I have the original IT7 (version 1). I am running the OEM BIOS (think it is April 2002). I find that the VDIMM doesn't seem to work over 2.8 volts. If I increase it, I get the same or more #5/#6 errors.
It's not the DDR as a stick of Corsair XMS3500 C2 has done DDR466, 2-3-2-6 (2.8 volts) and DDR472, 2-2-2-5 (3.0 volts) on other boards. It maxes out at DDR445, 2-3-3-7 at 2.8 volts on the IT7. Regardless of whether I relax timings or increase voltage to 3.2, it won't go over DDR445. I get the same amount of #5/#6 errors in Memtest.
Is the problem the BIOS?
I'm using a 400 watt Sparkle power supply with pots bumped, same unit that got me to those lofty DDR settings on a PX845PEV PRO and 4PEA+, so the board has enough juice.
