Threadripper not found

[Sondero]

Hello,
i got my new workstation, Threadripper 3970x + RTX2080TI.

I would test the CPU (GPU works fine) but get this error-log:

hashcat.exe -b -D1
hashcat (v6.0.0) 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: CUDA SDK Toolkit installation NOT detected.

I think the CUDA-driver is only for the GPU, so are there drivers that hashcat will accept my CPU too ?
