Ah, so with 16 Prime95 threads the 8 E-cores takes 8 of them, leaving 8 remaining P95 threads to run on the 16 threads of the 8 P-cores. And with some OS threads and other things always going on in the background those 8 P95 threads will bounce around between different OS "cores" (threads) which is exactly what we see in the screenshots.
It's refreshing to hear what I've thought all along, that overclocking for gaming does not have to be Prime95 or Cinebench or Blender stable. You hear gamers say their rigs are Prime95 24/7 stable, it's a waste of performance if all you do is game. If the games you run don't crash, that's all that matters.
@@ivorthomas9437 I'd agree with that to a certain extent, but if it won't pass cinebench or P95 then you know that the system isn't totally stable and perhaps you shouldn't be hammering it 24/7 with those setting?
@@ivorthomas9437 Agreed, It can also acts vice versa, it may appears stable in synthetic workload but as soon as you fire up some heavy cpu games, it may gives a bunch of correctable errors or even BOSD.

You are the first youtuber who approached this topic professionally Very well explained overclock. Step by step After your video overclock is not so terrible You did a good job for which I am grateful.
I want more people to review and test the 12700k as much as this. So far it looks like the most interesting cpu price/performance. But want more indepth.
Right everyone is getting either the 12900k or 12600k. They just flock to what RUclips tells them. The 12700k is probably the best bang for the buck. It’s almost as good as the 5900x/5950x yet it’s $300 cheaper. Meanwhile the 12900k is $600-$1000 which is the dumbest thing ever since you can get 5950x for $700ish. If you can get the 12900k for msrp then it’s a good deal.
This is true but by the time you have run all your stability tests on software you're never going to use, I will have played my games for a few days and known for sure if it will run or not
Yeah, 12700K is the obvious choice. Same P-Cores that seem to OC just as well as the 12900K anecdotally & a lot of Z690 boards come with the preset turbo bins so you can get basically 12900k performance in one click after updating the bios.
Thank you for addressing gaming/mixed workload in terms of power and stability! So often people only look at the extreme of heavy torture tests that load AVX and max power draw.

@@jlelelr No, i7 is a lower binned chip, plus there's less L3 cache, I believe. The cache shouldn't influence OC, but the binning, yes. Probably 200 clocks lower?
Great video as always , agreed that most reviewers focus on the negatives of the 12900k and down talk its potential without considering certain scenarios such as gaming. Keep up the great work!
This is the first time I've seen anyone talk about power limits in the BIOS (thanks for that). I do this on all my machines after testing the limits of my coolers so that the CPU doesn't spend much time above 95C. My current daily machine is a 10850k all core 5Ghz with a 280mm z63 AIO in silent mode. I find that 275 short and 225 long works very well keeping the temps at around 91C while still maintaining 5Ghz for most workloads.
I stuffed my 12900k in a Cooler Master NR200P MAX case. That comes pre-installed with a 240mm AIO for the CPU. My test of Cinebench R23 saw the CPU temps hitting 99-100°C!
the only cooler to keep the 12900k under 100c is like a 420mm cooler, 360mm keeps it around 85-90, but still hit 100 on a few cores... overall what I'm saying is no matter what, unless you under volt the chip it will reach 90-100c in Cinebench R23 ... I also have a 240mm with the 12900k and same issue reaches 80-100c on 4 of the cores in the stress test. I had my i7 970 for 11 years got it in 2010 and only until 2021 did I decide to overclock it .. basically, what I'm saying for gaming and work, you don't need to overclock.... especially with these new intel chips they come overclocked right out of the box from intel, which is why there is less overhead this time in overclocking .. makes no sense in most situations to overclock a lot with these chips.

In the end, you can indeed remove the RGB lighting entirely from the modules.
