Zotac GTX 570 AMP's overclocking questions.

post #1 of 3
Thread Starter 
I got 2 570's with fan in middle running in sli.
I have them both oc'd to 850/1700/2000 voltage at .988.
When I run Heaven I get through it fine, but it seems that the SLI doesn't really work with it and my scores are not what they should be with SLI.
Am I doing something wrong with the setup?
Another thing is when I try to move the memory clock up (2000 is stock OC), My Kombuster and Heaven scores get worse. I even went up to 1.0 on voltage and still did the same thing. I'm stable at 850 with both in SLI, ran Furmark for 2 hours with no artifacts. Temps on GPU 1 around 85C with fan speed to match. GPU 2 got to 70 fans at 70%. Running on a Coolermaster silent pro gold 1200w.
Thanks in advance.

have you tried checking your MSI afterburner to see if both GPUs are fully loaded?

Use nvidia latest driver for better SLI performance.
