1  Other / CPU/GPU Bitcoin mining hardware / Erratic voltage drops? on: July 27, 2011, 06:30:31 AM
Hey guys!

Just put together another mining rig and ran into a little issue. I got everything setup and running and started to test mining on one GPU when I encountered this (Check the 12V, VDDC and VDDC Current sections)



This came with an erratic hashrate and the GPU load never hit 99%. I'm running this machine with 3x6950s with a 1000w PSU and was only attempting to hash on the first card. I had a kill-a-watt plugged in at the time, and the draw from the wall fluctuated from 279-282 watts which seemed fairly normal.

Has anyone encountered this? Or is this just a shoddy PSU?
