Asus A8R32-MVP Issues

I dunno if anyone cares about this board anymore, but I'm wondering if anyone has problems when using the vcore over-voltage setting of +200mv? Whenever I have it enabled, my system shuts down completely, sometimes after a short time (maybe half an hour), sometimes after a few hours of being on. Even with little or no overclock. With o/c via multiplier, I know my CPU can do 2.9 (can't quite do 3.0, curse you core #2!), but even with as little as 2.7 it shuts down if the +200mv is enabled. If I have no overvolt or the +100mv setting, I'm perfectly fine, but I can't hit 2.9 at those volts, I need at least 1.5v and the max with +100mv is about 1.49v. So I'm wondering if this is a problem for anyone els. Thanks.
