Hey guys. I have a Sapphire 7870 OC ghz edition card running at stock 1050/1250 and a Gigabyte (three fan) 7870 running at stock 1100/1200.
I have attempted to overclock these a to 1125/1300 with MSI AB with Power control raised to max 20% and mV to 1225. When I click the "K" (Kombustor) on Afterburner, both GPUS show around 97 % usage for about half a minute before crashing. Unigine Valley Benchmark at Extreme HD shows me that the second card isn't being used at all (spikes for a couple seconds when I start test, then sits at 0%).
I think these overclocks are pretty low, but then again it's really my first time OCing gpus. Anyone know why I am crashing and why Unigine is only using 1 card?
Here are some screens:
