    HI guys,

    So I bought some memory a good while ago when I got my new computer, and as I had the AMD 3870k went for 1866mhz DDR3.

    When I boot up however the BIOS posts the memory as running at 1333mhz. When I go into the bios to try and change this, it will often either (a) complain about the overclock and that the settings arent right, or (b) just revert back to 1333mhz.

    I was wondering why this is the case and how I might put it up to 1866mhz. I have run memtest on the stick and it was absolutely fine, 0 errors.

    The memory is Corsair vengeance 1866mhz DDR3, Gigabyute ga-a75n-usb3 mITX motherboard with a standard AMD A8-3870k-BE CPU.

    Thank you!
    Bogo

    The board can run the memory at 1866 so it shouldn't be a problem.

    Have you updated the bios to the latest version? That would be my first port of call.

    1333Mhz is that rams SPD speed.
    Are you running it in XMP? which is what corsairs website states as the tested speed 1866hz.

    Check the voltage in bios matches the manufacturers recommendation for the ram. It might be worthwhile nudging it up slightly too.

    Remember to also set the correct voltage and timings.

    This was the problem, thanks! I checked the corsair website, and then what my motherboard auto set when I went to 1866mhz and they were VERY different, so I did it all manually.

    All at 1866mhz! :)

    Now, for the A8-3870k-BE to 3.6GHz :D
