow of the tomb raider, witcher 3, doom 2016, dying lighht, ghostrunner. I'm kinda dissapointed. Im not sure if im correct but it feels like doom 2016 loaded slightly faster and that's it
I've a 6950xt Reference card and when I enabled this through Bios, then Adrenaline.. it was a night and day difference.. The GPU in general is insanely powerful but my GPU temps went from (GPU Temp 68c // GPU Hotspot 88c) to (GPU Temp 72c // GPU Hotspot 110-115c) With REBAR/AMD SAM.. The quality was outstanding and I wasn't experiencing any kind of issues in the game, just that hotspot temp going to high for comfort.
as mine msi rtx 3090 suprim X. Both had huge power limit. I undervolted to 0.806v and 1740mhz gpu - Metro Exodus benchmark 100x run in a row stable, overclocked in msi afterburner memory +1000mhz. and it helped. Mine card is no silicon lottery winner; you can achieve on same 0.8v undervolt rougly in Metro Exodus stable around 1800mhz . Good luck ;) Plus I am waiting side panel modded with cutted holes for mine bad airflow NZXT h510i case , can drop further 3degrees temps down or more.
Hey Daniel, I just found out about NIS. It could be me, but I feel like this is a feature often overlooked, but for games with out DLSS, its a pretty option. I use it for Valhalla and Warhammer 3, where it runs at 85% of 4k, and upscales the image
Unrelated, I am loving my 6600 XT more and more. Before SAM, performance was better than a 3060. With SAM, its close to a 3060 Ti / 3070. Id love to see more of your 6600 videos!!!
@@emma6648 I’m sorry, who are you? Show some respect, Emma. That attitude aint gonna get you far in life, or bring happiness, no matter how smart you think you are.
@@fxspec06 Well depends on game, some games does support some dont. Also it depends if rtx had dlss enabled or disabled because dlss is by far the best thing for fps improvement and with that it goes over amd.
I've personally had both and it depends. I settled on the 6800xt for my 2560x1080 monitor and with custom settings on cyberpunk I can do rt reflections and psycho ssr and still get 60fps with fsr so it's good enough for that in my opinion and the extra vram could be useful down the line too but that's something we will have to observe in the future
@@pcgamingpurist I just haven’t found Ray tracing to be that rewarding visually when it tanks FPS. I play at 4k so I’m already demanding quite a bit out of a card. Sure NVIDIAs cards are better at ray tracing but there’s still a massive performance loss.
@@marshallgolowenski7439 The third generation of RT cores for Nvidia is supposed to have less performance hit when enabling Ray Tracing. Ray Tracing is farely new at this point in the gaming industry. Give it couple more years and it will be less demanding (better hardware) and more mainstream. I've seen comparison RT ON vs RT OFF in Dying Light 2 and the difference is stunning in my opinion.
Pretty sure you're not interested in Microsoft FlightSimulator, yet with it's basically unlimited scalability it should be the most demanding game on hardware and as that good for testing. Microsoft/Asobo are running a 10 year plan, in which they want to increase the graphics more and more, the endgame here imo is Photorealism on Desktop and VR. With scientific projects they given to highschools and the application of realworld physics maybe a possibility to show of math's to some extent. Even nowadays you could easily bring a 3080 to it's knees... what isn't the target of course but it shows the demanding nature of the title, as it should be already quite optimized. In this year they are switching to DX12 which should ease the huge CPU demands (photogrametry) and weed out the last bit of old coding left from ancient FSX, should then be even more interesting for you. Maybe great as a longterm project, to review the changes of hardware and revisit the state of photorealistic games. Thanks 💙
I have a water cooled 3090, and running Flight Sim 2020 at 4K maxed out graphics, I still get about 52fps average, and my GPU is going off at 99% the entire time
I just got a 3080 for my workstation PC and moved my 6900 XT to my HTPC. I don't play games on my workstation PC much besides multiplayer FPS games with my friends so this is handy
I believe that because AMD's Smart Access Memory only works with AMD processors, they are able to fully utilize the cpu-gpu combo because they make it all.
