Thread: Help me pick a new socket 775 mobo




  1. #1

    Default Help me pick a new socket 775 mobo

    I currently have a Q9550 in an EP45-DS3R. I also have a Q6600 sitting on my desk. I'm going to put the Q6600 & EP45-DS3R in my daughter's computer.

    Therefore I need a new motherboard for my Q9550. Due to the great people here at TT, I want to stay with Gigabyte. What board should I choose? Thanks.

    I'd get a EP45-UD3P or EP45-UD3R. Get the R version if you don't require two full length PCIE slots (1 x 16x and 1 x 8x, both 8x if used simultaneously).

    The UD3 series is stable, reliable, has good compatibility with different brands and models of RAM and is probably the best OC socket 775 that Gigabyte have ever made. 500+ FSB is possible with one of these and a Quad core CPU.

    Will I have better success with my overclock?

    If your current over clock is limited by your DS3R then yes.

    Both UD3 boards are capable of over 500FSB using quad core CPU's, much more than your DS3R. nothing is guaranteed though, CPU's vary etc.

    But basically, if your Q9550 is an E0 stepping then you have a 95% chance of getting 4GHz or over. It's also quite possible to be able to run a 533FSB with DRAM at 1:1 (not that it makes any difference but hey).

    Just from a personal experience the ud3p rev 1.1 has been very very good to me. I can hit 4.5 GHz with a CPUZ validation easily and am going to try higher in the near future.

    But does that mean you will? I doubt as your trying to run 8GB memory as compared to my 4GB. What matters to me is the best performance for the buck. I would personally not hesitate to buy a ud3p rev. 1.1 in hopes of a higher overclock and I personally believe your DS3R is holding you back.

    Listen to Psycho also as he's far more knowledgeable than me on overclocking...

    I just purchased a EP45-DS3P because my Abit IP35 Pro PCI-e slot took a dump. This board is great, layout is fantastic, and booted up first time with no issues with my Q9950. I am running at 3.6 Ghz with just a few tweaks. Price and performance of this board is tough to beat.

    By the way, for those chiming in, I have rev. 1.6, what is the difference from 1.1?

    Actual differences between 1.0/1.1 and 1.6 aren't 100% clear. The 1.6 revision requires a different BIOS version where as 1.0 and 1.1 use the same file. Component layout is also slightly altered on the v1.6. It is believed that the differenc between 1.0 and 1.1 is just different NB heatsink fixings.

    I have seen slightly more OC issues on 1.6 boards than the other two versions. This may or may not reflect the facts, as the sample size is too small to know for sure.

    Hmm. I checked Newegg, they have the board but they don't state the revision.

    I will be willing to bet you get a 1.6 board from them, unless you find an open box deal. They turn over a lot of stock. Sometimes they sorce from elsewhere and get older revisions etc, but it's common to get the latest from such a big e-tailer.

    Even with a 1.6 board you wil be fine. The latest beta BIOS (perfectly safe to use if flashed with QFlash) sorts out some RAM compatibility issues.

    If you're wishing to move to DDR3 by the way, there is an EP45T-UD3P/R available. this is less popular and likely at the first revision still. Means buying new RAM, but get a good set and you can take the sticks with you to your next build. Future proofing hardly ever works, but in this case it may be worth it. DDR2 prices have nearly doubled recently (supply and demand).
