CPU device not available

[f4nthomas]

Hi folks,

For some reason, my hashcat can use only GPU, CPU seems to be "not available". Hashcat does not see it within the available devices.
Do you have any clue why? My CPU isn't old (i9-9900KF), and drivers should be up-to-date. I tried to explicitly enable it along with GPU using a parameter "-D 1,2"  and also with "-d 1,2" ) for benchmarks in any combination, but without success.

Code:

[ 9:55:56] C:\hashcat-5.1.0>hashcat64.exe -m 0 -D 1,2 -b
hashcat (v5.1.0) starting in benchmark mode...

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.

* Device #1: WARNING! Kernel exec timeout is not disabled.
            This may cause "CL_OUT_OF_RESOURCES" or related errors.
            To disable the timeout, see: https://hashcat.net/q/timeoutpatch
