RTX4090 Loops and Thrust
#1
hello - when running
Code:
hashcat -b -m 610
on a RTX4090 i get 

Code:
Loops: 1024 Thrust: 256 Vec: 1

A friend gets,

Code:
Loops: 512 Thrust: 512 Vec: 1 

and seems to get better performance.

So,
1 Is a lower loops score better?
2 If 1 is yes, how can I get this score?
3 Is high Thrust score better
4 If 3 is yes how I can get that score?

I am running Cuda 12.3.68, but only the drivers. Would installing the SDK make a difference?

Thank you

Thr stands for "Threads", not "Thrust". Also, that's a perfectly acceptable hashrate. The "12966.1 MH/s" number is all that matters, the additional tuning settings (Accel, Loops etc) don't really mean anything practically speaking. Installing the CUDA Toolkit can help a bit but is usually margin of error. For reference, you have 99.19% less hashrate than this reference point:

So there's really nothing to worry about for speed Smile
