Thanks for replies. My temps are fine at 60c.
Also I'm using simple miner. This is my 4th rig and I've never experienced this. All my others seen fine. Any other ideas that I can check?

I would first think it's a power problem.
1) Check 12 volt under load with a multimeter and see if it sags under 11.88 volts. If so, you are probably overloading your power supply and need a bigger better one.
2) If it's AMD, then undervolt the GPU core by 100mV. Increase powerlimit.
Second, make sure pool ping times are 200ms or below, and a constant connection. Check your gpu usage % in gpu-z or a CPUID HWMONITOR software. I am assuming you are running windows. If gpu usage % is fluctuating, it may be due to the pool not giving you enough work fast enough. You can fix this by increasing the share difficulty with your pool. Most of them do this automatically with VARDIFF when you are connected to their VARDIFF port or if they always use VARDIFF. Sometimes it doesn't adjust appropriately to your hashrate.
