I just wonderd if you guys could help me, i brought a KFA2 570 from scan about 2 weeks ago and yesterday i started getting white dots flying around on my screen when i watch any kind of video, also when playing games and on my desktop, i have emailed scan for a return today, but a friend said to me it maybe your mobo overclock. i was thinking i may need to change the voltages in bold? what do you guys think!

Your PCIe frequency is locked at 100MHz, so your BCLK overclock doesn't affect the video card's clock. You probably have a card with memory problems, try underclocking it for a bit, and see how it goes.

I would put IOH core to 1.16V, IOH PCIe to 1.56V, ICH core to 1.1V (default), ICH PCIe to 1.5V (default). Overvolting the IOH PCIe even more is only needed if you have a lot of expansion cards on the NB PCIe lanes, apart from the 570 that is.

AUTO is not the same with DEFAULT/NORMAL. The AUTO setting usually overvolts a lot more then needed when BCLK is in manual mode (unlocked and over 133MHz), I would stay away from it. AUTO is default ONLY when overclocking is disabled.
