92% of PC Gamers Forget to Enable This
On all modern GPUs there's a setting which can increase performance substantially, but surprisingly it's usually off by default.
In order to turn it on just head to your BIOS
Go to the “Advanced” tab.
Search for “PCI Configuration”.
Enable “Above 4G Decoding” & “Resize-BAR Support”.
And now your PC should be giving you higher FPS in games that support it. So if you built or bought a new PC don’t forget…

Yes, but not all games benefit from this. Some games it will decrease your fps.
@benjy117 What is that exactly?
And how does it increase/decrease FPS in games?
I swear this guy just makes vids to be relevant,
turning this on while playing games that don’t support can significantly run slower
When I do this and disable cmos it stucks on the mobile screen then when I close and open it again it boots but it's annoying
How to do it on msi?
Where did you get the 92% statistic? "Trust me bro"?

if ypu have gpu z just check advanced tab and select pcie resizeable bar and you can check if these settings are on
Or you can just go in your bios which is pretty much just as simple and wont get reset unless you get bsod lol

Fun Fact:
You can enable this on older generation of GPU's too without any issues.
(it will not give any performance increase, but you can still enable it).
Not Fun but Fact:
and yes its in enable in NAME ONLY
while still DISABLED by DEFAULT since the GPU has no support
Above 4G decoding does actually increase performance, even for many older cards that don't have resizable bar. Resizable bar though only works on some of the 30 series cards and above.
@@ObakuZenCenter Yeah 4G decoding has been round for like a decade+ not ever seen a performance increase... nor decrease. As for resizable bar this depends on graphics card, motherboard and CPU support.
The RTX2080 I had before technically supports it because it's part of the PCI peg spec and so did the Ryzen 3900X and motherboard. Nvidia said nah, it might be because a BIOS update is needed on the graphics card and that's not really for n00bs.

It's not enabled by default because on NVIDIA GPUs it can cause problems and even make some games run slower. For me it only causes stability problems and nothing else. RTX 3060 is my GPU, so be careful with enabling that thing.
above 4G decoding is recomended if you had more than 1 GPU installed on your motherboard.
is for mining

