So NB voltage has to be increased when running SLI? I've not changed any voltages; all are running on Auto. To recap, I'm running 4gb of RAM at 588, 1:1 with my FSB. My CPU is at 294x9 (2.565 GHz). I can try tweaking the voltage on my own, but around where should I be starting? Is this a likely cause of my instability?
