First off, I need to get an matx board.
I just built a new i5 750 rig with the P55M-UD2, and was running prime @ 3.5ghz, 1.25 VTT, 1.33 QPI. It made this high pitched squealing noise when it was under 100% load, and after about 2 minutes, the entire computer turned off and I saw burn marks on the mosfets.
I've been doing a bit of googling, and I only found a few cases of this, so I want to know: can this board handle 24/7 1.375 VTT, 1.35 QPI? I'd like to hit 4.0ghz; maybe the UD4 would be better (but I really don't need all those extra features, and it's like $40 more).
Also: my gskill 1600 ripjaws would not do a mhz over 1600, even at stock timings and 1.64V. Could that have been because of the mobo?
