    O/C E8400 on P45-DS 3R Probleme

    I test overclocker my CPU but the PC does not accept it.

    Mother chart: Gigabyte P45-DS 3R
    Processor: E8400 (E0)
    Memories: 2x2Go OCZ PC8000

    Firstly, I do not include/understand why CPU-Z detect them as PC2-6400 and not PC2-8000 and I have a question which is the advantage of taking of the 8000 instead of the 6400 if both function with 400Mhz.

    In the BIOS I made the adjustments according to:

    CPU Host Frequency: 400Mhz
    PCI Express Frequency: 101Mhz
    MCH Frequency Latch: 400Mhz
    SPD: 2.00D
    Memory Frequency: 800 800
    Case: 5-5-5-18

    GDR: 2.0V
    CPU: 1.25V

    I find that odd that the o/c does not hold for 3.6Ghz whereas one can normally mount this processor to 4Ghz

    Thank you with all!

    the frequency indicated in your post initial (800) does not correspond to the frequency of a PC8000. Either your BIOS is regulated in the car, this standard does not recognize (small thing to be considered) and is adjusted with a value of PC6400 per defect or you manually defined the properties the speed of the RAM in a bad value.

    400MHz it is thus PC6400 not mystery, the software identify your memory like 6400. They are not soothsayers.

    In all the cases turns over in your BIOS and re-examines this parameter.

    In my Bios, I have to regulate the timings manually and the voltage of GDR but 400Mhz is the maximum value which I can choose. I made the last update of the BIOS in F10 version.
