I think you should increase the SB volts. Its the same with the IOH on intel.
The more GPUs you have, the more stress you are putting on the SB. If it doesn't have enough volts, it will also start stressing the CPU.

I had something similar in the past, that when OCing the cards, the computer starts to BSOD on CPU errors.
There's PCI Express lanes hanging off the Southbridge on that board? Yuck.

@MS ... I cannot see how it possibly could be a bad thing to have a single GPU connected to multiple 'rails' of the PSU. Who/what told you that this was to be avoided?

Along w/the southbridge, if in fact you're using PCI-Ex lanes that are connected to it (and you might also look into whether your NB is being used for PCI-Ex lanes), I would probably also try just raising the CPU voltage a bit.

It's not terribly uncommon to end up needing more volts to your CPU when you add graphical power. I've had it happen before just from upgrading from a weaker card to a stronger card.

The ThermalTake manual for the same OEM power supply. I also noticed the Gigabyte unit colour codes the GPU power connectors red and blue, but neglect to comment why.

I don't buy that you actually need to worry about having every GPU strictly on it's own rail, no matter what the manual says. That's me personally ... I'm saying it makes no sense to me that it should matter. But if you're able to comply with this, even w/3 GPU's requiring 2 connectors each, I guess you might as well follow instructions ... but if can't, I wouldn't worry about it

I had trouble believing it, but after sorting the cabling out I am now gently overclocking at 3.7GHz, easy enough but will leave running over night to see how stable it is.
