So far with a little tweaking I'm at 4.625Ghz (125 strap X 37) @ 1.365 VCore, 2000Mhz on the memory with XMP, manually adjusted the mem voltage to 1.65. Timings are 11 11 11 30 2T. - Anyone have any luck with tighter timings and/or without having to use XMP (using 2133 GSkill Rip-z's)
Haven't run P95 or IBT yet so I don't know it's certifiably stable, but I can say that I've been able to run 3dMarksVantage as well as MW3 for a few hours on the highest settings so it's at least, somewhat stable. Realtemp reports that during 3dMarks the minimum was 30c and max was 51c. Pretty satisfied with this H100 cooler, also I did lap the CPU.
Still have a bunch more tweaking and research to do but if anyone has a Sabertooth board + 3820 and would like to share some settings or advice please feel free!
Overall I'm very happy with this rig so far.
Going from an old sata HDD to this Force 3 240GB is unreal. Boot up time for Windows7 after passing BIOS screen is about 15 seconds! Shutdown takes about 8 seconds.
