Overclocking 2x 6970's help

post #1 of 2
Thread Starter 
Hey this will be my first time overclocking graphics cards and i wouldn't know where to begin.
Ive read that u will need "combustor" to test for artifacts that i understand, but how do i know that at the desired clock speed, ive got enough voltage?
When would i know that its time to up the volts?
Im after 950 coreclock and 1450 memory on both cards.
Any tips would be very helpfull.

Read the overclocking guide at the top of the ati/amd graphics cards forum in the sticky section,i would type it out but I'm on my phone lol, hope this helps.

Also I would use furmark instead of kombuster, I believe it gets the cards hotter and more throughly tests the cards
