ROG CROSSHAIR X870E HERO and 9950X3D - Gaming Adaptive CCD Parker - Freeze/Crash

[ZeFlyingFrog]

Hi there,

Similarly to what was reported in a different post (in June/July), I am facing issues with the 9950X3D using the non-cache CCD (CCD1) instead of CCD0 (3V Cache).

I tried changing CPPC to Driver but that didn't do the trick.

I then tried to enable the Gaming Adaptive CCD Parker function in BIOS (1715). It does correctly allocate the games to CCD0 (by parking CCD1)  but after a few minutes of gaming - and much better performance -  I get increasingly longer freezes (from 1 sec to 5 sec to even longer as time goes on) to the point where the game then the PC isn't usable anymore.

When I looked at the usage of the CPU CCD0 at that moment, it looked maxed out.

I used this on the following games with the same effect:
- MSFS 2024 - SU3 Stable version
- COD BO7 Beta / BO6

Other steps taken (I have also contacted AMD about this but given there seem to be a strong similarity between someone else problem and mine, on the exact same board..)

• Enabled Gaming Adaptive CCD Parker → games correctly render on CCD0 but result in progressive freezing (1 s → 5 s → longer).

• Disabled Gaming Adaptive CCD Parker → games revert to running on CCD1.

• Changed CPPC setting:

  • AUTO → games use CCD1 (non-cache).

  • DRIVER → same behavior, CCD0 parked.

  • FREQUENCY + Installed Process Lasso Game CPU affinity/sets forced to CCD0 → initially works but causes same freezing as Parker mode after a few minutes.

• Verified amd3dvcachesvc service appears in Task Manager but remains in Stopped state. Attempting to start it (via Task Manager or Command Prompt) results in it stopping again after a few seconds.

• Tested with and without Game Mode / ReBAR — no change.

My gear

• CPU: Ryzen 9 9950X3D

• Motherboard: ASUS Crosshair X870E Hero (BIOS 1715)

• RAM: 96 GB DDR5 (2×48 GB, 6000 MHz, CL30, EXPO I)

• GPU: RTX 5090 Astral LC

• Windows 11 24H2 (latest updates)

• Latest AMD Chipset Driver installed

Could it be a firmware issue from the board?
I'd appreciate anyone's help!

Hello!
I'm using machine translation because I'm not fluent in English, so I apologize if anything sounds strange.

I own a different ASUS motherboard and am facing the same issue.

In my setup, there are games where this problem occurs and games where it doesn't.
Games where it doesn't occur:
Overwatch 2

Games where it occurs:
Apex Legends, Battlefield 6

However, I think I've pinpointed which setting change prevents this phenomenon.

BIOS\AI TWEAKER\Core Flex\Algorithm3
When enabled, this seems to be the cause of the freezes.

When you first enable Gaming Adaptive CCD Parker, Algorithm1 and Algorithm3 are enabled, and default values are written, I believe.

If I change Algorithm3 from enabled to auto, the freeze doesn't seem to occur. What do you think?

However, the default values after enabling Algorithm3 feel more responsive. I really want to find a way to keep this option enabled while playing.

Hi.  I' afraid I don't have an answer to this but I have exactly the same motherboard, GPU, CPU, RAM, and chipset driver as you and I have the same issue.  I have windows power mode on balanced, BIOS has CPPC set to driver.  Everything has been checked and I have uninstalled and installed all drivers and Ryzen master several times but it is still not working.  I'm out of ideas at the moment and will try again tomorrow but just wanted to let you know that someone else has the same issue on the same gear.

Hi @ZeFlyingFrog 

Have you tried rolling back to something like 1603 (1.2.0.3f) and seen if the behaviour is the same?

Reinstall the OS, and potentialy log the CCD temperatures using HWiNFO to ensure CCD0 isn't throttling.
