tchit Is it worth it to boost memory clock from 1200 to 1300?

MSIMAX i think any driver that involves navi will have this problem as they said pl mods wont work

drmrlordx Adding to the clock throttling problem, it persists in 19.9.2

I think it is related to GPGPU activity. Thus far I've experienced the problem in:

GPUPI
Geekbench 5 (Vulkan or OpenCL)
Blender Benchmark (GPU)
Dragon Quest XI (not sure why it's happening here, but cape/clothing physics stuff may be offloaded to GPU)

Under older driver revisions, such as when I had my launch card in February, it was the RAM that would downclock to 800 MHz in GPGPU scenarios. Now it's the GPU that downclocks. RAM does not. You can never tell when this is going to happen.

I'm also wondering if some later driver revisions have stability problems at high OCs but that may be a separate issue.

@WannaBeOCer I am going to report my card's problem. Thanks for the link.

edit: agh 19.9.2 is even worse, now I get the downclocking in Superposition! I've never had this before. It does it on its own, even when I do not have the bug kick in during a GPGPU benchmark beforehand. I might have to file another report with AMD, it's worse than I thought.

Lupo91 However, it is a shame that the OC is still broken, from version 19.7.5 onwards

Whereas the VII, is still the Amd flagship

MSIMAX switched to 19.5.2 got all my overclocks back 2200 core have to test if new driver performance gains outweigh the oc loss

Jesaul 19.7.5 is still good

thomasck I'm also at 19.5.2 and it's the best driver for me. There's no optimization for some games (I don't even notice it) but OC works, there's no strange screen colours time by time, and I don't need to deal with the anti lag feature which I never know when is active or not.

Sometimes ocing breaks at 19.5.2 but is the better driver for my daily use.

tchit Very good news for me: I downgraded to 19.5.2 and now the max power limit is functioning. I did a quick test at 50% with 2000Mhz and 1210mV and it seems stable. Without raising power I was totally unable to achieve this frequency with this kind of voltage and I didn’t try lowering voltage nor increasing power limit yet. Very happy
