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first see https://hashcat.net/forum/thread-7717.html ,your kind of attack is considered to be outdated (mode 2500)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"

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