** Official ** Gigabyte UD3 P45 Series -- EP45-UD3 / EP45-UD3R / EP45-UD3P

[Zucker2k]

Stay away from the C -- Combo DDR2/DDR3 board. One can say take the UD3R over the UD3L as it has better HS's on the board components. And it has an 8 pin CPU power connector unlike the 4 pin on the UD3L. However I have a GA-EP45T-UD3LR (DDR3 version) and it only has 4 pin CPU power and I'm running it at 8x500 (see sig). I'd go for the UD3R cause of the better cooling HS.

Edit:
Oh, and BIOS is a little more cut down on the UD3L series in the M.I.T. section.

Why, is the combo board bad?

I actually find the EP45C a breeze, and but for my crappy psu and ram, as well as the fact that I'm on air, I could probably be taking down some records. I've primed as high as 4.35Ghz already and clockgened to 4.6Ghz with the settings below oc:
