Re: SLI Overclock

Simple question, have you tried increasing the voltage?

You can't increase the voltage to really dangerous levels, so there's no need to be concerned. Start with a core voltage of 1000mV and increase the AUX voltage to around half way. You can leave the Memory Voltage while OCing the core and come back to it when you start on the RAM. When you hit a frequency limit, you can either choose to stop there or increase voltage another notch and try again.

Disconnection warnings (also happens with Vantage) can be due to not enough GPU Core voltage. Unless your PSU is failing, you have plenty of power.

Also note that going from 825MHz to 850MHz offers very little benefit. Sure, FPS will rise, but you're not going to suddenly get playable frame rates in a game that was unplayable at a 25MHz lower clock.
