Hello everyone. Im trying to make benchmark on CPU like this: cpu It's a notebook CPU ( i9 - 9980HK ) inserted into desktop motherboard ( mutant ). 

When i'm launching hashcat -b -m 15700 i can see: 

---------------------------
Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

How can i solve this problem ? ( force hashcat to use this cpu ) thx

P.S. Intel Processor Diagnostic Tool says: CPU 1 - BrandString - Fail.
Those kinds of CPUs can be really difficult, especially engineering samples, which that probably is. The 15700 is by far the slowest algorithm Hashcat supports so even with your CPU functioning, you won't get more than 10H/s at best. The only reason it's saying 0H/s is because it's rounding down, so it's less than 0.5H/s. It may help if you do "-D 1 -d 3" but OpenCL is crashing here, it's not a Hashcat issue, it's your environment or CPU not being happy with OpenCL
It's not sayng 0H/s. It; saying:

Like hashcat not starting benchmarking. With GPU (igpu) hashcat saying - 0 H/s.
Solved: Restored default BIOS. 31 H/s
