Unstable OpenCL driver detected! - scriptkiddy - 08-21-2021 I have Intel UHD Graphics 620 graphic card and i am using windows 10 20H2 version I downloaded "OpenCL Runtime for Intel Core and Intel Xeon Processors" and in addition with this i also downloaded "Intel graphic runtime for OpenCL" and read almost 10-20 solutions on the web struggled for more than 5 hours at a time. Struggling to find solution from last 2-3 days but nothing worked for me yet thats why am posting it here please help me. Whenever i use hashcat it says unstable OpenCL driver detected . I also read the hashcat 'wrong driver' thread uninstalled all drivers and installed them again but that too not worked for me. It uses only my CPU to crack pass and thats very very much slow about 8k H/s. when i use command Hashcat -I it give following result * Device #1: Unstable OpenCL driver detected!

Intel GPUs are crap and their OpenCL runtime for GPU is even worse.

If i'm right i wanna ask that, Is this the only way to solve this problem?? Actually i have laptop, and if i go with your solution i have to change my laptop. For me i think this solution is very expensive, please help me if you have any other way to solve this problem by any software change or something like that, it will be very appreciable.

Intel GPUs are crap and their OpenCL runtime for GPU is even worse. laptops are quite not "made" for cracking, maybe if there is a dedicated GPU built in, like in gaming laptops, but not with integrated gpus you have no "real" GPU Power, so if, you have to stick to CPU (option -D 1) for cracking and see your hashrates there what type of hash (mode ?) are you trying to crack?

Actually, In task manager i found a gpu section in performance tab their was written intel UHD graphics 4 gb i wanna use that 4 gb gpu together with my 8 gb cpu to crack hashes. Whenever i use the command -D 1,2 it skips my gpu saying unstable opencl driver detected and when i use --force command it uses my gpu and cpu both but the overall speed of hash cracking decreases. My pc's hash cracking speed is about 8k-9k H/s but i think other pcs with same specs have about 120 kH/s. RE: Unstable OpenCL driver detected! - epixoip - 08-27-2021 Again, you need to uninstall the Intel graphics runtime and stick to CPU cracking only. The Intel graphics runtime is broken, you cannot use it. I'm not saying you have to change your hardware, I'm saying you cannot use you GPU.

Means i can never use this laptop to attain 120 kH/s Thats sad........ Btw thanks for your help and support. |