I would love to see a pure gaming overclock, Ive seen some videos where people put 1 or 2 P core to 5.6ghz and have the rest closer to 5ghz, or maybe even an undervolting guide to get the best temps with highest clocks

Great vid:-) Would you recommend overclocking with XTU? Overclocked my CPU to P-Cores to 5.2 All core, 5.3Ghz on 3cores and 5.4 Ghz on 2cores as well as 4.0Ghz on E-cores. Rock stable with a voltage offset of -0.070v. Hitting 85c with the XTU mem test peaking at 273W at 1.317v. Using a Artic Freezer 420mm AIO cooler.
@@Poppaai In Intel XTU it does not set frequency on specific cores, so I guess the software intelligently select the best cores for the selected frequency on active cores. I tried overclocking from BIOS but it just leaves me with really high idle/load voltage and temps which is something I don't really want. When software is as good as XTU I don't mind it stealing some memory to run in the background, and since I don't use Linux so I don't need to BIOS overclock like I usually do, maybe it will get better with later bios revision though :-) The settings are as follows on perf cores: Up to 2x active cores: 5.4Ghz Up to 5x active cores: 5.3Ghz Up to 8x active cores: 5.2Ggz E-cores are all at 4.0Ghz
I know SLI is long dead since 3090 (and whatever is opinioned to be before that can be true), but I'm curious what the 3090 in SLI would do coupled with DDR5 Memory and the 12900K.
The E cores are heavy on the ring. If you disable them you can get far higher ring clocks which is good for min fps in games. It's no surprise your ring is at just 39x with 40x E-cores. You should be experimenting with lower E-core clocks to maximize ring clock if you're gaming.
@@manlikeg2794 Why bother with 5.2? It's going to require a lot more voltage for no noticeable gain in gaming. 5ghz all core 4.6ghz ring (I have found that core and ring likes running at even numbers for best frametime consistency so 52, 50x core with 48 or 46x ring etc etc) and whatever E-core clock that allows the ring to run at 4.6. You can try for 4.8 on the ring but that might require more voltage than the cores need for 50x. Also, I completely disagree with him on using unstable clocks for gaming. You can crash at any time. If it's not Prime stable it's worthless has always been my motto (one run of 8-256k with 15min FFT size (hammers the caches) and one run of 256-1344k 15 min FFT size(hammers the ring and memory), run it the custom mode, check run FFTs in place and disable AVX!) however since Prime isn't running properly as of now your best bet is probably that memory stress test in XTU he showed until Prime and/or the W11 scheduler is updated. For memory stability testing I use testmem5 with the anta extreme profile. Has been very reliable with DDR4, will probably be with DDR5 as well. Personally I'd disable E-cores, stabilize 50x core and 46x ring, see what voltage 48x ring needs, after that enable E-cores and see how they effect stability. I'd start from 2ghz clocks on them. If you're just gaming you might be better off just disabling them because games like fast core to core communication and fast memory access. The ring connects everything from the L2/L3 cache and the mem controller. Basically you'll need to experiment. Memory overclocking will add a whole other level of complexity to this. You could need more core voltage to stabilize with better fed cores so again if you overclock the memory disable the E-cores till you stabilized the memory OC (for mem OC I first check if its stable in testmem5 than run 256-1344k in Prime to see if the cpu as a whole is stable). All in all tuning ADL with E-cores seems like a pain in the a$$ now that I'm thinking about it. Good luck! 😂
@@TheBlackIdentety thanks for all this info. The e cores do complicate things somewhat. Will have a play around and see what happens. Tempted to pay for a consult for someone on this one 😂
I really love the approach to this subject. But I have two questions: 1. if you increase clocks for the cpu for the intention of gaming, should you set a power limit just in case? what If I want to render a quick video to send to a friend and It uses %100 cpu, the pc could then thermal throttle or crash from instability? 2. if the 12900k boosts to 5.2ghz by itself, should I really be overclocking all core to 5.0ghz? if the game maxes 1 or 2 cores at %100 would I be better off using turbo boost instead of manual all-core OC?
Another great 12th Gen video, thank you, everyone else just keeps doing the same boring standard suite of gaming benchmarks - not very exciting or useful after seeing one or two. I am a bit more interested to see your take on Ryzen 5000 PBO tuning vs manual overclocking. Got my system dialed in pretty well with PBO and have seen tons of random guides here and there on it, but would love to see how you go about it (specifically Curve Optimizer).
