- 23% Faster - Fix the 7950X3D & 7900X3D
On the left is a stock 7950X3D in Baldurs Gate 3, and if you look closely you can see the first 8 cores aren’t being utilized.
Those are the X3D cores which for Baldur’s Gate and many other games is a major issue that will lead to much lower performance.
Now many will tell you this is unfixable and to buy a 7800X3D instead, but actually it is and the fix is very easy, yet for some reason AMD didn’t do it.
To prove it on the right I have the same scenario, except this time with the fix, and as you can see, now the X3D cores are being utilized, which actually led to a 23% performance gain.
So what’s the fix? Simple.
Go into your BIOS
Press F7 to go to advanced
Find “Precision Boost Overdrive” and on ASUS under “Per-Core Boost Clock Limit” or something with a similar name on other boards (which if you can’t find it most motherboards have a search function at the top of the BIOS) Anyway once you find it, enable it and limit your non X3D cores (which are the ones that are set to clock much higher) to less than your X3D cores, I personally run 5050MHz as the max, then hit F10 to save and quit.
Now before you panic I have tested this and not only is it the only fix that always works, but it also has 0 performance decrease in any multicore or gaming workloads.
It’s an incredibly simple and safe fix because Windows typically tries to grab the highest clocking cores, so even if you have the latest chipset drivers and game bar update this is why some games still will grab the non cache cores which clock much higher.
So why didn’t AMD do this? I’m not sure. Maybe they actually thought it would be better not to, or maybe they just wanted to put 5.7GHz on the box and didn’t care that it was all negatives and no gains.
We’ll never know, but I think it’s VERY important this reaches ALL 7950 and 7900 X3D owners, so if this helped please like the video, favorite, tell me how much performance you gained in the comments, and if you could please share this on places like Reddit or other AMD forums that would be really helpful.

Wow what? A video that's not 10 minutes long, straight to the point and no unnecessary blabbing? Is this the right channel?
Mind blowing.. some videos aren't all numbers and charts. Tiktok might work better for your attention span
You compleatly missed the comments intent..
It also happens to be absolutely TERRIBLE advice that nobody should follow. This will absolutely negatively impact performance in many applications that "Graphically Challenged" simply didn't test for, and people are *STILL* posting this awful advice as a "good idea."
@@hellraserfleshlight Of course he didn't. He was like "more FPS = good" no matter the cost. I don't know about you but a 7950X3D is already powerful enough. It's a 7800X3D if you disable the second CCD.
@@laszlozsurka8991 the point of the vid is you can still use the 7950x3d as a 16 core cpu if required with this fix
That works damn. Tested on Starfield, 99% fps raised from 55 to 70. Thank you bro!
@jeffrey1296 As far as I know only the 3D versions of cpu have a different max clockspeed on core using the 3d cache. Non 3D cores have the same speed so it's not gonna change anything since you don't have to force the game to use specific core to use the cache anyway.
@@Jeycht Yes, this is a problem with the die itself as only 1/2 of the cores use the 3D cache but due to HW limitation they are clocked lower. The problem with that is that the OS scheduler doesnt know that so it defaults to the higher clocked cores and ignores the other ones. So basically you get half a CPU. The fix is the same butchering the CPU by forcing the OS to use the faster cores. Its pretty much the same as Intel P and E cores.
If you mostly game , buy the 7800X3D as that one is preset (it has only 1 die) while the 9 has 1 that sits at idle in gaming.
If you are going for productivity and Virtualization the standard non 3D CPU is much better because all the cores are the same and OS scheduler is able to utilize all of them + 3d cache doesnt work for most programs , its only good for Gaming.
@@mowtow90 unreal engine benefits from vcache
Open the game > hit Windows+G > click on settings and check _this is a game_ and restart. Windows gamebar will always try to use the cache CCD for games.
Does this method give good results without need to lower the non vcash cores frequancy
@@Adel-sj4ue For me with the previous and the latest drivers, always the CCD0 (Cache cores) are selected. And I checked them both from all platforms (XBOX, Steam, Epic). All the games where automatically triggered the cache cores.