I have the same card and by instinct I avoided enabling it.
This made me go through so many loops. Went to enable this in my bios. Found it kept removing my boot drives. Then I enabled csm with bar enabled and borked everything. I thought maybe my bios was bad so I ended up flashing it to the latest version. That didn't help, But then found that for resizable bar you need to use GPT format for booting with it enabled. So I guess I gotta update my OS now so I can enable that. I'll do it eventually when I reinstall windows someday.
However, the bios update did improve my 5950x performance by around 10% my bios revision must have had issues with the cpu
I had similar issue but it was my boot drive so I switch the boot drive froma 2.5 in sata drive to a nvme ssd
Using CSM is not a good idea. There are security risks, as well as less performance. Just convert the drive to GPT and use EUFI.
lol went through the same issue with the drive not being in GPT. There's a way to convert it but my system files were in another drive for some reason and it was all a big mess but finally got it working.
It’s a pain, there’s a few more settings to change in the UEFI like APIC mode 2x and that works only for newly installed system, so you have to enable that before installing Windows as far as I‘ve read about it.
Learned. But I enable it and tried for some time. Suttering came and I prefere use other settings now
This is great for Amd GPU, you can get a lot of performance with this, but with Nvidia it’s worst in some cases and when it’s supported the difference is irrelevant.
is this setting available on Gigabyte H610M H V3 DDR4 ?
This actually was such a great change, it did my laundry
above 4G decoding is recomended if you had more than 1 GPU installed on your motherboard.
And also if you just have one as it enables access to all of the VRAM.
with out 4g and resizable bar i have 290fps when i enble 4g and Resizable bar my fps go down to 65
Then there's something else wrong with your system that should be fixed. Or you have a really old card with 4 Gb or less of VRAM.
disable 4g have the similar issue
I accidentally enabled it thinking it was for WiFi lol
in my case sometimes make no display or gpu not detected with gpu RX 6600 8GB
Try to disable CSM while using resizeable bar Support. In my Case these both didnt work well together. After disabling this my Problem was solved :) But please tell me If it worked. Interests me a lot
Cant find resizabel bar on my AMD bios.. any tips?
On by default on the last 5x AM5 builds I have done. I only had to enable EXPO and disable on board audio. SAM is enabled by default now on the 4 Gigabyte boards and 1 Asus board I have worked on.
How can enable for board msi ??
As someone who has tested the Resizable bar with Nvidia gpu I can 1000% assure you aren't missing out on any performance. In fact you lose performance by turning it on.
Does IGPU get benefits from resize BAR if enabled without a discrete GPU?
I don't think so its for dedicated gpu
I didn't know about it for years, but after enabling it, I get strange stutters, more like rubberbanding locally.
Make sure your m.2 ssd is up to it, with older pcie gen 3 I've seen it happen more often. I upgraded to a decent gen 4 one and it solved it
You didn't cite sources, you didn't explain why... Basically stranger danger - DO NOT CHANGE BIOS SETTINGS WITHOUT UNDERSTANDING THEM!
I did last night and my pc doesn't boot up anymore so i had to disable again.thanks 👍
When I’m there I don’t see a PCI configuration
Why are all of these videos for the asus Bios... i want to enable this to, but no turtorial seem to help :/
ASRock is not Asus, lol
I understand Re-Bar... but could someone explain the other setting? "Above 4G"
this means you'll use 5g towers in your pc bro
@@tvdootman27 Seems it'll be future proof..."above 4G" could mean 5G and beyond too
/s
It means your card isn't limited to 4 Gb of VRAM, if it happens to have more on it.
@@ObakuZenCenter ?? no
It depends. My current combo (R5 5600, RX 6800) performs consistently worse with resizable bar/SAM on. It's all full of stutters and relatively low GPU usage (70% on vs 98-99% off)
Its for nvidia 3000 or newer, in radeon from rx5000 series
Hmm, curious if my X-99 Deluxe even has the Bar option...thinking not. Find out tomorrow after work.
Yeah bud you don't actually know what you're talking about, in order to do that you have to make sure you have a gpt partition instead of mbr and a few other things, it's not just flip a switch and it's on.
Why would you not already have a gpt partition, thats like, the most basic thing ever. He does know what hes talking about, I'm pretty sure you just didn't set it up properly
Hey i have rtx 3050ti 95 watt gpu in my laptop bit whenver i use my latop tgp use 30 watt this cause so much fps droup pls help if you lnow
laptop has to use more power for games, if you plug it up while u game u won’t have any fps drops due to power consumption
Are these viable for the nvidia GeForce 3060ti??
yes, but just enable 4g, resize bar is garbage
This fixed my pc, i had the worst stutters and fps drops, now its flawless
Amd or Nvidia
Nvdia gpu?
Instruction unclear: i don't have rebar
Flash your BIOS ;)
If you started your BIOS set-up with "load optimized defaults" it should automatically enable this & some other features.
This thing came activated by default to me (rx 6600, asus h610m-ad4, i5 13400)
What is biles
Can you do this without graphics card? I have ryzen 5 5600g
No. Re-bar only is supported on graphics cards, not apu
For all the experts here who have opinions about what A4GD does:
It allows the BIOS and OS to use memory address space above the 32-bit limit (4G) for hardware. This means that the system can allocate resources above the normal limit so the hardware can have a better chance of having its own unshared space and more space if needed. Thus reducing the amount of operations needed for a given function and increasing performance. This is important for things like resizable BAR because that feature allows the CPU to access the GPU’s entire frame buffer in a single operation (instead of just 256MB chunks). Giving hardware access to memory addresses above 4GB is necessary for Resizable BAR to work.
I lot of ppl will brick their potato’s if they do that’s why 😂 you gotta have a good mobo for this.
It's not on a gpu. It's on the motherboard and if it works depends on your cpu and gpu. How do u fail to tell this.
When I do this my enternet don't
Work
thanks! does it chsnce realy something?😅
4g is being disabled when u turn on resize bar
No need to enable, if u update ur bios it automatically enables it
Don’t forget first you NEED to make sure your os will work with csm disabled
How to know it?
A non-clickbait content, nice job.
Do RTX 3070 has this feature?
yes
Also activate XMP or DOCP
nah
Yes 💀💀💀@@oskarieeva2326
for alot of builds this will cause issues with black screens or instability issues, its come and go depending on the user, as long as you update your bios your pc should be set to its best performance while maintaining stability. For example im still booting legacy though i have a 3060 and a i9-12900k, if i do whats said in this video my pc runs like crap, xmp caused blackscreens for me
@@PurrfessorFeline So you buy that super expensive Ram just to run it at slow speeds? Nah.
Did you know there's a glass that when you send electricity through it It becomes foggy
It will be enabled by default (except if you boot from CPU) you might have it disabled.
Because 92% of gamers don't have 4g decode
This actually gave me +60fps in cs2
Meanwhile, my 10 year old pcie 3 gen motherboard
if u do this and ur stuck its eazy to fix it : turn off ur pc and open the case and remove the mobo battery for 10 second and put it back( remove ram stick optional) but i remove it
or just disable csm

