Hello!

So like i said in the title i cant find a way to bench the CPU part of these APU with GPUPI (tested with 2200G and 3000G). They are simply not recognised as OpenCL device.

Windows 10 Pro, with chipset drivers and Adrenalin 20.1.3. I installed both AMD APP SDK provided by mat on the GPUPI support thread. Did i forget something ? (no issue on my old 2600K).

There is a log file called GPUPI.log. Can you upload it here?

I dont find it, when i click Debug log i get this :

LOG START at 2020-02-24 09:52:13 ----------------------

The log says you should have the APU as "gfx902" in the "OpenCL GPU devices" node in the settings dialog. Is that not the case?

Yes i can bench the GPU (Vega 8 aka gfx902), but not the CPU (2200G).

I read your post to quickly, sorry.

This seems to be the AMD driver bug where the GPU driver overwrites the registry entries that the AMD APP SDK previously added. Have a look at the following post at the answer to StingerYar: 

 

Yep i have only amdocl64.dll listed in the registry.

I will try without the video drivers. Thanks for your fast answer

[edit] nop talked to fast, that didnt work.

Actually as long as the video driver is not installed it work and i can install multiple version by adding then in the registry. But when the video driver is installed only the GPU one is detected.

Here a screen. With this registry edit if i remove the driver both 1.2 and 2.0 versions are selectable in GPUPI, and with the video driver installed like in this screen that didnt work anymore.

Just to be thorough here just after removing the video driver again, didnt touch anything else :

That's exactly the problem, the GPU driver overwrites these entries. It boggles my mind why AMD would do anything like that. Shows how much they care about their OpenCL CPU implementation. ?