Again get content nicely rounded up. It beggars belief why Nvidia uses such a convoluted manner addressing Resizeable bar whereas SAM works from the bios out of the gate. It's Nvidia just being awkward and anti consumer imho ..
While this may work for some people in some games it completely made Rust not even launchable at all. Crashed before getting into the game. Then I couldn’t even CTRL + ALT + DELETE to restart or restart otherwise. Just FYI beware.
Amd has a hardware memory scheduler and Nvidia uses a software scheduler this puts a driver overhead on the processor, the problem is that for AMD that scheduler only works properly in direct x 12 or Vulkan in older API's don't work ass it should. that's why AMD resizable bar works best, Nvidia has a driver overhead.
both have hardware scheduler since turing and navi, you got your information wrong, and second resizable bar has literally nothing to do with "scheduling", its about reading from system memory in larger chunks...
Question: I have a 6750XT and a 12100F Should I enable Resizable BAR???? Cause I've seen that some games actually perform worse using resizable bar while combining an intel cpu with an amd gpu
It is good for some games for example battlefield 5 but it has its downsides. In my particular case for some reason it doesn't like when I do some idle mining with rebar on. At some point it just hard bricks my pc which gives one long and three short beeps after which I have to reset CMOS. The other thing is that, when I watch RUclips no matter if I use Edge or Firefox my computer just randomly restarts. It never happens while gaming tho so it's not too bad. Ryzen 5800x, 3080ti, x570 tuf gaming plus.
So the card that you have is the eagle 12g version? I just got the same one but I find no reviews anywhere for this 12g skue. Reason I'm asking is because my temps get to 71 to 75 at 1440p. Not too bad but fans are loud. Yours is running at 65. Thanks you
@@danielowentech I'm just lucky I was able to get a 3080 12g at microcenter last Thursday. I got there at 10 and was only two of them available at 1250 and I told my self that if someone gets it then I'm not buying in or the 1600 dollar one as they are expensive. Luckily I saw one guy get the one and i guarded their display case until they attended me and got it. God I felt so happy. It's the first high end card Ive ever gotten
well I could activate above 4G decoding and resizable Bar in the UEFI (Gigabyte X570 Aorus Elite) but still can't use rBar because I have a RTX 2080 Super and NGreedia doesn't care abour rBar much, nor on backwards compatibility.
I have the same mobo (X570 Aorus Elite). So far got it working only on F32 bios. F36 and F37a (beta) not working, even if the option is available in bios to turn on. Did not try any bios in between.
How do you get this to even work; even after hitting the magnifying glass on profile inspector there is no ReBar option. 3080 supports it. It's enabled in Bios. MSI control center says its enabled... :(
Hey i need help for my building pc, i still confuses between amd and nvidia in term of for streaming and recording, mainly i use davinci resolve for editing, i got budget limit about 1000-1200$ i confused between rx 6600 or rtx 3060, the rtx price is around 630$ in my country and amd about 514$.Thank you in advance
When it comes to recording/streaming, Nvidia has better compression, so when streaming it needs slower internet speed and when recording, the video files will be smaller. By how much, I don't know. There might be some youtube video analyzing that. Quality of the video should be roughly the same though. Even though I'm generally on AMD side, If you can fit it in your budget I think RTX 3060 is a good choice, but if you want to save money, RX 6600 is perfectly good option too.
Huge thanks for this video 👍 I have been on the fence whether to use rebar or not . It appears to help with fps boost so I'm in 😁 but come on Nvidia 😒 this needs to be supported for more (ALL) games ! I look forward to your future videos ! Liked and subbed 👍
I don't know what is wrong with metro exodus enhanced editon but i lose a lot fps even tho the game is on nvidia's whitelist. On average i lose 20fps. I have all the required pc parts and it shouldn't worsen my perfomance but rather improve it
100x Thanks :) already few frames more in Kena Bridge of Spirits, DOOM Eternal, Bright Memory Infinite . No difference in Crysis Remastered, God of War, Far Cry New Dawn.
I have a RTX 3060 and have it pre installed on it (REBAR), I enabled it and downloaded nvidia profile inspector. Well I don't have the profiles mentioned. It only shows BE and BF, no BA, BB. Is there something else I would need to do or am I SOL?
