Hello.

My AMD GPU 7900 XTX with current Windows 11 24H2 and Adrenalin 25.8.1 can not calculate the current TF 0.46 tasks.
(I disabled the internal iGPU of the 9800X3D getting TF tasks via cc_config.xml ).

Current Error Message from Stderr e.g. https://srbase.my-firewall.org/sr5/result.php?resultid=30596616:

<core_client_version>8.2.4</core_client_version>
<![CDATA[
<message>
Das Betriebssystem kann (null) nicht ausf�hren.

<stderr_txt>

In an old thread for the TF 0.44 tasks, it helped to restart the PC. But currently it doesn´t. ( https://srbase.my-firewall.org/sr5//forum_thread.php?id=1919&postid=10401 )



Then found more infos in the protocolls e.g. https://srbase.my-firewall.org/sr5/result.php?resultid=30596616


The Mfakto.ini is on AUTO and the error message says = unknown GPU = GCN.
But it is RDNA3.

"...Select device - Get device info:

I edited the mfakto.ini to GPUType=RDNA3 in the ini and rezipped it to mfakto-win-v13.zip again. But the zip file size was different => a new standard mfakto-win-v13.zip with Standard mfakto.ini was downloaded ;)

Hmmh.

Does anyone have a account on http://www.mersenneforum.org/ ?

Please post the device name "gfx1036 (Advanced Micro Devices, Inc.)" to http://www.mersenneforum.org/showthread.php?t=15646 to have it added to mfakto.

Or would it help, that the SRBASE Team updates the mfakto-win-v13.zip ?

You can change a setting in the cc_config.xml to ignore file sizes. This will prevent the server from resending the default mfakto.ini file to you again so you can use your modified file.

Change <dont_check_file_sizes>0</dont_check_file_sizes>

to

<dont_check_file_sizes>1</dont_check_file_sizes>

and save the file and restart BOINC.

Thank you Keith. Will try that workaround later.

For rebirther the current cc_config / i just added the exclude gpu things at the end. For Asteriods and Einstein it is working = no tasks for the iGpu of the 9800X3d and just task for GPU 1 = 7900 XTX are calculated:

So i then maybe can try the GPUType=RDNA in the modified mfakto.ini if it is the iGPU (RDNA2 based)?

Thanks Rebirther and Henry.

General: I uninstalled AMD Adrenalin 25.8.1 and used DDU and reinstalled 25.8.1 -> now in Taskmanager the iGPU (RDNA2) is GPU 0. And the dGPU (7900XTX) is GPU 1.

This matches with the also checked stdoutdae.txt ->

1.
Because of the newly edited cc_config setting (<ignore_ati_dev>0</ignore_ati_dev>) the iGPU = device 0 should be ignored.
But if i start two SRBASE TF v0.46 tasks, it only uses the GPU 0... can also see it in Taskmanager: GPU0 is working and GPU1 has nothing... task 2 is waiting.





2.Then i tried different device number = <ignore_ati_dev>0</ignore_ati_dev> & <ignore_ati_dev>1</ignore_ati_dev> = still GPU 0 is used...


3. AND I cannot deactivate GPU 0 because the Monitor is connected to it.


I tried with MS Copilot to find the right settings... because in client_state.xml the 7900 XTX is the only <coproc_ati> with automatically set <target>0</target> .
The idea is to change the cc_config.xml to <use_all_gpus>1</use_all_gpus> = not block the only detected one...


But for now i have to sleep a bit... will test and try tomorrow or weekend...

CU

short update: i was not able to get the TF tasks run on the "2nd" dGPU (7900 XTX) with my current iGPU to Monitor connection. They just run on the iGPU from the CPU.

I will now get a "display port to display port extension" because of the current case and the circumstances under my desk and then i can connect the vertical mounted dGPU with the current display port cable & monitor.
Then the 7900 XTX will be the primary GPU and i can disable the iGPU in UEFI.

My System is running now with just 1 GPU and no cc_config = so the dGPU 7900 XTX can crunch. (also disabled iGPU from the 9800X3D in UEFI)

-> the first 3 TF 0.46 tasks are done.
