Yup, same boards just one has crossfire and an extra g-bit LAN iirc.

After reading all the great things from this motherBoard I decided to run and pick one up since the price is right and I need to replace my 780i cause after a year of pushing I am not impressed with it at all..I'm going to run some final tests for comparison purposes and then out it goes...

ok i am really thinking of getting that board. Thank you.

hey everyone got my Q9400 to 3.72 GHz (465x8). I cant get anything more stable and im at 1.38 Vcore in the bios. it idles at 1.36-1.37 so its at the voltage max from intel. under load this chip dips way down around 1.31.

Question is how bad is it to overvolt your chip? i need this baby to at least last till march '10.

Everyone has a different opinion on over volting. I run my E8500 over 1.4v and it is under load 24/7. I honestly have no clue how long it's going to last. If it dies, I'll just buy another one

Your idle is right at max voltage, but since it's going to be folding 24/7, you can still raise the vcore a little more to where it's at 1.36v under load

well the board has proved to be capable many times over. have your overclocking skills?
what is your setup on the EP45-UD3P?

didnt feel like reading through the whole thread...
i have a set of 1066mhz dominators lying around, anyone have success with these on this board? i checked the site and it said only xms2's

Jason_B · 05-06-09

Here is what I got to at 4.1Ghz..havent gone lower voltage wise. Question is, I cant get it to boot at 4.25 Ghz...Tried Vcore @ 1.4125, MCH @ 1.5...idk what else to change.

Not sure what some of the reference voltages do, or the termination voltages either. Ive gotten it into windows..but quickly BSoD'd me at my above voltages + some reference voltages that I dont quite remember. Ive tested Vcore at 1.4125 at 4.1Ghz and I hit about 71-72*C with prime Small FFT's