Did you find it? It's no longer under Unknown settings. Nvidia now has it under "Common" settings. They are now labeled as rBAR Feature, rBAR Options and rBAR Size Limit.
I've been trying to enable resize bar in the bios but the windows wont boot then, it just keeps going back to the bios until I reset the changes... updated my mobo Gigabyte B550M Aorus Elite too, I guess its my 3060Ti vbios... and idk how to do that.
Running a game with reBAR off should not cause the issue in RDR2 (and it didn't in any other game, nor on my 6800xt in the same PC). Seems more like a driver issue or something, although it's not obvious why reBAR on would solve it.
A nice video, thank you! Has anyone tried to enable those 0x000F00BA, 0x000F00BB and 0x000F00FF in a global driver profile? So that they are always in use everywhere... 😁
@@addictedtoRS Yes, but I didn't notice any difference but I think when doing compute on GPU and there is DMA between CPU/GPU/RAM the resizable BAR can lead to problems or huge performance penalty. Like BAR is 16GB and GPU compute wants access something at 24GB in DDR ram. Then the iommu must rise an exception, move the MMU window then the GPU can access. This brings a lot of latency. Reducing/resize BAR OTOH can lead that the GPU address space fits better into CPU address space, so less iommu tlb translation = less latency. If the bar is super small it might fit into a single iommu region, then it's as fast as without iommu at all.
I only wish NVIDIA allows ReBAR for RTX 2000 series. Even with a vBIOS mod. But no, they had to lock everything down and encrypt the vBIOS ! Because they are NVIDIA !
Nvidia's way has a pro. The half of the game that loses fps will not be using it. But they could just give a toggle to enable for all. Nvidia way's biggest downside is that they cannot go verify dozens fo games every month so games get left out. Personally i don't care as i have a Z390 board so i can't use it reliably anyway.
@@Darkhalo314 Mo board (msi pro gaming AC) had a beta biod for it which they pulled lateron. Bummer as it was a 240 euro board... guess i will have to wait for it till 2024 when i plan to upgrade.

Surely you know that AMD had had to pull all kinds of tricks due to their GPUs having a smaller bus width, slower vram speed and so it's working with less bandwidth plus data packet speeds are transferring slower. Of course you know. Infinity Cache, you know, why it's there. It stands the reason, without even straining, that carrying larger data packets at once can be beneficial when you're limited on speed and bandwidth. If it's not clear then let me try to visualize this. Imagine the bus with as a highway with only 4 lanes, imagine semi trucks carrying the 256 MB packets and they're limited at 55mph. Imagine that data needed doesn't break always fit perfectly in the 256chunks so there will be trucks having to carry the rest of a shipment that would not fit on a single truck. If the truck carrying the rest of a shipment was able to utilize the other half of it's empty space, you we'll have to sort and separate on the other end. The Nvidia highway is wider and the trucks can go faster, by design it can afford to send a partial load. Once the data gets through the highway (bus) to the memory, is able to move around faster because Gddr6x

Likely that RDNA 2 architecture was optimised to use SAM/ReBar, whereas Nvidia's Ampere architecture is not. Nvidia was sort of caught with their pants down and are scrambling to implement something after the fact.
Thanks for the video. It works well. Now pushing 98 fps with Forza Horizon 5 bench at 4k ultra with my 3080 10gb +100mhz.
Maybe that makes a difference on some systems but I'd have to be right on the edge of unplayable to risk system stability for that. Last time I updated my vbios, my Hardware Reserved system memory shot up to 32 GIGS! I just restarted with one stick to go to single channel and then put everything in and it was fine. But it was scary. I was afraid and alone. Totally needed a cookie afterwords.
The inspector bit is almost exactly what we had to do back in the day to get proper SLI support when a game launched
Wow, youre the man!!
This really works, just gained 15 fps in 4K...How??
