    Default XMP problems on X79

    Hello, i have problems setting the XMP Profile on the BIOS..

    It should work, but it doesn't.. I get a black screen (no signal to the screen)..
    If i disable the XMP profile (Optimized BIOS settings's default), it works..

    My RAM's exact model is: PX534G2000ELK, i have a 4x2GB set.. And my system is in my signature..

    Some info:

    First, your memory is not listed in your board's memory compatibility list. While that is not an absolute indication that it will not work in that board, it might be questionable.

    But more likely the problem is related to this, from your board's memory compatibility list:

    Name:  memory temp.PNG

Size:  52.9 KB

    We see the "downgrade to DDR3 1866" with all DDR3 2000 memory. If that is a board or CPU memory controller issue, I don't know.

    You'll find similar memory speed downgrades for other memory speeds in the compatibility list:

    I would be careful with a BIOS update as a fix, which I doubt would help, and the newer BIOS versions are made for Ivy Bridge E processors, rather than you Sandy Bridge E processor.

    Frankly I thing you're stuck at 1866 with that memory.

    LGA2011 strap feature? See post #2:

    I have similar problem ans a BIOS flash sorted it out. In my case all BIOS versions from F1 to F3u work flawlessly then from F3v to F4 not work and F5(+F5 betas) work fine, and F6 to latest F8 beta does not work. This is for x79-UP4 so for your board BIOS versions may differ. But it is definately BIOS issue. I have alerted Gigabyte support for it and awaiting answer. BTW i am using quad channel kit and still have XMP problems so the RAM is not an issue.

    Yes.. As parsec says, i'm sticking at 1866MHz with 1.5v (XMP disabled, optimal bios settings) FOR NOW!! Until i find a solution..

    But, i searched a bit more, and i found this:

    Intel QPI/vtt Voltage dangerously high in XMP profile

    Maybe is that issue, a voltage issue, that wont let my computer boot..

    As for BIOS version, yes.. In previous versions, XMP Profile1 (auto multiplier) was at 1866MHz (that's why my signature says 1866MHz :P)
    Now, is the first time i see that XMP Profile1 is at 2000MHz with auto multiplier.. I'm using 13C, but i don't really know from what version was at 2000MHz..
