Hi all.
Yesterday I encountered some strange problems with Realbench and GPU together.
First, MSI Afterburner stopped recognizing my GPU completely—this happened while I was using the PC.
I attempted to remove drivers via DDU (also from safemode) and reinstall them. That fixed the Afterburner issue by installing the latest GPU driver.
Later, during a stresstest in Realbench, I encountered an error in Luxmark. The message displayed was "OpenCL Error: clBuildProgram(-9999)" within the text field.
The CPU benchmark ran normally, but the Luxmark part didn’t respond.
I tried these steps:
- Reinstall GPU drivers
- Reseat the GPU
- Reinstall Realbench
- Ran "sfc /scannow" – it repaired corrupted files successfully
I’m unsure what to do next and would appreciate any guidance.
Thanks in advance.

It might be time to reinstall Windows 10.
My system is behaving oddly since all this overclocking :'D.
I've tried the GPU drivers five times now, and this time I installed the latest one (the previous one didn't work with Afterburner). It seems to have resolved the Realbench problem and Afterburner now recognizes my GPU.
Could it be that the "sfc /scannow" scan fixed the corrupted files and solved the issue?
Also, after completing the sfc scan, are there any further steps needed to repair those corrupted files, or is the process complete?
