Hooked up a 2'nd psu for the 2'nd card and the issue seems to have disappeared smile.gif

These cards drain so much juice !!!!

I got a kill-a-watt and my rig doesn't pull more than 750w at those speeds while benching. It must be crashing for some other reason.

The rm850 has plenty of amps on the single rail, pulling 750w from the wall the psu should barely be breaking a sweat.

Cpu & memory are all stable? If temps were all in check only thing that comes to mind is a possible stability issue.

I tried it at stock cpu and ram, still happens. (also do you think timing or mhz is more important for valley?)

You got further than me. My card runs just fine up until I try to really start going over 1.4 volts. Valley just instantly crashes then. Keep us posted. I just have a single card and a 1300 watt EVGA psu. I can't believe that it would be a power issue. I can't really get the artifacts to go away in benches if I try to go over 1450 anyway. Good luck to ya.

Why is your vrm so high? Mine never goes above 50. Usually sits at 48-49 under heavy loads like firestriker etc..
