    EP45-UD3P rev's any difference?

    I was wondering if any one knows if there is any difference in the Rev's of the UD3P MB. i know there is Rev 1.0, Rev 1.1, and Rev 1.6

    is the older Rev1.0 just as good as Rev1.6? would i loose anything if i buy Rev1.0 over Rev1.6? Just wondering why there are 3 revisions to the same board. was the original not good enough?

    I had the rev 1.0 and it was a great board... one of my favorite p45 chipset motherboards. I traded the board and some ram for a i5 750 and the guy I traded with was specifically interested in and looking for rev 1.0.

    I have a rev.1.6 and it's good. I went up the 533 FSB easily, the only reason I stopped is b/c my RAM is DDR2-1066.

    I'm sure when I figure out Vtt, PLL, CPU Ref, and MCH Ref voltages I'll be able to get some good clocks.

    I have had several 1.0 and 1.1's and a couple of weeks picked up a 1.6 and it sucked real bad, I heard from a lot of people that the 1.6 is a turn for the worse, it had major RAM issues and could not get my e8600 even to 4.5 ghz

    At the OP, if you can get access to a rev 1.0 or 1.1 I will buy it, please let me know

    I wonder if that has something to do with me not being able to get my E8400 quite to 4.5GHz...I just need 5-10MHz more...

    I tried both 1.0 and 1.1 revisions boards, and the 1.0 boards always clocked better

    wow, so rev 1.0 is good. so then why the heck did gigabyte even try and came up with the new rev's? i mean if something is good, don't fix it right? I was able to get 2 Rev1.0 and 1 rev1.1 the only thing is that the rev1.0's are local, and i don't trust craigslist too much as the MB's are about a year old, and not sure how long this would last.

    I'll bet on that's why you can't

    Thumbs down Diff EP45-UD3P revs

    The 1.1 version adds some power saving features that they needed for compliance in the EU. I bet the BIOS shuts down more of the huge CPU power supply circuit when idle. I have both a 1.0 and an 1.1 but have not done any testing (and don't plan on it).

    I have done similar-ish overclocks on the two boards. I overclocked a Q9300 to 3.0 with FSB (7.5 x 400) this was stable on the 1.0 version. I overclocked a E5200 to 3.0 with mult and FSB (11 x 266) this was not stable on the 1.1 version.

    I bet the 1.6 rev has a big change of some kind, like a different Jmicron controller (just an example of a change that would make them jump numbers like that).
