Quetsion about nVidia 680i mobo and Corsair Dominator RAM

Hi All,

I bought a EVGA 122-CK-NF68-AR NF680I 775 and TWIN2X2048-8500C5D RAM. During bootup, it says it is running at 800 MHZ, but the RAM should be 1067 MHZ.

I am assuming I need to OC the board to get out of the default settings. Has anyone worked with these two pieces and got it to work?

Thank you

  1. Hi!
    BTW have you tired to Clear CMOS?? My memory clock is 1050MHz :( 5:5:5:15 2T.

    Like you I have the same mobo, memory and (?) E6600 CPU.

    In addition, I have 2 XFX 8800GTX ( 1 is not installed due to inadequate :( 600 watt PSU), and Tuniq 120 HSF.

    I used the following as my guide to OC this CPU.IGN: CORE @ DUO OVERCLOCKING

    There is another Overclocking Guide by Nvidia in PDF format. Try Google.

    OK now the results.

    So far my max OC is 3.150GHZ FSB 1400 (350 x 4). This is whether I increase the voltages or leave it at AUTO. So I left them on AUTO!

    The program ORTHOS (Blend - Stress CPU and RAM) displays an error within seconds if my FSB > 1400. At 1400 I ran ORTHOS over nite w/o an ERROR.

    The guide's rec voltages for this CPU/MOBO are:

    CPU CORE 1.45v
    CPU FSB 1.5v
    nForce SPP 1.50v

    The max for memory is 2.2v ( see Corsairmemory.com)

    IF you or anyone have any recommendations I would appreciate it.


    I have on order an ANTEC|P180B BLACK CASE and Coolermaster RS-850-EMBA Real Power 850 Pro 850w Power PSU to fit and run the second 8800GTX card