Thank you. This will be useful. And I looked it up as always and it does work.
Funny how this "wow it helped" comment it's the only liked one by OP... The rest are complaining due to problems it caused.
it is very needed for intel gpu .
Pro tip : don't listen to this guy and do not open or change anything on the bios unless necessary, more often than not this will make your PC unstable.
Pro tip: dont listen to this guy either.
‘Don’t open BIOS or change any settings unless absolutely necessary’ is such poor advice.
Acting like BIOS is some kind of boogeyman doesn’t help anybody. The vast majority of modern day consumer-grade motherboards have some kind of ‘easy-mode’ which do a pretty great job of isolating the more advanced or dangerous options away from entry level users.
It goes without saying, if you don’t know what it does, don’t mess with it. While you shouldn’t be afraid of the BIOS, you do need to respect it. It’s a powerful tool that, when used properly, can definitely net you great gains; but start messing with things you’re not familiar with and you could very easily break something.
@@LCRich2001
Because in the bios so many things can go wrong depending on alot of factors and what works for someone's PC will brick yours and you could be one setting away from making your pc unstable or bricked so it's not worth it for the average user to risk it.
We have all seen hundreds of people go into endless cycles of instability and blue screen of deaths after a simple visit to the bios. So the average user shouldn't use it unless they have something they need to do there ( like enabling XMP to get actual ram speeds ) and have done their research if it will ruin their PC or not. otherwise changing any setting you don't fully understand what it does is very dangerous and will give you headaches from instability. Point is you can't and shouldn't experiment with anything in the bios, you only mess with what you fully understand. The average user won't know what does what in the bios, thus shouldn't use it if so...
Just reset ur BIOS its not that bad@@rdg665
@@rdg665 this is the exact point I was making. Your original blanket advice of “don’t touch BIOS unless it’s necessary” would mean nobody should go into BIOS to enable XMP, because it’s not necessary.
Better advice would be more like what you’re saying now: ‘not everyone has the same hardware’ ‘it’s very easy for things to go wrong in BIOS’ ‘don’t touch something without full knowledge of what it does’
Your first comment is just devoid of any sort of nuance. You put it plainly: don’t go into BIOS. That’s it… terrible advice.
compare your results with different settings🤯
wrong resize bar often ruin cpu fps and make its 1 % low worse by upto 160 lower fps! this is the case on a 13700k paired with 7900 xtx. by turning off resize bar in cod mw3 my cpu go from 126 to 302 in 1 % low
enabling resizable BAR can result in higher top FPS but lower lows, which can make stuttering more noticeable
@@taylorhappe8026 thats true yes max fps is 30-40 more but lows drops by 160 so not really worth it in my build :)
This is only great for intel Arc GPUs, not so much for nvidia and AMD
i turned it on with my 4060 and i experienced crashing problems lol
There's a reason why it's off! If you want to improve your graphics card and it's Nvidia:
Update Graphics driver & Bios
Watch a video for best performance settings for Geforce control panel settings
Change power settings to high performance
just enable 4g , no need for resize bar

Absolutely wrong.
Unhealthy video. It's off for a reason. It can start crashes, stability issues, make games run slower etc... This option is not for games or performance, its to help with resource allocation issues when using more than 1 devices on the PCIs.
Only if there is something already wrong with your system.
@@ObakuZenCenter No, this option is for users with multiple gpus or anything else using the PCIs. It does not relate to fps gaming boosts.
It’s used for gpu with vram more than 4gb because old algorhitm uses portions of data in 256mb/s between cpu and gpu, if you enable it, your cpu will gain access to your vram “through that bar” which will gain more fps because of the time data transfer between cpu and gpu are lowered. Stability issues seen only on nvidia because intel after multiple driver updates made their gpu stable with rebar on.
Dont forget to disable csm
This video is a scam. Unless you have two GPU's or really going to play on 4k sure put in on. But If you're playing on 1080p or 1440p then FK NO! Let it be on disable. But ofc youtubers never talk about that only the basics, Leaving you with a bigger question mark.
These type of video is the worst since it doesn't explain what it does, never believe anything what it says.

you just need to enable 4g , resize bar should be disable its useless and if you have cpc just disable it if you have amd cpu
🤦♂️ this doesnt help in alot of games. And instead of all modern should say current gen and more specific than that nvidia. 10 and 20 series are still modern. Also amd doesnt use resizable bar it uses sam and is cpu/gpu dependent if you can use it i believe mobo as well.
This setting being on also helps with mining crypto currency as well. Keep it on!
FYI, Enabling re-sizable BAR on my MSI board and RX 5700 XT forced me to short the jumper to reset the BIOS to default settings. As in, it wouldn't detect my video card. So don't just set this willy nilly.
That's because there is something else wrong with your system.