Yes this works for me!
how do u do this@@georgek6322
Isnt there another way? I always delete gamebar
I remember watching some of your older videos, didn't like them, thought you were extremely click baity. This video is helpful though and to the point, I think you changed my mind
Either that or you can use Process Lasso to set the game application to prioritize the X3D cores. But this works too.
From your experience which give better results process lasso or this method?
Process Lasso wouldn't have to lower the clock speed of the non 3D cores, so it would be faster.
do you have video link how to use process lasso?
Certain games will crash or not open using process lasso because of the anticheat software thinking it's a bad program. Elden Ring would flat out not open for me until I uninstalled it.
@@boomslangj new info
This still works! Huge bump in frame rate and stable .Soo glad i came across your video! On the MSI board i have, it was a Cache core prioritize setting i found with search
can you not just achieve the same result using process lasso or the gamebar? You don't need to de-clock the frequency cores anymore
This is a bad fix. It may work, but it's not the correct way to do it. Use Process Lasso (free program) to set the affinity for each game to the v-cache CCD. This gives up no multi-threaded performance at all, but accomplishes the same goal of forcing the game to use the correct CCD.
Can you tell me what to do on Project Lasso? or link me something thatll tell me. would appreciate it
Certain games will crash or not open using process lasso because of the anticheat software. So his fix is not all that bad.
@@clarenceoveur9497 some games you might have to change the core affinity in process lasso after you launch the game. so far only elden ring for me. also, process lasso makes it easier to select just the cache or frequency cores, or even all cores with just one click. before they updated it you would have to manually select every core on or off
If i had to guess, this probably lets the X3D CPU use the same scheduling optimizations used by Intel's hybrid cores...P cores higher clocked than E cores
Yes. It is how Win 11 works and AMD botched this cpu, going against Win 11 scheduler.
Intel didn't
Thanks to this video I pulled the trigger on buying a 7950x3D, Thank you!
Ditto
Is this still a suggested method in May 2024, or have driver and game updates fixed this?
UP
Straight to the point! Havnt tested it yet, but it makes sense.
I appreciate the tip,but i still think for a overall benefit. Using the negative 30 undervolt still seems like our best choice.
How the negative 30 undervolt will fix this problem????
@@Adel-sj4ue actually i got even better results using a negative 25 undervolt on all cores. with internal gpu disabled my system is running at 5235mhz and 5725mhz. @48-59degrees. I do run my fans on 100% when gaming or benching, but with my 360mm kraken, and the negative 25 undervolt, im running at 5725mhz under 60 degrees while benching. i love this cpu. i think my motherboard helps, i really love the gigabyte aorus x67E master
Exactly. What's the point for downgrading your non 3d cache cores if you can undervolt the cpu and get 5225 on 3d and 5700ish on the non 3d's.
@mattw6597 I upgraded to February's bios and set my ram first. Then once I got my boot up time to under 40 seconds (it was taking over 64seconds) . I then made a few changes for cpu and now I have my c0 running at 5325mhz and c1 running at 5735mhz. My benchmarks are all up, my multicore benchmarks now are even or within margin of error of the ryzen 9 7950 multicore. In game benchmarks the scores were insane. One dx10 rtx benchmark I use had a high score of over 950fps(the highest I've ever seen before that was around 700fps).
The thing now is even when I run stress tests my high temperatures are in the low 70's. During regular types of benchmarks by 3dmark my cpu temps were in 50's making me want to go in and turn up the settings because I have alot of temperature headroom but you and I know as soon as I mess with it more something will happen. I'm honestly just happy I finally got the ram to stop retraining so long and running at alittle over 6000mhz.
What multicore benchmarks did you do? Limiting your non 3D cores to 5050 seems like a substantial downgrade.
Even though he said it didn't lower the scores at all 😂 🦻
HOW did AMD not figure this out?!??
AMD what? You find it normal to reduce the performance of your processor for anything else to just get the boost in games? If you want only games and bought the 7950X3d you purchased the wrong processor. 7800X3d is the one you truly needed.
@@georgek6322 do you know which one is best for streaming and gaming?
@@spamfamjay7023 For streaming competitive gaming for example at 4K - 60fps you need a capture card to take the task so that you don't get a performance hit in the game with inconsistent fps. Most of the serious streamers do that.
