    Here is the setting when set to stock settings(load optimized).

    I have emailed gigabyte tech support and this is the chatlog:

    Question - 710351
    From : Chris
    Sent : 1/27/2009 08:46
    Question : I have 2 of the same motherboard, a rev 1.0 and a rev 1.1 with the exact same issue. NO matter what I do, or what kind of ram or size of the modules, I can only run 1 stick.
    If I try to install both sticks, my computer just power cycles, never getting to the bios screen. As soon as I pull a stick out and run 1 stick, it boots up perfectly. With one stick i can even OC my Q9550 to 471x8.5 on stock voltage.
    I have 5 different sets of ram I have tried:
    GSkill Pi 2x2gig ddr2-8800 5-5-5-15 1.8-1.9v
    GSkill Black Pi 2x2gig ddr2-6400 4-4-4-12 1.8-1.9v
    GSkill 2x1gig ddr2-6400 2BHZs 4-4-4-12 2.1v
    Crucial Ballistixs 2x1gig ddr2-6400 double sided modules 4-4-4-12
    Crucial Ballistixs 2x1gig ddr2-6400 single sided modules 4-4-4-12 2.2v

    All 5 sets pas memtest. All 5 sets do the same thing. 1 stick in it runs fine. both sticks in, it power cycles.
    I also have found out other people are having the same issues. You can visit http://www.xtremesystems.org/forums/...205132&page=61 and www.tweaktown.com to see others with the same issues.

    Answer : Do not perform any overclocking and leave all setting at default, are there any issue operating with more than one module at default setting?
    We are unable to guarantee any results off from overclocking

    Question : At default clocks it does not run on two modules. I thought it could be my power supply but it is not. I ahve been reading on the xtremesystem forums and tweaktown forums that others are having the exact same issue. I have a rev 1.0 and 1.1 boards with the exact same issue.

    Answer : You had also tried lowering the spec of the memory as well?
    Try testing with value ram instead of high performance memory also


    Question - 712506
    From : Chris
    Sent : 2/1/2009 06:18
    Question : I have lowered my GSkill 8800s to 800mhz speeds and nothing worked. I switched out to my 800mhz ram and it doesnt work.
    You are now suggesting I go buy value ram to try and see if it will run on a motherboard made to handles DDR1333?

    Answer - 712506
    Answer : The chipset can support up to 1333fsb, whether if your memory is fully stable at that particular spec we cannot determine. If you feel the issue is within the board you may send in for us to further examine through the below website


    Question - 713893
    From : Chris
    Sent : 2/4/2009 09:49
    Question : If I mail my board to you, are you going to try it with some ram that I have? Or are you going to use some value ram?
    I want to know this because I want to see if you can duplicate the issues I am having with my high performance ram and see if there is a solution you can figure out. Since I don't plan to use some value ram, I want to know before i waste my time and money to ship the board to you, that ya'll will look into this ram issue with some ram that is comparable to the one's I own.

    Answer - 713893
    Answer : We will test with the memory which we have on our lab, we do not have all memory on the market to test with. Since we do not have your memory we are unable to verified your memory


    From : Chris
    Sent : 2/10/2009 10:22
    Question : Are you looking into this issue, as many people are having the same issue as me? Also, any idea of a updated bios or possible beta bios I could try out?

    Answer - 716872
    Answer : This is not an known issue, since we do not have your memory we cannot determine the stability of your memory which you are using. Do try testing at an lower frequency first to see if it'll improve on stability


    Question - 717434
    From : Chris
    Sent : 2/11/2009 08:24
    Question : I have tried running it at 667mhz and it still will not run with 2 sticks of ram. I am capable of getting two sticks to run in single channel mode by using memory slots 1 and 2.

    Answer : If you feel that the issue is the board you may send in for further examination. Refer to the below link to submit your rma request

    Well I went to microcenter yesterday and bought another UD3P. Rev 1.1
    Had the guy post test it at the store with my ram, and it posted, so it took me 2 boards to get a functioning one. I would say if you wanna stick with this board , cloo then rma till you get a good one, or just return it for a refund, I dont think youll get anywhere with the bios settings.

    By now I think that your board is definitely a RMA case.
    I would seriously email someone at Anandtech and show them some links. Maybe they'll talk to someone higher up at GB who will look into this problem. This would probably reduce your RMA time (usually 4-6 weeks from what I've heard) AND make GB aware of this issue as well. So maybe there will be a future BIOS release that fixes this for the other people that have this problem.

    Well, I submitted an RMA request for this board(rev 1.0) before I even purchased the rev 1.1 and gigabyte never responded.

    Submit again, and make reference to the first RMA request. Do as nickel020 suggests and you might get somewhere this time.

    You could always become a hardware reviewer and write a few nice articles and then post about this dud of a board and post the link in as many hardware enthusiast forums as you can. In the article keep a list of all the places you have posted a link for this article to.

    Should knock their reputation a little and maybe if you create yet another RMA with a link to your article they might listen, especially if they see how many of the popular forums you have put this into. :)

    retried RMA and waiting for confirmation.
    Also, noticed the new f7a betabios. Tried it out and it did not help the dual channel memory issue :(

    I have the dual channel problem too, with my new EP45-UD3P rev 1.1 and 2x2G Patriot PC8500 ram. Works fine in slots 1 & 2. I'll start a new thread for my own problems, and I have a case open with Gigabyte, but I'm confused about the current outlook. Has anyone actually fixed this problem with tweaks? Has anyone actually replaced the board and got a good result using the same RAM?

    My issue is still around. I purchased another board and it was the newer rev 1.1 and it did the same exact thing.

    I was trying some new settings tonight and I actually got my system (EP45-UD3P) to post with 4 x 2GB sticks! It's almost through pass 2 on memtest86+ with no errors. Here's what I did:

    My starting point was, everything in M.I.T. was basically the optimized defaults, except this PC-8500 ram I have was marked 5-5-5-15, 2.1V so I had changed the DRAM voltage to 2.1V from 1.8V Auto. Also, I had the Performance Enhancement set to Standard.

    I made all the following tweaks with one stick in slot one, then added a second stick to slot 3 to test. Unless I indicate otherwise I left each change in place.

    1. I set the MCH Core Voltage to 1.300V from 1.100V. Fail.
    2. I changed X.M.P. to Disabled from Auto. This changed the timings from 5-5-5-15 to 5-7-7-16. My notes indicate I might have forgotten to test this change with two sticks.
    3. I changed the SPD Multiplier to 2.00B from Auto. This changed my ram speed to 667, but the system booted with dual channel.
    4. I raised the SPD Multiplier to 2.40B from 2.00B. This changed my ram speed to 800, and dual channel still worked.
    5. I added sticks to slots 2 & 4 to fill the board and dual channel still works.

    So, some combination of increased MCH, relaxed timing, and slower ram speed stabilized the board. I'm annoyed that I paid for 1066 but I get 800, but at least it's a start. It looks like I'll be able to use the OS based tweakers from here on.

    Can anyone suggest next steps? I was thinking of setting the RAM voltage to 2.2 and trying to set the multiplier back to 3.2 and get the proper speed.

    Have you guys tried the new Beta BIOSes?
    JZ Board

    Also, I don't see why you guys don't email some tech journalists or at least the GB tech support guy who is supposed to be here (but isn't). See the sticky thread for his email address.

    GB needs to be made aware of this issue and some pressure applied, as telling the tech support scrubs obvioulsy doesn't work since the issue has been around for a while...