Thank you man! I just got a 3060ti couple months ago and since it's an LHR model I didn't need to update it's Vbios thankfully so I just turned R-BAR through BIOS. I did what you showed on Call Of Duty Warzone and got +5-10 fps on the training map. I'll check it out on BF1 next since I already know it helps negate some bottleneck issues on BF:V and they run on the same engine. for those wondering I have a r5 5600x and 3200 cl16 memory
warzone started bugging with resizable bar
Biggest thing with battlefield 1 is to turn dx12 off. It is horribly optimized. You are much better off with dx11 in that game.
Interesting! Will test later. Always wondered why AMD had such a huge lead on R-bar, infinity cache and faster ram on lower end models can't explain all.
About nvidia's drivers not seeming to benefit from reBAR as much as AMD's counterparts; both have had their own ways to address system memory for caching and catching vram allocation issues..
Could be reBAR simply doesn't add much to whatever methods nvidia was already using, or that AMD's whole infinity fabric-approach naturally lends itself to adding more performance.
As a random guy about to receive his own 3060Ti in a couple hours; can't wait to test this out on some Unreal Engine 5 demos!
Hey Daniel, there is music playing in the beginning segment of the video (Bring me the Horizon - Tear drops). I hope your video doesn't get flagged. Just thought I would let you know.
i tried few games on 3060 ti and i didn't saw any change in performance but there was a change in vram and ram usage. I tried rise of the tomb raider, shadow of the tomb raider, witcher 3, doom 2016, dying lighht, ghostrunner. I'm kinda dissapointed. Im not sure if im correct but it feels like doom 2016 loaded slightly faster and that's it
SAM might be better coz of architecture with infinity cache and lower memory bandwidth, and i think its a major reason for that fps bump
I've a 6950xt Reference card and when I enabled this through Bios, then Adrenaline.. it was a night and day difference.. The GPU in general is insanely powerful but my GPU temps went from (GPU Temp 68c // GPU Hotspot 88c) to (GPU Temp 72c // GPU Hotspot 110-115c) With REBAR/AMD SAM.. The quality was outstanding and I wasn't experiencing any kind of issues in the game, just that hotspot temp going to high for comfort.
wow looking at these benchmarks makes me realize my 3080 ti is running much hotter its hitting 86c not sure why but its a 3080ti ftw 3
as mine msi rtx 3090 suprim X. Both had huge power limit. I undervolted to 0.806v and 1740mhz gpu - Metro Exodus benchmark 100x run in a row stable, overclocked in msi afterburner memory +1000mhz. and it helped. Mine card is no silicon lottery winner; you can achieve on same 0.8v undervolt rougly in Metro Exodus stable around 1800mhz . Good luck ;) Plus I am waiting side panel modded with cutted holes for mine bad airflow NZXT h510i case , can drop further 3degrees temps down or more.
Hey Daniel, I just found out about NIS. It could be me, but I feel like this is a feature often overlooked, but for games with out DLSS, its a pretty option. I use it for Valhalla and Warhammer 3, where it runs at 85% of 4k, and upscales the image
Thank you so much for this video dude. I was kinda scared to use but now I'm so happy I did XD
Goob job! great stuff :). Would be nice if their is any different betweeen AMD & Intel CPUs with Nvidia and AMD GPU.
Hi Daniel, how does this look today ? Has this improved? Should I turn it on on my 3060 Ti?
Unrelated, I am loving my 6600 XT more and more. Before SAM, performance was better than a 3060. With SAM, its close to a 3060 Ti / 3070. Id love to see more of your 6600 videos!!!

@@fxspec06 Well depends on game, some games does support some dont. Also it depends if rtx had dlss enabled or disabled because dlss is by far the best thing for fps improvement and with that it goes over amd.
Thanks a lot! I didn't know that nvidia doesn't enable rebar on all games, it should be like amd or at least include it in the experience app
Which card do you like more? The 3080 or your 6800xt?
I sold my 3080 and bought a 6900xt and couldn’t have been happier.
I'll do a video on it after more testing
I've personally had both and it depends. I settled on the 6800xt for my 2560x1080 monitor and with custom settings on cyberpunk I can do rt reflections and psycho ssr and still get 60fps with fsr so it's good enough for that in my opinion and the extra vram could be useful down the line too but that's something we will have to observe in the future
@@pcgamingpurist I just haven’t found Ray tracing to be that rewarding visually when it tanks FPS. I play at 4k so I’m already demanding quite a bit out of a card. Sure NVIDIAs cards are better at ray tracing but there’s still a massive performance loss.