7950x3d if you wanna game stream anf render if you just wanna game 7800x3d,i wouldnt bother thst much over the 7900x3d
Selohcin, this is Windows Scheduler issue not AMD one. On Linux they don't have such problems and is why both 7900X3D and 7950X3D perform better there.
I use process lasso set up properly and it works perfectly with the 7950x3d
a must have tool
If my info is correct you just need to tell games to use ONLY the vcached cores with process lasso?
@@dukejukem8843 Yup. You can just make a rule that anything in /Program Files/Steam runs on X3D-cores for example
True for this game but some games will use more than 8 cores for Max performance, as well EAC blocks this pretty heavily
EAC blocks process lasso ?@@AsthmaQueen
I just got the 7900x3d because it was the same price as the 7800x3d on Black Friday. Now I'm trying to figure out everything.
Finally. I got 19-26% on various games with this method. Setting the max clock needs playing with but overall yea the 7900x3d beats the 7800x3d which is nice.
what motherboard you have@@thenext9537
Good luck with the am5 socket burn @@thenext9537
Did this work for you ?
Just got the 7900x3d and i got stutters in warzone...@@thenext9537
I just got the 7900X3D as well. Did you change anything except the steps that were shown in this video? I wonder if Gamebar has improved since then
Why don't you just set in de BIOS to "always prefer V Cache"?
Каким, блядь, раком ты это установишь на Asus x670e Hero?!
He will take your idea and do another video. It is about subscribers and views. Nothing else matters 😂
My BIOS lets me select whether I want the CPU to favor frequency, cache, auto or "driver". Also turning on Windows Game Mode should enable this as well.
This way that he showed is better no more switching
The price on the 7900X3D has dropped again and it is less than the 7800X3D on Amazon. With a little bit of configuration in the BIOS or Process Lasso, you can get the 7900X3D to run about the same speed as the 7800X3D while gaming and faster than the 7800X3D in productivity tasks. Same 120W TDP.
I just wanted to say I saw a substantial improvement!
I went from 38FPS in 3Dmark Timespy to 56 FPS!
I gained 1033 3Dmark timespy score.
Timespy before tweak 16,996
Timespy after tweak 18029
CPU FPS before tweak 40.99
CPU FPS after tweak 55.33
CPU paired with 64GB G.Skill Z5 memory CL36 & RTX 3080 10gb
So what clocks would be good for 7900x3d?
What about undervolt? In my experience if you gonna udervolt it gives you less temp and higher clocks speed.
I'm planning on building me an all AMD PC. I'm going with Ryzen 7950x3d with an Aquris liquid cool 7900xtx gpu.
Hey bro!
Nice job! Congrats first of all
When you say this method + oc, you mean oc by using PBO? What do you think if I use your method + curve optimizer( undervolting)?
I have 7900x3d but i dont have any option to change Per core or anybting.. x670 aorus mbo
Process Lasso is a better solution anyways.
I mean it makes sense, i would love a 7900x3d over a 7800x3d. But im kinda being put off with all the comments about gaming preformance, would this apply for all games etc ? No issues ?
This does lower the boost clock speed of 4 core, it should lower multi-thread speed on tasks that uses all cores, assuming cooling is good enough to keep the boost clock speed to max. May not see the lost of speed on multi-thread task that use all core if not able to keep boost clock speed running at max speed.
Please i have a question
After the fix when compared to 7800x3d
Does it give equal or better results than the 7800x3d???
Yes. Many videos on this. Its only about 1-2% better though. Margin of error
Thank you so much
Doesn't that just limit the frequency reachable by the non-x3d cores (cores which typically boost way higher than the x3d cores because they are less thermally constrained because they don't have 3d vcache stacked on top)? so doing this "fix" should improve gaming performance by telling windows the faster cores are the x3d ones, but it could also significantly decrease performance in workloads that don't use the vcache...
You’ll be hard pressed to find any real world applications where it makes any difference at all.
@@GraphicallyChallenged Small number bad. Big number Good :))
Idk, Windows is a pretty real world application to me
Personally would not use this method, but rather process lasso or something else that doesn't affect entire system performance
Yeah, it does significantly reduce performance. Don't listen to people it doesn't. Bro, it is literally 500-700 mhz
"Hard pressed"? More like *definitely*
If you do this, won't ALL programs use the V cache chiplet? That's like a 10% difference in performance (downwards) for serious programs that use 8 cores max.