Thanks for this info! My 12700K is already pretty decent (177W at max clocks with no power limit specified) so I'm wondering where I can push it further.
I don't know whether it's something you intend to cover or even exists on Alder Lake, but Rocket Lake had some interesting overclocking features (at least in MSI BIOS) that let you adjust the VID curves and set different AVX voltage offsets. Basically lets you undervolt the CPU while retaining normal variable frequency operation and lets you adjust performance using power limits. Sort of like a PBO but with good voltage curve control. Since I use my PC for video rendering quite a lot I found that to be quite useful, since doing an export completely maxes out my cooling.
I disagree with just using gaming as your stability test. Then you forget that your overclock can't handle a heavy workload and you load it, and it ends up crashing half way through a 2 hour job and you lose progress :( ... Which sucks.
Amazing review and guide, was able to get my: i5-12600K Asus Prime Z690m Plus D4 Corsair H100i V2 AIO To a stable all clock P 5.2 GHz E 4.1 GHz 30c Idle, 58c gaming, 85c Cinebench 23 for 10 minutes, following your guide. I was actually able to get a 5.4 all Pcore 4.2 all Ecore OC using the AIOC but haven't been able to replicate it for some reason, decided to work once then poof.
Nice Video. I'm running Noctua D15S air cooler on the Z690 Master and seem to be really stable at 1.35V, 5.1Ghz, 5200mhz DDR5, 68-71c in Temps while playing Warzone.
In you chapters, you said "Stabality". The correct spelling is Stability. And yes, something can be ustable but have instablility issues. Small tip. Keep up the great work!
I bought this motherboard. No matter what I change in bios my temps won't come down. Voltage also shoots up between 1.4 to 1.53. My package watts is always over 300w, VID Max is always at 1.3 to1.45+. I have a custom water loop with 2 360m rads.
Nice video Roman. I just wonder why Remnant only used between 2 - 12% of the CPU? This also explains the low peak temperature while in the game. I would imagine that a game which would use 25% or more of the CPU would make it run way hotter, say for example Battlefield. Or am I wrong maybe?
Everyone seems to have better luck than I have when it comes to DDR5 XMP profiles. If I set mine, it'll boot into Windows, but once there, it's unusable. If it doesn't instantly bluescreen, every application will immediately crash after being ran. And this is a mild 5200 kit from Corsair.
You really should caution people right now when recommending XTU with Alder Lake because the max P-Core ratio you can create in a new profile is 4Ghz which is way worse than the stock settings and it can be a confusing thing to fix with XTU writing directly to the chipset’s firmware. Running games with E-Cores disabled hoping that I will be able to re-enable them in the future as I’m unsure of how to do the scroll-lock workaround that Intel recommends. Could be a good video topic. I have two OC profiles one that’s 6Ghz without C-states & and AVX offset and a more reasonable one where I modified the boost-bin voltages to attain a 5.5-5.7Ghz boost frequency which is averaging out to 5.4 in benchmarks with relative ease & only 2V on the core. Very happy with the overclocking headroom on my 12700K.
I notice you hit the thermal throttling limits at some point during your testing. Might XTU during the CPU test have hit thermal limits, and that's why it didn't pull as much power? I suspect that's the case.
What could I do if I wanna slightly over clock but I am running into a cooling issue, is there a way I can reduce the voltage a bit to minimize the higher temps? I have the same setup as you and my cores are hitting 100 degrees consistently?
Awesome video, thank you! Would you say that 3DMark TimeSpy is a good analog for gaming, and usable in order to systematically design one's "gaming OC?"
Danke Schon! Can u touch a bit more memory overclocking in the next video please. Thanks again. Cant wait to play with the chip as well just waiting for my Mobo to come in, hopefully by Christmas when im off work it will arrive and i can build my system.
