Hashcat not using 100% of GPU

[hjsgsabsa]

Hi, I'm running the latest version of the hashcat built from github. When running crack of SHA1 I use

hashcat -a0 -m 100 pass.txt ../rockyou2021.txt  -d 3,4 -o cracked_test_db_with_rockyou.txt -w 3

From nvidia-smi it seems that only 1.7GiB out of 8192 (Nvidia Geforce) and 1.7GiB out of 16376 (Nvidia RTX A4000) is used. CUDA version is 11.7, driver version is 515.86.01.

Could please anyone suggest why so?

No more memory is needed for this attack, your GPU's CUDA cores count in the hashcat.
