OK,
This mobo is not bad per se but it requires some getting used to for like 6 months of intensive tinkering. Whether you OC or not voltage is always an issue, in fact this is the most voltage issue ridden board I have ever come across in the last 20 years or so. There is the Vdimm limitation of course but also the wide discrepancies between voltage values set in bios and actual voltage output. For example my cpu requires about 1.40 volts to function properly however if I set CPU Voltage to Auto the resulting voltage according to most sensor reading utilities (CPUZ, Everest, Orthos, etc.) is only 1.2v which obviously leads to a plethora of annoyances if left untouched. Not a big deal we can fix this by locking CPU Voltage to 1.4v, right?
Wrong, setting CPU Voltage to 1.400 still yields less than 1.3v, a huge discrepancy that can seriously cripple one's system's ability to perform normally. In the end I had to set CPU Voltage in bios to 1.5 in order to achieve a whooping 1.38v and my CPU is now running quite hot. Of course the bios and that joke progie PC Probe tell me the values I have set in bios are the ones the system is running at but guess what all other monitoring programs disagree and so does the multimeter. Seeing this one can't help but wonder what else is undervolted on that board? If I set vdimm to the max at 1.95v what am I really getting? 1.8v? Dunno, could as well be more than 1.95v seeing that I never had any problems using 2.1v ram on this board, go figure. Mind you I can only achieve 3.2Ghz OC which may sound impressive but is actually pitiful for the 6000+ whose stock clock is 3.0Ghz. Wow, a 6% OC. Boy am I impressed.
This being said I don't think this board is utter crap because at stock clocks it works ok apart from the odd sudden shutdown that happens about twice a month, which is easy to assume is due to something being undervolted (but what? not that easy to tell when all voltage values are way off the mark). But I've seen worse, far worse. So I guess this board deserves a 4 out of 10 mostly because of low price and cool looks. However it does require some technical experience to operate it, when it shouldn't. I should have looked at the OCZ motherboard compatibility chart before purchasing this board last spring. Not only is the M2N-E conspicuously absent from the chart but there isn't even a single AM2 based Asus board on that chart.