Noob here. I have to disable e-cores since I can't update to Win 11 and Win 10 doesn't handle them very well. The problem is that by doing so, the ring frequency will shoot up to 3.6 ghz to 4.7 ghz, and temps will follow. So, what should I do next in this situation? Manually reverting back the ring frequency to 3.6 ghz or anything else? And what are the implications of such next move? being it what I tried to guess or literally anything else that you'll suggest me. Thanks in advance
At 17:20 you are using a 1050TI. Doesn’t this mean that the gpu is bottlenecking and thus it’s not a fair representation of the load the pc would be under if your cpu is the bottleneck? (Play cs at 1080p maybe?)
yep clock speeds i have an i9 12900ks that i have now had for 3 months max clock speeds in games seams to be 4ghz no were near 5.5ghz would be nice to get it to run faster than my old i9 9900k that runs at 5ghz, this also means my i9 9900k is now back as my main gaming system as it runs game much smother and faster than the i9 12900ks
Thanks for the video! I have one question. Let's say you're doing more rendering/encoding/ etc. How should you setup the OC setup? The auto setting crashes my PC and I'm using a 420 arctic liquid cooler...
Hold on a minute here. There is a big question this video calls for. Der8auer repeatedly refers to his cat as a she. When we all know ginger cats are all male. A female ginger cat, that would be like winning the silicon lottery
At 5.3G with 1.36v on a 420mm cooler. Temps in 2042 never go higher than 60c and usually hover around 45-50. I may have got lucky. E cores disabled as at the moment they hit the FPS
Why would you disable the e-cores? Because disabling e-cores provides better performance in the majority of cpu bound games. Also, e-cores can introduce micro stuttering issues in some games.
Hey Roman! I Like most of your videos, but i think all core / static voltage overclocking is dead nowadays. Could you make a video doing CPU overclocking by using TVB, per/core ratio configs, etc? For me most interesting question is how to find correct voltage / stability when you use per-core overclocking.
So for gaming is it better to OC the e cores or to turn e cores off and up the ring clock as usual? Would be to to know which will give best gaming performance
Is it also stable with Command Rate 1T for the memory? Cause CPU-Z does not detect the gear down mode and it shows 1T if your CR is set to 1T while the memory controller is set to gear down mode. And what is your p-core clock speed recommendation for absolute stability even with the AVX 512 instructions if you have a 360mm AIO?

If it's not Prime stable it's worthless has always been my motto (one run of 8-256k with 15min FFT size (hammers the caches) and one run of 256-1344k 15 min FFT size(hammers the ring and memory), run it the custom mode, check run FFTs in place and disable AVX!) however since Prime isn't running properly as of now your best bet is probably that memory stress test in XTU he showed until Prime and/or the W11 scheduler is updated.
For memory stability testing I use testmem5 with the anta extreme profile. Has been very reliable with DDR4, will probably be with DDR5 as well.
Personally I'd disable E-cores, stabilize 50x core and 46x ring, see what voltage 48x ring needs, after that enable E-cores and see how they effect stability. I'd start from 2ghz clocks on them. If you're just gaming you might be better off just disabling them because games like fast core to core communication and fast memory access. The ring connects everything from the L2/L3 cache and the mem controller. Basically you'll need to experiment. Memory overclocking will add a whole other level of complexity to this. You could need more core voltage to stabilize with better fed cores so again if you overclock the memory disable the E-cores till you stabilized the memory OC (for mem OC I first check if its stable in testmem5 than run 256-1344k in Prime to see if the cpu as a whole is stable).
All in all tuning ADL with E-cores seems like a pain in the a$$ now that I'm thinking about it. Good luck! 😂
@@TheBlackIdentety thanks for all this info. The e cores do complicate things somewhat. Will have a play around and see what happens. Tempted to pay for a consult for someone on this one 😂
I really love the approach to this subject.
But I have two questions:
1. if you increase clocks for the cpu for the intention of gaming, should you set a power limit just in case? what If I want to render a quick video to send to a friend and It uses %100 cpu, the pc could then thermal throttle or crash from instability?
