Using my hardware correctly? - Marcolator - 07-21-2021
Hello
After trying to update drivers etc. i went from ~500 H/s to ~40.000 H/s, but that still seems kinda low..
As far as I can see, it is only running on 1 of my GPU's and not on my CPU at all.
How can that be, am i doing something wrong or is my hardware just not strong enough?
* Device #3: Unstable OpenCL driver detected!
This OpenCL driver may fail kernel compilation or produce false negatives.
You can use --force to override, but do not report related errors.

first see https://hashcat.net/forum/thread-7717.html ,your kind of attack is considered to be outdated (mode 2500)
second, try using options -D 1,2 -O
this will tell hashcat to use CPU and GPU together with optimized kernel
third, hashrate depends on hashmode and attack, you can use
hashcat -D 1,2 -b -m 2500
to see your "very maximum speed"
example output

i think your rate is quite okay for this "old gpu"
