12 GPU hashcat rig
#1
Has anyone seen this?  It has been created for the mining community.  It seems to be that it could also serve the hashcat community.

What is the current conventional wisdom regarding the use of risers these days with hashcat?  I seem to remember reading in these forums a couple years ago that using risers with GPUs for use with hashcat wasn't optimal or recommended.

(Nevermind that the GPU market is in a shambles right now.)

The best GPU for hashcracking is the 1080Ti. You can build a machine with 8 of these GPUs with a server chassis and PSUs for ~12K. It does not make much sense to save a few bucks with an amateur mobo that brings you into trouble in cause of multiple PSUs and a complicated setup housing 12 GPUs.

Here is my setup.....8 X 1080ti with 4 PSU and dual Xeons in a rack mounted server case.

Looks like a Supermicro 4028GR-TR or similar to me.

I ended up burning up our last cracking rig built in a 4U case.  This time we went with and expandable mining rack.

I like how the cards are spaced out in this configuration...tons of airflow.
