Haven't tested much yet, but four sticks seems to limit ram overclock, as expected, but not cpu overclock. Temps are high, a lot higher than I would believe under water, maybe sensors are showing too high temps. I'm thinking it's a combination of nb and general bad overclocking performance limiting me. You remember where you posted the nb fid register values in your MSI thread?
And just to be sure, nb speed could not be lower than ht link speed? Right, or was it the opposite...

Should be able to take som pics of bios..
