Two cards: Superoverclock 580 and Gigabyte OC Winforce 580
When I SLI them, on a 1050W Corsair PSU, Heaven max frame rate is 60
WHen I run either card on it's own, max frame rate is 125 odd
What could be causing this? Any ideas lads, I'm stumped.

Check that when it goes into SLI there isn't some random setting for Vsync (as this would probably cut down on stutter), but would limit frames to 60fps.

I've checked, and Vsync is already disabled in nvidia control panel and also in the application itself.

Since my last post ive deternined it was msi afterburner doing something to the clocks on the cards which made them massively underperform. However, now im stuck in the situation where i dont have anything to monitor temps in an osd and stuck for changing voltages. any ideas lads?

Why don't you use HWMonitor or the OC3D HWMonitor to check GPU temps and voltages?

I thought HW Monitor only did CPU temps.
Just had a thought while I was doing a job at work. I wonder if the problem has been caused by having the faster card in the primary slot? Theoretically, the slower card should be clocked up to the speed of the superoverclock but if the stock voltage isn't enough then it would crash (which I have been observing)
It wouldn't cause horrible performance (well, logically, it shouldn't do) but until I've run the slower card in the primary slot, I can't rule that out.
Will try tonight.

It shows GPU temps/voltages as well.

Does it have an OSD so you can watch in game like afterburner does?

It doesn't as far as I know.
