    Default Can a GA-EP45-UD3P Take DDR3 ? Anyone doing it?

    I was looking over the memory compatibility list and it had a notation saying "overclock to DDR3"

    Then I looked at the spec sheet and seen the below text. I take it it will work but I have to do some BIOS tweaking? Thanks


    1. 4 x 1.8V DDR2 DIMM sockets supporting up to 16 GB of system memory
    2. Dual channel memory architecture
    3. Support for DDR2 1366+*/1066/800/667 MHz memory modules

    * Refer to Memory Support List for more information.

    Nio, the EP45-UD3P is DDR2 only, it's the EP45T-UD3P that uses DDR3.

    You won't even be able to install DDR3 in the board, as the slots are keyed differently.

    Ah! Shows you how far I am behind. They do indicate it can be clocked to DDR3 speed but I'll avoid that.

    I've never seen anywhere, either in printed literature or ion any websites the mention of DDR3 with the EP45-UD3P. Maybe it's a misprint or mistake on the site/in the literature?

    Definitely not possible to clock DDR much beyond 1200MHz without a lot of tweaking. I'm sure people have hit higher with extreme cooling and perfect sticks, but I'm sure there would be no intentional claim to reach those speeds without it being a mistake.

    The text in my OP with lines 1,2,3 and the asterisk are copied and pasted from the Gigabyte webbsite page on the UD3P memory compatibility page or the spec page. They are talking clocking, not hardware I guess.

    Thanks

    That is refering to DDR2 using a 333 FSB and a 4.0 multiplier which is just under 1366. Why they quote 1366 I don't kow, as it's actually 1333. In other words it's a speed that is natively supported with a RAM multiplier and not requiring you to OC the FSB to get there.

    Thank you.

    I'm looking at it because I have 4x2GB sticks in my system (see sig) and want to upgrade the RAM taking them out to another board (GA-EP35-DS3R) I have laying about the work bench.
    I also want to do the same with my Q6600 replacing it with a Q9550 or Q9650.

    So I'm looking for optimum RAM to slap back into the UD3P. Kind of an upgrade/refreshing thing.
