Is the P5ND2 SLI the deluxe version? I dont think it makes any differnece, ut thats what I have.
I have a 650 (3.4Ghz) and have mangaged to O/C to 3.95Ghz with Corsair XMS2 and Thermaltake Big Typhoon Cooling.
I wouldnt reccomend O/Cong with the stock cooler, especially on the 840.
Also, dont O/C from windows using AI Booster, it all goes wrong. Do it from the BIOS.