@@marshallgolowenski7439 The third generation of RT cores for Nvidia is supposed to have less performance hit when enabling Ray Tracing. Ray Tracing is farely new at this point in the gaming industry. Give it couple more years and it will be less demanding (better hardware) and more mainstream. I've seen comparison RT ON vs RT OFF in Dying Light 2 and the difference is stunning in my opinion.
Pretty sure you're not interested in Microsoft FlightSimulator, yet with it's basically unlimited scalability it should be the most demanding game on hardware and as that good for testing.
Microsoft/Asobo are running a 10 year plan, in which they want to increase the graphics more and more, the endgame here imo is Photorealism on Desktop and VR. With scientific projects they given to highschools and the application of realworld physics maybe a possibility to show of math's to some extent. Even nowadays you could easily bring a 3080 to it's knees... what isn't the target of course but it shows the demanding nature of the title, as it should be already quite optimized.
In this year they are switching to DX12 which should ease the huge CPU demands (photogrametry) and weed out the last bit of old coding left from ancient FSX, should then be even more interesting for you. Maybe great as a longterm project, to review the changes of hardware and revisit the state of photorealistic games. Thanks 💙
I have a water cooled 3090, and running Flight Sim 2020 at 4K maxed out graphics, I still get about 52fps average, and my GPU is going off at 99% the entire time
does intel haswell CPUs support resizable bar? I use old 10 core xeon and I want to switch to rtx 3060 from gtx 1060
I just got a 3080 for my workstation PC and moved my 6900 XT to my HTPC. I don't play games on my workstation PC much besides multiplayer FPS games with my friends so this is handy
I believe that because AMD's Smart Access Memory only works with AMD processors, they are able to fully utilize the cpu-gpu combo because they make it all.
Again get content nicely rounded up. It beggars belief why Nvidia uses such a convoluted manner addressing Resizeable bar whereas SAM works from the bios out of the gate. It's Nvidia just being awkward and anti consumer imho ..
6800XT is very competitive against 3080 12gb. Im surprised.
6800 XT trades blows with the RTX3090 @ 1080p/1440p ... Not surprising at all.
Yep it's essentially a 6900 XT with some missing cores
Its also a good heater for the winter!
hmn I want to try this but my Nvidia Profile Inspector don't show 0x000F00BA option at all
Make sure you clicked "show unknown" on the top right.
why white backgrounds? my eyes.
While this may work for some people in some games it completely made Rust not even launchable at all. Crashed before getting into the game.
Then I couldn’t even CTRL + ALT + DELETE to restart or restart otherwise. Just FYI beware.
Interested in trying out testing some VR games with s.a.m.
Amd has a hardware memory scheduler and Nvidia uses a software scheduler this puts a driver overhead on the processor, the problem is that for AMD that scheduler only works properly in direct x 12 or Vulkan in older API's don't work ass it should. that's why AMD resizable bar works best, Nvidia has a driver overhead.
both have hardware scheduler since turing and navi, you got your information wrong, and second resizable bar has literally nothing to do with "scheduling", its about reading from system memory in larger chunks...
Daniel Owen! you the new LINUS. Thank you so much for the added fps!
Question:
I have a 6750XT and a 12100F
Should I enable Resizable BAR????
Cause I've seen that some games actually perform worse using resizable bar while combining an intel cpu with an amd gpu
Rebar has basically been abandoned, the crappy thing is it’s a great feature that works
You just reminded me to update BIOS on my B450M Mortar MAX. Thanks.
How can i see in the game where i forced Resizeable BAR if it is realy working?
After updating the program, the code has changed. Can you post another clip?
Do you have older gen Ryzen CPUs you can test? Seems I can enable it on a 2600x with a 3060 Ti but I don't know if it works properly.
