Nwalm Posted February 24, 2020 Share Posted February 24, 2020 (edited) 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).

_mat_ Posted February 24, 2020 Share Posted February 24, 2020 There is a log file called GPUPI.log. Can you upload it here? Quote Link to comment Share on other sites More sharing options...
Nwalm Posted February 24, 2020 Author Share Posted February 24, 2020 I dont find it, when i click Debug log i get this : LOG START at 2020-02-24 09:52:13 ---------------------- HWiNFO library for extended hardware detection successfully loaded.

_mat_ Posted February 24, 2020 Share Posted February 24, 2020 (edited) 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? Edited February 24, 2020 by _mat_ Quote Link to comment Share on other sites More sharing options...
Nwalm Posted February 24, 2020 Author Share Posted February 24, 2020 Yes i can bench the GPU (Vega 8 aka gfx902), but not the CPU (2200G). Quote Link to comment Share on other sites More sharing options...
_mat_ Posted February 24, 2020 Share Posted February 24, 2020 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: 2 Quote Link to comment Share on other sites More sharing options...
Nwalm Posted February 24, 2020 Author Share Posted February 24, 2020 Yep i have only amdocl64.dll listed in the registry. I will try without the video drivers. Thanks for your fast answer Quote Link to comment Share on other sites More sharing options...
Nwalm Posted February 24, 2020 Author Share Posted February 24, 2020 (edited) [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.

Nwalm Posted February 24, 2020 Author Share Posted February 24, 2020 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.

Nwalm Posted February 24, 2020 Author Share Posted February 24, 2020 Just to be thorough here just after removing the video driver again, didnt touch anything else : Quote Link to comment Share on other sites More sharing options...

But when the video driver is installed only the GPU one is detected. 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. ? Edited February 24, 2020 by _mat_ 1 Quote Link to comment Share on other sites More sharing options...