2. if the 12900k boosts to 5.2ghz by itself, should I really be overclocking all core to 5.0ghz? if the game maxes 1 or 2 cores at %100 would I be better off using turbo boost instead of manual all-core OC?
I appreciate the way you explained everything here ,amazing
Another great 12th Gen video, thank you, everyone else just keeps doing the same boring standard suite of gaming benchmarks - not very exciting or useful after seeing one or two. I am a bit more interested to see your take on Ryzen 5000 PBO tuning vs manual overclocking. Got my system dialed in pretty well with PBO and have seen tons of random guides here and there on it, but would love to see how you go about it (specifically Curve Optimizer).
I rather decrease the frequency a bit than increase the voltage for everyday usage and set power limit for the CPU in case of AVX workload.
Everyone Thank Der8auer for all the great VRM's we got. He did in fact make the 1st VRM Disaster video...
I love your cat 14:32
Nice quality content, thank you
Thanks for this info! My 12700K is already pretty decent (177W at max clocks with no power limit specified) so I'm wondering where I can push it further.
I don't know whether it's something you intend to cover or even exists on Alder Lake, but Rocket Lake had some interesting overclocking features (at least in MSI BIOS) that let you adjust the VID curves and set different AVX voltage offsets. Basically lets you undervolt the CPU while retaining normal variable frequency operation and lets you adjust performance using power limits. Sort of like a PBO but with good voltage curve control. Since I use my PC for video rendering quite a lot I found that to be quite useful, since doing an export completely maxes out my cooling.
I disagree with just using gaming as your stability test. Then you forget that your overclock can't handle a heavy workload and you load it, and it ends up crashing half way through a 2 hour job and you lose progress :( ... Which sucks.
Amazing review and guide, was able to get my:
i5-12600K
Asus Prime Z690m Plus D4
Corsair H100i V2 AIO
To a stable all clock P 5.2 GHz E 4.1 GHz
30c Idle, 58c gaming, 85c Cinebench 23 for 10 minutes, following your guide. I was actually able to get a 5.4 all Pcore 4.2 all Ecore OC using the AIOC but haven't been able to replicate it for some reason, decided to work once then poof.
Nice Video. I'm running Noctua D15S air cooler on the Z690 Master and seem to be really stable at 1.35V, 5.1Ghz, 5200mhz DDR5, 68-71c in Temps while playing Warzone.
In you chapters, you said "Stabality". The correct spelling is Stability. And yes, something can be ustable but have instablility issues. Small tip. Keep up the great work!
Could you please show a detailed video like this on how to undervolt the i9-12900k while still having good performance. Thanks
I would love some more information on the 12700k, also how about a few cores at higher frequencies for gaming?
You are the man, much gratitude
I bought this motherboard. No matter what I change in bios my temps won't come down. Voltage also shoots up between 1.4 to 1.53. My package watts is always over 300w, VID Max is always at 1.3 to1.45+. I have a custom water loop with 2 360m rads.
thank you very much derbauer! really helped me a lot on this video!
Great video. The only thing you missed here was your load line calibration setting.
Thanks Ronan, I should get my water cooled 12900k up and running in the next few days after I secured some DDR5 yesterday.
Great video, thanks man!!
What's the LLC level for 1.3V of this configuration?
To reduce the temperature and therefore the consumption, you should activate the LLC (Load line calibration) in mode 4
The only tempting board for going Z690.
Hi Der8auer the timestamp at 15:54 should be "Stability" instead "Stabality" cheers
Very nice video again, thank you, I really appreciate this! :)
Great video
awesome video, thank you sir!
Disable E cores for gaming run P cores at higher mhz I found the biggest fps gains getting more gpu utilization that way.
Well said at the end. I only game on my system so I use that as stability testing for OC.
Thank you.
debauer giving just the right amount of details. great vid, sure it will help the noobs get some good oc profiles
The best game test for overclock for me is Battlefield V. If the game runs smooth like butter your overclock is perfectly stable.