NVIDIA said to use it at your own risk. will it harm or even damage my laptop? i have rtx 3050, i5 10300H, 16gb ram - 2933 mhz
Nah
@@cadecadecadecadecadecade bro that was 5 months ago now nvidia added that feature
Does still work? or has Nvidia managed to optimized this ?
i tested in 2024 legion 5 pro 3070 150W ryzen 5800H 32GB ram ( fast one ) and it increased my fps in lords of the fallen from 92 to 105
It is good for some games for example battlefield 5 but it has its downsides. In my particular case for some reason it doesn't like when I do some idle mining with rebar on. At some point it just hard bricks my pc which gives one long and three short beeps after which I have to reset CMOS. The other thing is that, when I watch RUclips no matter if I use Edge or Firefox my computer just randomly restarts. It never happens while gaming tho so it's not too bad. Ryzen 5800x, 3080ti, x570 tuf gaming plus.
So I have an RX 6600 with the i5 12400, if I enable ReBar, will it work with both an AMD GPU and Intel CPU??
So the card that you have is the eagle 12g version? I just got the same one but I find no reviews anywhere for this 12g skue. Reason I'm asking is because my temps get to 71 to 75 at 1440p. Not too bad but fans are loud. Yours is running at 65. Thanks you
The case itself can make a difference on GPU temps. When I switched my 6800xt into this case from my old one temps dropped a lot.
@@danielowentech I'm just lucky I was able to get a 3080 12g at microcenter last Thursday. I got there at 10 and was only two of them available at 1250 and I told my self that if someone gets it then I'm not buying in or the 1600 dollar one as they are expensive. Luckily I saw one guy get the one and i guarded their display case until they attended me and got it. God I felt so happy. It's the first high end card Ive ever gotten
@@danielowentech what is your clock speed on the card? I'm new to overclocking and since this card has a power limit it's so much I cant do. Thanks
Does 3080ti need to do it? I wonder cuz it came out after 3060 I should be good?
I’m really scared to do a bios update. Lol
How is it now? I just got a 3090. I had to update the vbios to enable resizable bar
well I could activate above 4G decoding and resizable Bar in the UEFI (Gigabyte X570 Aorus Elite) but still can't use rBar because I have a RTX 2080 Super and NGreedia doesn't care abour rBar much, nor on backwards compatibility.
Can you please increase your mouse pointer size? Its hard to follow since its so small even when watching it on a 55 inch TV
Does resizable bar help in Elden ring?
This is Nvidia. They will gatekeep for the next line of GPU and call it "ReBar 2.0"
I have the same mobo (X570 Aorus Elite).
So far got it working only on F32 bios. F36 and F37a (beta) not working, even if the option is available in bios to turn on.
Did not try any bios in between.
How do you get this to even work; even after hitting the magnifying glass on profile inspector there is no ReBar option. 3080 supports it. It's enabled in Bios. MSI control center says its enabled... :(
It's called rbar in inspector
Hey i need help for my building pc, i still confuses between amd and nvidia in term of for streaming and recording, mainly i use davinci resolve for editing, i got budget limit about 1000-1200$ i confused between rx 6600 or rtx 3060, the rtx price is around 630$ in my country and amd about 514$.Thank you in advance
Price wise the 6600 will be a nice GPU. Or step up to the 6600XT ver for the same price of the 3060.
@@linchester8464 thank you, for the advice :D
When it comes to recording/streaming, Nvidia has better compression, so when streaming it needs slower internet speed and when recording, the video files will be smaller. By how much, I don't know. There might be some youtube video analyzing that. Quality of the video should be roughly the same though. Even though I'm generally on AMD side, If you can fit it in your budget I think RTX 3060 is a good choice, but if you want to save money, RX 6600 is perfectly good option too.
@@janbenes3165 thank you mate :D
Recording & streaming? video editing? if you do any of these AMD gpus are not an option since they are really bad at it, just get a Nvidia gpu.

how about with fortnite? is resizable bar good or even usable?
For that "Auto" in Bios...I have Gigabyte motherboard and only option is auto BUT then you must disable Pcie so that is the 3th step.
Huge thanks for this video 👍 I have been on the fence whether to use rebar or not .
It appears to help with fps boost so I'm in 😁 but come on Nvidia 😒 this needs to be supported for more (ALL) games !
