Got it stable at 1600 x8 (3200mhz) with 1.4v in BIOS and loadline off. The highest I can get it is 3420 mhz (1520fsb) with 1.475vcore. But I have been notified that the ASUS PC Probe II readings are due to electromigration. I lowered vcore so that BIOS reported less than 1.5v, and PC Probe II behaved itself nicely.

The max I want to run this cpu is 3.2ghz 24/7. It is not worth it pushing so many volts just to gain 200 mhz. RAM is supposed to be warranted up to 2v, but I am not going to bother clocking them. Seeing that I've got 1600 fsb stable, I thought I might invest in some 1600 mhz RAM. I'm looking for 4gb (2 x 2gb) is there any good kits that anyone recommends on this board? Which are known to be stable with 1600 fsb?