Wow, there are a lot more OC features and areas of control on these modern CPUs!
Very informative gonna use this as a base to oc 12700k mainly going to be used just for gaming exactly like you said
Nice video Roman. I just wonder why Remnant only used between 2 - 12% of the CPU? This also explains the low peak temperature while in the game. I would imagine that a game which would use 25% or more of the CPU would make it run way hotter, say for example Battlefield. Or am I wrong maybe?
Sheikh is my favorite part of your videos. Such a sweet cat.
I would like to see you expand on the P vs E cores. Maybe a streaming benchmark with P cores for gaming and streaming only from the E cores...
Everyone seems to have better luck than I have when it comes to DDR5 XMP profiles. If I set mine, it'll boot into Windows, but once there, it's unusable. If it doesn't instantly bluescreen, every application will immediately crash after being ran. And this is a mild 5200 kit from Corsair.
You really should caution people right now when recommending XTU with Alder Lake because the max P-Core ratio you can create in a new profile is 4Ghz which is way worse than the stock settings and it can be a confusing thing to fix with XTU writing directly to the chipset’s firmware.
Running games with E-Cores disabled hoping that I will be able to re-enable them in the future as I’m unsure of how to do the scroll-lock workaround that Intel recommends. Could be a good video topic.
I have two OC profiles one that’s 6Ghz without C-states & and AVX offset and a more reasonable one where I modified the boost-bin voltages to attain a 5.5-5.7Ghz boost frequency which is averaging out to 5.4 in benchmarks with relative ease & only 2V on the core. Very happy with the overclocking headroom on my 12700K.
ah, yes. I run all my CPUs at 2V as well
That cat is overclocked on cuteness.
I notice you hit the thermal throttling limits at some point during your testing. Might XTU during the CPU test have hit thermal limits, and that's why it didn't pull as much power? I suspect that's the case.
Would love to see a custom loop overclock on the 12900k please great video again.
What could I do if I wanna slightly over clock but I am running into a cooling issue, is there a way I can reduce the voltage a bit to minimize the higher temps? I have the same setup as you and my cores are hitting 100 degrees consistently?
i saw buildzoid mentioned that by disabling E cores you can drastically increase Ring Ratio
Inbuilt FIVR is a good concept. Intel should have stuck to it for all generations
Cute you have a puppy cat too, mine also can't help but to be in the same room, and heaven forbid you try to close a door lol.
Awesome video, thank you! Would you say that 3DMark TimeSpy is a good analog for gaming, and usable in order to systematically design one's "gaming OC?"
Does lowering the long duration power to 150 as mentioned sacrifice performance from the CPU?
3:30 Right nyaow
Danke Schon! Can u touch a bit more memory overclocking in the next video please. Thanks again. Cant wait to play with the chip as well just waiting for my Mobo to come in, hopefully by Christmas when im off work it will arrive and i can build my system.
Noob here. I have to disable e-cores since I can't update to Win 11 and Win 10 doesn't handle them very well. The problem is that by doing so, the ring frequency will shoot up to 3.6 ghz to 4.7 ghz, and temps will follow. So, what should I do next in this situation? Manually reverting back the ring frequency to 3.6 ghz or anything else? And what are the implications of such next move? being it what I tried to guess or literally anything else that you'll suggest me. Thanks in advance
At 17:20 you are using a 1050TI. Doesn’t this mean that the gpu is bottlenecking and thus it’s not a fair representation of the load the pc would be under if your cpu is the bottleneck? (Play cs at 1080p maybe?)
Yes absolutely. Will always depend on the GPU/Game/Usecase
@@der8auer-en okay, so then why didn’t you use a more relevant GPU more likely to be paired with the i9
No game would likely bottleneck an i9 so the 1050ti is just a troll??
@@Profanitey you might not see a huge difference if the game cant utilize all the cpu to begin with
yep clock speeds i have an i9 12900ks that i have now had for 3 months max clock speeds in games seams to be 4ghz no were near 5.5ghz would be nice to get it to run faster than my old i9 9900k that runs at 5ghz, this also means my i9 9900k is now back as my main gaming system as it runs game much smother and faster than the i9 12900ks
have you made a updated 12900k overclocking guide? Whats the best clocking for getting the most fps in games?
