AMD Core-Parking problems FIXED once and for all!

After dealing with frustrating issued regarding Core Parking on the 7900X3D and 7950X3D I discovered two easy solutions to help resolve this issue without the need for reinstalling Windows... which is the official "AMD recommended solution" which is AWFUL... Hopefully this helps.

The amount of people asking me if this applies to their non X3D CPU or their 5800X3D or 7800X3D has me a little concerned. I know I mentioned that this only applies to 7900X3D and 7950X3D or any future multi CCD X3D CPUs but I'm realizing that many people don't really understand how their AMD CPUs are arranged internally.

This is one of the many reasons chiplet designs are so confusing to those who don't care or follow this sort of material.

So short answer is no; this doesn't affect you if you don't a 7900X3D or 7950X3D.

As annoying as this was for him, I guarantee that Jay enjoys solving problems like this 1000 times more than actually playing the game. 😅

The fact that Jay didn’t yell “Parkour!” and jump over a desk was a missed opportunity 😆

Actually, when using Revo Uninstaller, you can do the restart when prompted. After the computer reboots, open Revo again. It will ask if you want to finish removing the stray folders, files, and registry entries from the uninstall that was being done prior to the restart. I find it better this way, because the left over components are freed up from being used by the system because the program or drivers are no longer there to use them.

Clear, concise, spot on job. Thank you for diving into this topic.

You used the live example, drove the machine through the steps, this is what separates a good teacher from a bad one.

Thank you so much for sharing with clear execution.

My desk has less dents as a result of not banging my head off it.

Jay, thank you so much for this perfectly timed video. I literally purchased the 7950X3D yesterday after seeing your video on the new 9900X/9950X benchmarks.

For me, Diablo 4 went up from 122 FPS to 128, but Dragons Dogma 2 went down from 92 FPS to 82 FPS. I was about to send it back and get the 9950X, but I saw this video and realized my cores are not parking. Thank you so much!

These issues are the reason I was not even considering a dual ccd x3d CPU. Nice work Jay and company!

I don't have a 3D V-Cache CPU, but I still think that this is an EXCELLENT video as it probably prescribes a procedure that is easy and simple for people to follow, so that they can FINALLY realise the full potential of the CPU that they ACTUALLY purchased.

[LastKnight]

Hey Jay! As the owner of a 9900X3D your tech advice really helped me eek a bit more out of it. Ran it in the driver mode and this now makes my games much smoothe!

Thanks again and I really really appreciate your tech tip videos - as an IT professional who does want to get into the home PC performance tuning - this really helps.

So... If this fix is legit, shouldn't reviewers re review all x3d chips and compare with 7800x3d? I suspect 7900x3d and 7950x3d would have improved or hidden performance, maybe better... If they aren't already...

[SealedSun]

I love the 7950X3D. Just such a powerful and interesting CPU, engineering-wise. But you really have to know all of this stuff to use it properly. AMD won't tell you any of this. There is no leaflet in the CPU box "here is how to get the most out of your CPU". Nothing. If you don't know about the magical incantations, you just wasted a bunch of money.

[ExpGames]

For games that dont seem to use only the x3d chip. Do this.

1:Launch your game / app
2: Open gamebar (win+g)
3: Go in settings, Toggle ON Remember this is a game.

Thats it.
(If it doesnt work just click out of the game and back in.)

0 need to mess around in bios, unlike intel. Leave it alone.

[Infinitiverse]

Thank you for this video, it helped me with my 7950X3D getting core parking to work after a fresh install the revo Uninstaller method + enabling Driver mode in the BIOS worked when everything else didn't. I also disabled my MSI motherboard's odd feature to 'slip' the drivers into a Windows update service, not sure if that also made a difference for me but the result is my core parking is working now.

[StngerGuy]

The bios setting fixed my 9950X3D :) I had the service running already but it wasn't using the right cores. Thanks for this vid!

[ShiroXetas]

Thanks Jay! Recently upgraded to 7950x3d and my ASRock B650e Taichi board was set to Auto for CPPC on the latest Bios at the time of writing this which is 3.06. I did a fresh install so didn't have to worry about the driver reinstall part. Hope this goes viral to raise awareness for others.

[Dan-Simms]

And this is why the 7800x3D is the gaming king, no headache with only 1CCD

[gbona]

Great gains on Counter Strike 2

FPS: Avg=555.3, P1=255 - Before Fix
FPS: Avg=621.3, P1=286.7 - After Fix

[glockss]

Brother, you saved me. I thought I bought some bootleg 9800x3d because my performances was just horrible. Turns out selecting Balanced instead of High Performance power mode fixed the issue that easy. I was struggling for days trying to figure this out. THANK YOU!

[MeticulousTechTV]

DUDEEEE!!! I can't believe that CPPC -> Driver isn't the default setting, unreal! I've been dealing with constant crashing in CPU intensive tasks since getting my 9950X3D on launch day, and finally, finally, FINALLY this resolved it! I noticed my cores would all do some whacky attempt at parking out of order right when the crash occurred, and it lead me this video.

OMG reformatted my PC, hardware changes, was pulling my hair out and ready to start warrantying my CPU. SO HAPPY!

Edit: MSI X870 Carbon, latest BIOS and chipset drivers

[SmeltBlock]

9950x3d just came out and you helped me a lot ! I didn’t like or comment a video since years but you deserve this