So I have fairly little experience with PBO settings, but is this essentially a type of overclocking or does it just activate the other cores as it should?
This is actually a form of underclocking your non-3D cores, so essentially you lose productivity power, but you make 3D cache cores as priority in Windows 11. Because Win 11 scheduler starts using higher clocked cores first. Same as 13900k has P-Cores at higher clocks, and Windows knows what to use first.
This is far from ideal solution for anything but the gaming.
7950x is a better design, but not as strong for gaming.
7950x has even spread across all cores, but still not strong enough to beat 13900k.
@@righteousone845413900k has a better memory controller.
How does an "unlocked" 7950x3d compare to a 7800x3d?
For gaming specifically, how much performance increase would the 7950X3D have over the 7800X3D assuming the fix is applied?
Great question, I also want to know.
In most cases about 2% as the clocks of the V Cache chiplet of the 7950X3D are a tiny bit higher than the 7800X3D.

Process Lasso should fix the issue as well without requiring downclocking.
Sounds to me like a Microsoft problem and their POS Windows
Its a scheduler related issue but it's not Microsoft's issue. AMD needs to address it in their chipset drivers for the 3D CPUs. Its not Microsoft's job to address customizations of a particular CPU. AMD and Intel give Microsoft direction on how to use the scheduler to take advantage of their CPUs the way they want. I have the 7950x3D and it has gotten better with new chipset drivers. AMD Zjust needs to stay on top of it. No different than when they release new video card drivers for new games.
we'll have to wait and see if Linux wizards manage to drop a plug and play fix that does an even better job. Proton and Wine have really been doing some magic lately to fix all the weird stuff.
@@GSP-76
You're just like my Ex: "If you loved me, you wouldn't have to ask what's wrong with me"
:)))
When you launch an application, the Operating System needs to tell the CPU what type of application that is.
Is it something that is highly multithreaded? Is it a game? Is it a production application?
The OS KNOWS which chip is inside your system. It should KNOW what to say to the chip.
Unfortunately, if the OS doesn't recognise BG3 as a game, because it's a new game, the cores with the vertically stacked cache won't get used.
The CPU does whatever the OS tells it to do. The responsability of managing resources falls on the OS. Not the Chip.
The chipset-drivers are just there to ensure that your Mobo will boot up your CPU and Clock accordingly to spec.
@@GSP-76 But then why do people have to switch to Windows 11 to get better performance on Intel CPUs with 2 types of cores? Is it not chipset related or can Microsoft only fix that issue for Intel?
I think the issue is that AMD simply dropped this problem out of the blue while Intel has announced their mixed cores 12th architecture about 3 or even 4 years before releasing it.
AMD literally said they put the 3D V-cache only on one CCX because there was no increase in performance when going from 8 to 16 cores.

Is this satire? This will absolutely have a negative performance impact on single or lightly threaded, clock speed sensitive workloads (this is a LOT of things, including many games). You are limiting your fastest CCD, which is better for non-cache sensitive applications, to much lower speeds to fix something that you can do with free software and *not* gimp your performance.
Yo anyone in here using a rog stix with the 7950x3d with a negative offset? What llc are you using?
I've looked everywhere I don't know how to do it in aorus bios :(
Has anyone tested this on games like Fortnite and Warzone? I use process lasso to lock the games to my cache CCDs, but I wonder if this would help as well.
This is a needlessly convoluted solution which will only lead to decreased performance in productivity workloads (if you don't have productivity workloads and just use it to game, why do you even have this CPU?? 7800X3D is objectively better if you're only going to game), not to mention it relies on current implementation details of the Windows thread scheduler AND with this method the game WILL still use the non-X3D cores if it asks for more than 16 threads from the OS at the same time.
If a game isn't using the X3D CCD you can always set the CPU Affinity for that process to the correct hardware threads (using a startup script or a program like "process lasso"), or use Windows gamebar as someone else explained in another comment.
Can you elaborate on the game bar thing?