Thanks for the video!
I have one question. Let's say you're doing more rendering/encoding/ etc. How should you setup the OC setup? The auto setting crashes my PC and I'm using a 420 arctic liquid cooler...
Hold on a minute here. There is a big question this video calls for. Der8auer repeatedly refers to his cat as a she. When we all know ginger cats are all male. A female ginger cat, that would be like winning the silicon lottery
ty
TY
Is there still going to be a follow up/advanced overclocking video?
At 5.3G with 1.36v on a 420mm cooler. Temps in 2042 never go higher than 60c and usually hover around 45-50. I may have got lucky. E cores disabled as at the moment they hit the FPS
Try running cinebench r23 and check your cpu temps. Gaming temps for a 12900k shouldn't go over 65-70 while gaming.
Why no one uses per core overclock ? Wouldn't that yield better single thread and low thread for gaming ?
Do you plan on doing any BIOS overclocking overviews for Gigabyte and ASUS?
What LLC Level are you running brother? Thanks
Would your recommend delliding the 12900k? Also how would you ideally mount an aio in a case and the top or front?
Why would you disable the e-cores? Because disabling e-cores provides better performance in the majority of cpu bound games. Also, e-cores can introduce micro stuttering issues in some games.
did you talk to yourself on a regular basis?
@@brunodinis7454Did you learn english from an indian gas station owner?
Had so many problems with those stupid E-Cores on. Disabled it instantly.
there is a new version of Prime95 that allowed you to use all the cores
Why not undervolting?, the result is the same but lower voltages, temperatures and power draw
Hey Roman!
I Like most of your videos, but i think all core / static voltage overclocking is dead nowadays.
Could you make a video doing CPU overclocking by using TVB, per/core ratio configs, etc?
For me most interesting question is how to find correct voltage / stability when you use per-core overclocking.
So for gaming is it better to OC the e cores or to turn e cores off and up the ring clock as usual? Would be to to know which will give best gaming performance
Hmm I never knew that about the 4790k
That's really interesting
Is it also stable with Command Rate 1T for the memory? Cause CPU-Z does not detect the gear down mode and it shows 1T if your CR is set to 1T while the memory controller is set to gear down mode. And what is your p-core clock speed recommendation for absolute stability even with the AVX 512 instructions if you have a 360mm AIO?
I have a -0.100 offset on my 12900k, but I wonder if a flat offset is a negative thing when idle.
Is there any way to change clock automatically by load? For example, when you game, sets clock to 5200, and when you bench, sets clock to 5000.
is the msi z690 unify-x the best motherboard for me? Going to use it for gaming/streaming.
so far, i have the following:
-12900k
-3090 ftw3 hybrid
-7000D airflow corsair case
-latest 420mm aio from corsair
-Seagate FireCuda 530 4TB Solid State Drive - M.2 PCIe Gen4 ×4 NVMe 1.4
-G.Skill Trident Z5 RGB Series 32GB (2 x 16GB) 288-Pin SDRAM DDR5 6000 (PC5-48000) CL36-36-36-76 1.30V Dual Channel Desktop Memory Model F5-6000U3636E16GA2-TZ5RS
-MEG Z690 UNIFY-X (fuck it. just ordered it. lol)
I just need to decide on the motherboard, paste, psu (debating between 1200 and 1600 watt), and streaming stuff (I need to research this because I don't know anything about streaming but I know i want the absolute best of everything)
I think i'm at 5k and I havent even bought a psu yet. lol
What about liquid metal as a TIM? Could it help reduce 6-8 degrees as it was before?
Does Samsung have an equivalent B-Die for DDR5? What fabrication tech is each memory manufacturer using? Google says Samsung's B-Die was made at Samsung using their 20nm.
Can you do a video on per-core OC with VF tuning?
