Thread: Gigabyte GA-EP45-DQ6 refuses to post




  1. #1

    Default Gigabyte GA-EP45-DQ6 refuses to post

    I've owned this board for like a year now and I'm having this annoying issue.

    About half a year ago, my board would refuse to post and each time I would have to remove the battery to fully clear the CMOS and it will post again. Using the onboard clear CMOS button will not work. This would happen like at least a month but I thought, no big deal.

    Right now its doing it quite frequently and I'm quite annoyed by it. Any ideas whats happening? I've used 2 different BIOSes, same result, I even switched RAM, still the same thing. Is my board dying or what?

    If removing the BIOS abttery helps then it's probably the board. You could spend hours changing other componentes to be absolutely sure, but it's very likely that the problem is the board itself.

    The refusal to post could be your settings, if you think this could be an issue grab a template from my signature and give us your settings and we can check.

    As for the CMOS Clearing issue, that could be the board or CMOS Button failing, how long do you hold it down? If you need RMA info let me know

    Here are my current settings:



    Sorry I will try to get a better version with that template you provided me, but this will do for now.

    Also, Easytune states my CPU PLL is at 1.7 when its really at 1.5.

    I've tried raising the volts on my DRAM to 2.0-2.2, the same thing happens. Could it be my RAM that could be at fault I wonder? I'm using a Corsair DDR2 4GB PC-6400/800 (2x XMS2 2GB) TWIN2X4096-6400C5DHX Ram

    PLL, when it is really at 1.5? What do you mean by that? it is set to 1.76 now and that is a problem, please set to 1.5-1.58 for now.

    I assume you are using Auto/looking at the left side of the BIOS? Those settings are NOT What auto uses for anything and can be safely ignored

    I can see you have way to much MCH Set for 4GB of ram and your FSB.

    I have seen a few issues with that ram, but not for a while so I can't track them down for you. I tried to get them to send me a set or few for testing but they blew me off so I can't really say for sure either way if it is a compatibility issue or not

    Please do give me your FULL settings in a template as you may have other issues I can't see in easytune, then I will advise back on some things to try

    Please use a template to give us your settings, it is much easier for both of us that way.

    I am looking at your images now though and will advise back

    Set PCIE Freq 100

    Set Performance Enhance to Standard

    XMP Disabled

    Set your memory multiplier to 2.00D for 900Mhz ram instead of 1070Mhz

    Then change to manual for the ram and set 555-15

    Then set Driving strength per channel to 1066

    Set Static tRead per channel to 9

    Set your ram voltage to 1.85-1.9v for now to be sure this is not an issue

    Lower MCH Core to 1.20-1.24

    Vtt, you may need more or less, try 1.32-1.34 if no luck try less (DO this last I suppose:)

    Thanks, right now using those settings you provided me, it now boots properly, though when I turn on my machine it will turn off for a second and therefore turning itself back on and will boot normal with my overclocked settings. Is that meant to be normal with these settings or what?

    Anyway, thanks for your help, I will post something again if these settings will fail, must give it time because my motherboard refuses to post randomly (No specific time frame)

    Sometimes yes, at high FSB this can be normal. You may need to adjust things still a little though to gain stability and this could go away.

    Please do stress tests things to be sure, that way if you do have issues and you know your settings are stable we will have to look into other things. Please run 5-10 full passes, or overnight if you can, of Memtest86+ and then 12 hours or so of Orthos or Prime95 Blend