@@itscoolthough419 I just responded to you with a link but the comment is gone, maybe comments with links are getting deleted on youtube? Just search for an official AMD article "How To Set Up Your System with A New AMD Ryzen 9 7950X3D Or Ryzen 9 7900X3D Processor"
Thank you for this
I guess this does nothing to the 5800x3d and the 7800x3d Cos there on single ccx ? or something
This only applies to CPUs that have multiple CCDs, the 5800 and 7800 only use 1 vcache CCD. So, yes.
how to overclock using this motherboard MSI MAG B650 TOMAHAWK WIFI
Dear Graphically Challenged,
Can you please tell me the name of the Software for looking at the CPU cores.
Thank you :)
HW Info
Thank You :)@@GraphicallyChallenged
@@GraphicallyChallenged It is possible to limit the Non X3D cores with the "Ryzen Master" software?
or can this only be done with BIOs?
@@GraphicallyChallenged How to find the 3d vcache, which one do i change same as yours the Cores 8
this is cool, but what about linux? ive never seen if this issue exists on there and if it can be fixed in the same way
What's the option called on Asrock motherboards?
This is so goofy.
Just set frequency to preferred CCD in bios so all OS and apps go there, then Process Lasso your game to V-cache CCD.
Now you've got an 8 core v-cache chip completely used for the game only, and it's a better bin and higher clock than a 7800x3d 8 core, but you also have a completely separate frequency CCD to handle literally everything else.
You'd get even better than 23%. Guarantee it. Cause it's less cluttered CCD's
Can you simply explain how to do so..?
I have a asus x670e plus mobo
Anti cheats won't let you do this
@@IShaderI Set Steam or game launcher platform affinity to the same V-cache. All apps and anticheats launch there now. If not, set the affinity for that too.
Valorant probably won't work but I refuse to ever run Valorant anyway since the anticheat genuinely slows some computers - including my normally mega-snappy machine - to a crawl.
could you not achieve the same effect by setting core affinities in task manager?
for every game all the time?
better with a tool like Process Lasso
this doesnt work for me, if i do this, nothing happens when i game
This is not the right solution because for tasks where you want the CDD1 you will be limited. The right way to do it is to find a bios setting that allows you to let the drivers take care of it. Then you do a windows clean install and reinstall the chipset drivers and bam games will prioritize CCD0. Another way of doing it is to set it manually. Either way you want a solution where you can easily use both CCDs to their fullest potential. It doesn’t make sense to me to buy a 16 core processor only to limit 8 cores so you can use the other 8 with the 3dv cache for gaming. Might as well downsize to a 7800x3d.
Can I remove the Game Bar if I do this?
where can i find this in msi x670e mobo ?
Hi, what about, insted of put 3d core so low, put arround 5300, and do the same with normal cores?
can you help me with me 7900x3d? i also have asus mobo, witch cores i need to limit :P
You found any solutions??
@@dr.hannibal8338 nop, you? I just use everything on auto
0-5 5250 and 6-11 to 5050
I want to get more information on this issue.
Have you updated your chipset drivers along with updating the Game Bar using the Microsoft Store? Are you using a custom Windows image or a vanilla Windows installation?
Yes. W11 latest build.
@@GraphicallyChallenged so going into Game Bar and clicking the “remember this is a game” box while the game is in the active window not working properly?
@@Kindachi08 The fact that Game Bar is even involved in this is pure insanity. Downclocking the cores is the obvious solution to never deal with this garbage.
Actually to make the point clearly. A normal user will never know that this is even a thing, so they will always have degraded performance. Designing a product in a way that only experienced users who care about hardware topics get the advertised performance is stupid. AMD should never have done it this way, what a way to ruin a perfectly good CPU.
@@farminglolits not the amds fault entirely. windows choses which core to utilize. windows is in favor of intel it seems
process lasso?
thanks for the video .. what i saw is an overclock but what about undervolting ? any expert here to enlighten us ?
Yes, I can help.
Discord or Reddit
Well, that's certainly a unique way to try and force the auto affinity to work better in this case. But what about games that don't scale at all from more cache? This "fix" will either do nothing (if they already ran on the cores with more cache, which isn't optimal) or significantly reduce performance. (if they correctly ran on the cores without extra cache)
i don't think "significantly" is the right word.
You can probably do that same with Ryzen Master and switch between profiles in that depending on what game you're playing.