I look forward to your future videos ! Liked and subbed 👍
I see the lower GPU usage and higher frames is really nice.
For me resizable bar not work well i get lags in web videos some 1sec blackscreen issues i back already to disable after few hour of testin
What it Do? The Resize Bar?
I don't know what is wrong with metro exodus enhanced editon but i lose a lot fps even tho the game is on nvidia's whitelist. On average i lose 20fps. I have all the required pc parts and it shouldn't worsen my perfomance but rather improve it
Apparently enabling this increases temperatures for cpu and gpu slightly, has anyone experienced this or know if it's unintended with a bug/fixed now?
100x Thanks :) already few frames more in Kena Bridge of Spirits, DOOM Eternal, Bright Memory Infinite . No difference in Crysis Remastered, God of War, Far Cry New Dawn.
I have a RTX 3060 and have it pre installed on it (REBAR), I enabled it and downloaded nvidia profile inspector. Well I don't have the profiles mentioned. It only shows BE and BF, no BA, BB. Is there something else I would need to do or am I SOL?
Did you find it? It's no longer under Unknown settings. Nvidia now has it under "Common" settings. They are now labeled as rBAR Feature, rBAR Options and rBAR Size Limit.

@@100500daniel oh okay, thanks for the info. 👍
Running a game with reBAR off should not cause the issue in RDR2 (and it didn't in any other game, nor on my 6800xt in the same PC). Seems more like a driver issue or something, although it's not obvious why reBAR on would solve it.

I has RX6600 pair with an I5 10400 and my SAM option show as Resizable BAR in Radeon Software, so do i need to change my CPU to AMD to use SAM ?
No in ReBAR mode you still get *some* performance boost. It's just that when you pair a Ryzen with a Radeon you get a tiny bit more.
Just enabled it in the tool's Global Driver Profile and not sorry yet :)
updated my bios to get it, i still don't have the option because i have 9900k rip...

Have you tried it? I would like to know if it is safe to do
@@addictedtoRS Yes, but I didn't notice any difference but I think when doing compute on GPU and there is DMA between CPU/GPU/RAM the resizable BAR can lead to problems or huge performance penalty. Like BAR is 16GB and GPU compute wants access something at 24GB in DDR ram. Then the iommu must rise an exception, move the MMU window then the GPU can access. This brings a lot of latency. Reducing/resize BAR OTOH can lead that the GPU address space fits better into CPU address space, so less iommu tlb translation = less latency. If the bar is super small it might fit into a single iommu region, then it's as fast as without iommu at all.
Anybody know if this helps f1 22 performance or decreases it?
I only wish NVIDIA allows ReBAR for RTX 2000 series. Even with a vBIOS mod. But no, they had to lock everything down and encrypt the vBIOS ! Because they are NVIDIA !
Hey
Do u know when will amd radeon super resolution “rsr” ?
Nvidia's way has a pro. The half of the game that loses fps will not be using it. But they could just give a toggle to enable for all. Nvidia way's biggest downside is that they cannot go verify dozens fo games every month so games get left out.
Personally i don't care as i have a Z390 board so i can't use it reliably anyway.

Will it work with a 2060s? Or just the newer cards
20 series not supported. Only the 30 series.
Surely you know that AMD had had to pull all kinds of tricks due to their GPUs having a smaller bus width, slower vram speed and so it's working with less bandwidth plus data packet speeds are transferring slower. Of course you know. Infinity Cache, you know, why it's there.
It stands the reason, without even straining, that carrying larger data packets at once can be beneficial when you're limited on speed and bandwidth.
If it's not clear then let me try to visualize this. Imagine the bus with as a highway with only 4 lanes, imagine semi trucks carrying the 256 MB packets and they're limited at 55mph. Imagine that data needed doesn't break always fit perfectly in the 256chunks so there will be trucks having to carry the rest of a shipment that would not fit on a single truck.
If the truck carrying the rest of a shipment was able to utilize the other half of it's empty space, you we'll have to sort and separate on the other end.
The Nvidia highway is wider and the trucks can go faster, by design it can afford to send a partial load. Once the data gets through the highway (bus) to the memory, is able to move around faster because Gddr6x
