    Default GA-EP45-UD3R problems with 1066 RAM

    Greetings all,

    I would just like to throw my hat into the ring as yet another person who has had problems with this mobo and trying to find some stable, worthwhile RAM settings. I've used both 4 GB G.Skill 1066 as well as OCZ Reaper 1066 RAM and neither seem to be as stable as one would like. Perhaps those with the power to fix such things (via a BIOS update perhaps???) will read this and many of the other problems people have been having with this board and throw us a bone?

    Thanks for reading!

    Hello Beavbo:

    In the BIOS, have you tried upping the DRAM voltage (bumping it up to 2.0 or 2.1) ... I believe the OCZ is rated at 2.1V. Also see the Advanced Timing Control settings below. You have LSDMeASAP to thank for this information (if it works for you that is):

    Standard Timing Control
    CAS Latency Time .......................5
    tRCD .........................................5
    tRP............................................5
    tRAS..........................................15/18

    Advanced Timing Control
    tRRD...........................................3-4
    tWTR..........................................3-6
    tWR............................................4-8
    tRFC...........................................52-62
    tRTP...........................................3-5
    Command Rate (CMD) ...................2

    Dear CTBlankenship,

    I use the same mainboard with this guy. Can you give the setting for my RAM: Corsair Dominator 4G 8500?

    Thank you very much,
    Matrix

    Yea, I've tried those settings (and probably about 2 dozen other ones as well) I believe the RAM is rated 2.1-2.2V w/out looking at the box.... At the moment due to the G.Skill RAM I have 6/6/6/18 set with my tRFC being set at 72. Anyway, my whole point with the post was just to point out the large quantity of people who seem to be struggling through this particular mobo and its memory problems, since it seems such things could be fixed with a BIOS update. Thanks for all your help though.

    Cheers.

    It is the BIOS settings availble that give users issues, not the BIOS. The BIOS is fine for those who know how to setup the BIOS, just look at world records are being set with this board >>>>

    DDR2 1680.00 so far >>>
    GIGABYTE--Challenge Dual Channel DDR2 1508MHz Record--Record Breakers

    GIGABYTE--Challenge Dual Channel DDR2 1508MHz Record--MAIN PAGE

    Sounds like you do need some help, please link your ram and fill this out with what you are using that fails and I will advise back. Also note what CPU you have >>>>

    Hey, sorry if I came across as being disparaging toward Gigabyte in any way, I'm sure there are many that have been able to do very good things with their products-- I've just been frustrated that there is no quick 'plug-and-play' as far as getting my setup running smoothly.

    I know what you mean, I just wanted to let you know the board is fine. Plug and Play, that is OEM Dell or HP

    I need a link to the ram you will be using before I can advise fully. Aside from you not setting driving strength profile the above looks ok unless possibly your CPU Voltages are not enough?

    If you are running stock you can leave Vtt on Auto as setting it changes many other things. Here is some explanation of those changes, for later >>>

    CPU Termination (Vtt) Automatically changes the following if manually set >>>

    CPU Reference Voltage (.63% of Default Vtt/1.20)
    CPU Reference2 Voltage (.67% of Default Vtt/1.20)
    MCH Reference Voltage (.63% of Default Vtt/1.20)

    DRAM Voltage Automatically changes the following if manually set >>>

    MCH/DRAM Reference Voltage (.50% of Default Dram Voltage)
    DRAM Termination Voltage (.50% of Default Dram Voltage)
    Channel A Reference Voltage (.50% of Default Dram Voltage)
    Channel B Reference Voltage (.50% of Default Dram Voltage)

    If you want a higher or lower than stock % / Value for any of the above settings you will find it easier to set the Dram Voltage or Vtt back to stock (Or above or below to find and be able to choose alternate % Values), then adjust desired setting to the % / Value you wish to use.

    Then once you have selected a % range you want to use for said setting then go back and raise your Vtt or Dram Voltage back to what you choose to use and the corresponding settings will self adjust

    sorry, driving strength profile was set to 800Mhz. The RAM I have been testing with is OCZ Reaper OCZ2RPR10664GK and G.Skill F2-8500CL6D-4GBNQ At the moment only one stick of the OCZ Ram is in there in slot 1 so it will be stable enough to POST

    Default Re: GA-EP45-UD3R problems with 1066 RAM

    You should use 1066 driving strength then. Well you need to decide on which set you want me to advise you about but those settings above should work more then fine for any 2x2 set as they are very loose timings

    So if you keep having issues try less MCH maybe, try 1.05, then 1.20-1.22

    Otherwise please test each of those sticks one by one at Stock 1066 speeds, not 800 to be sure they are not faulty >>

    Thanks, I'll make those changes when I get home and let you know how they're working. I'll be doing all the testing with the OCZ RAM.
