ERROR: clCreateContext(): CL_UNKNOWN_ERROR - oebb - 11-14-2019
Hi guys,
trying to run hashcat on Windows Server 2019 but getting always the same error when doing benchmarks.
I tried several versions of hashcat (5.1.0, 3.1.0, latest beta) and different drivers from nvidia. Followed the documentation on hashcat.net/wiki/, no luck.
Code:
OpenCL Platform #1: NVIDIA Corporation

try this: https://hashcat.net/faq/wrongdriver
it's probably a driver/setup problem
does this happen with all hash types and also with just "hashcat -I" and "hashcat -b" ?
another test could be to use https://hashcat.net/beta (but it probably wont help here much, because this seems like an install/configure problem of your drivers)

Thanks for your help. I already tried everything you mentioned, it still comes up with the same error message every time.
As you said, it's probably some issue with the driver but I already tried many different ones.

what about the test with the beta version ?
... and what about the test with other hash types or with -I or -b only ?

I still get:
ERROR: clCreateContext(): CL_UNKNOWN_ERROR
