    Default Motherboard voltage self-test before post?

    GA-X58A UD3R rev 2.0
    HX3X12G1600C9

    I finally retrieved my other problematic desktop and tested the ram kit. The kit is fine. This means that I have a system now that does not have a hardware issue. And in fact, I am able to set BIOS to settings I could not before on either system.

    My new system does not have a cold boot issue or buzz an error beep code. It recognizes full memory and consistently passes Memtest. But the system does not boot properly, either.

    When I press the power button, the motherboard does not immediately display the Gigabyte logo or post. Instead, it seems to fail the voltage self-tests several times before posting/booting properly.

    I don't know exactly what this process is called, but my feeling is that something is not completely stable. My intuition is that I may be able to make the system boot properly if I can find the right secondary memory timings. Raising voltages do not seem to affect the process.

    Do you have any suggestions on how to manually set memory timings? Is there specific timings I should experiment with first, like trc and trfc? Or should I just raise the value of all of them by a lot and lower them one by one to see what happens.

    Here's the relevant BIOS settings. I left the rest on AUTO.

    BIOS frequencies:
    CPU...19
    QPI...36
    Uncore...18 (2x, 2x+1, 2x+2 each behave the same)
    Memory...8
    BCLK...200

    Memory timings:
    9-9-9-24 1600

    Voltages:
    llc...AUTO
    CPU VCore...1.3
    QPI/VTT...1.36
    CPU PLL...1.8
    VDimm...1.6

    Interesting. I cannot manually set twr to max if I manually set, I think it is, twtp.

    Are you using latest bios? I don't really mess with advanced memory timings so I can't suggest anything,it should run fine with advanced timings on auto though,and its normal sometimes for the mb to double boot before it boots up

    I tried testing certain settings one at a time. But these did not affect anything.

    tRC...9+24=33

    tWL...9-1=8

    CMD...2

    tRFC...(64, 90, 110)

    I didn't understand tWTR, tWR, and tWTP.

    But I'm starting to think that I am going to have to live with this boot behavior.

    @Wazza300

    Would you happen to know what is going on when the system does this? Doesn't it seem to you that a double boot--it has happened only once--is a sign of some sort of instability?

    It boots to check/varify bios settings then reboots into Windows,could be bios issue as I remember my mb doing it on very early bios versions but now it doesn't do it all from a few bios versions ago

    Well, since the system eventually boots up fine, I guess what I need is a program that can tell me what kind of settings BIOS configures for AUTO so that I can try setting these manually to see if any will solve the temporary post faults.

    Is there a program you would recommend that could reveal the voltage, frequency, and memory timings in the Windows environment? I will assume for now that the AUTO settings that posts is the settings I should try.
