View Full Version : Realbench OpenCL ERROR: clGetPlatformIDs

Just tried Realbench on my brand new AMD Ryzen 7 3700X system and it consistently gives an error:

KSamples/sec: OpenCL ERROR: clGetPlatformIDs(-1001)

Any ideas?

RAM: - 16GB -
MB: - FW:P3.10 -
OS:Windows 10 Home

Try this as it worked for me. Make sure you have a copy of OpenCL.dll in C:\Windows\system32. If not, follow the instructions below to see if you have one locally.

Basically, do a search for OpenCL.dll in C:\, hopefully you'll see at least one match in the driver directory or even in oldwindows dirs, if so, just copy one from the driver directory and past it into the C:\Windows\system32 and you should be good to go. I picked one that had 4 - 500K size.
