I did the mod last week by soldering a 1kOhm VR in place of the 0 Ohm resistor. So far I have the VR cranked almost all the way and am running at 3.22v on my dimms which is exactly what my 3.3v rail is reading on my psu so its at the max until i get an adjustable psu or one with higher default rails. As far as stability goes at this voltage, the lines fluctuates only slightly and never gets down lower than 3.18, again, this may correspond to weakness and fluctuation in my 3.3v rail. My board is only about a week old so its possible that abit may have changed something in the voltage regulation circuitry that has cut down on the fluctuations OPP and others have mentioned at high vdimms.
unfortunately, this has not helped my overclock at all. I think this board is screwy if you aren't running 1:1, or if you're not dual channel. I have 1 512MB stick of OCZ EL-3700 (yes I know this stick doesn't like anything over 2.9v) that has hit DDR 480 2-6-3-2 on my it-7max 2 v.2 and I have also tested some other 256MB modules rated for DDR 400. None of them will post at the 4:5 or 3:4 ratio, regardless of voltage or timings (unless I underclock my cpu to 100mhz fsb and use the 4:5 ratio...ugh). They will also not post if i use any of the new "game accelerator" options, even the most lax ones. I remember reading another thread about an overclocking "hole" in one of the canterwood boards when using 533mhz chips, maybe this is the similar. I'd appreciate some feedback on this. If its a common problem than I'll hold on to this until i grab a new cpu and go dual channel. If not, then I need to rma.
