Well just got my gf's 7750 BE and Biostar 790GX/SB750 in.
I tossed the 720BE on there, same results as my DFI gave me. Turn ACC on Auto and save the bios + exit. Then the comp powers off, not a restart just flat out turns off. And turning it on will only last about 3 - 4 seconds before it powers off and I have to reset the bios to go any farther. I messed with giving the 4th core diff voltage manually a bit, but no luck.
Probably a good thing either way, just looking at that board vs the DFI you can see the major difference in build quality. The Biostar is littered with caps that have the cheapo plastic outsides. And no HS on the VRM's.
But it goes beyond that, I finally got around to OC'ing the 7750 and got some pretty darn good results. As it sits right now with the stock fan on and only 1x 120mm case fan going I have it running at 3.3ghz with 1.344v. But for anyone looking to get the most out of their OC I do not recommend this board, you get what you pay for. And the vdroop is UNBELIEVABLE on this thing. First discovery was that anything from 1.375v to 1.450v resulted in a 1.408v once under load, and even then it would drop to 1.392v intermittitantly. Then under 1.375v was just flat out random, the next one down ended up being over 1.375v, then 1.350v ended up being like 1.33v, and the one under that ended up being like 1.344v... Which is where I have it sitting now, and it will still vary a bit under load. But it passed wPrime 1024 without an issue. Once I get some more fans for her case see what I can get out of it now. I just can't give it more volts, it's stable above 1.4v but it just gets too hot too fast.
