plan A: if you haven't specified a session name, the default would be "hashcat". therefore, you only need to call ./hashcat64.bin --restore not even need to specify the session name if it was defaul...

Post: RE: GPU high temperature. How to decrease it?

1) Get some strong fans (e.g. ULTRA KAZE DFS123812H-3000 is strong) 2) Consider watercooling (expensive though). 3) cudaHashcat offers -w 1, -w 3 etc. options but i guess this won't help much. 4) Red...

Another DIY alternative is to use e.g. ASrock BTC series mainboard and connect 6 GPUs via cheap PCIe riser cables. Bitcoin miners often do this. This mobo can drive 6 GPUs for a very low price (~65 $)...
