GPU utilization oscillates when cracking a rar3-p hash
#1
I am trying to crack a rar3-p (-m 23800) hash using a dictionary:

hashcat.exe -a 0 -O -w 3 -m 23800 hashfile.txt dictionary_file.txt -o results.txt

My GPU is a RX 6600, installed in a x16 slot.

The GPU utilization (as reported by both hashcat itself and AMD tools) jumps between 0% and 99% with a period of 4-ish seconds. Average utilization seems to be close to 60%. Every once in a while I see several seconds with full utilization.

What might be going on here? I understand that rar3-p is considered to be a "slow" hash and a dictionary attack with no amplification is appropriate. Or am I wrong?

Thanks!
