    Default Best stable settings

    What would be the best stable settings for my p.c. I,am trying to over-clock to 4 gigs here is my system spcs.

    GIGABYTE GA-EP45-DS3R ,Intel Core 2 Duo E8500 ,
    G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500)

    Sorry about that!!! I musta misread your CPU, all is good for the above ram settings, thanks for the link.

    Here is corrected settings per 4Ghz for your CPU >>>

    MB Intelligent Tweaker(M.I.T.)
    Robust Graphics Booster ...............: Auto or Fast
    CPU Clock Ratio ..........................: 9
    Fine CPU Clock Ratio.....................:.5
    CPU Frequency ...........................: 4.037


    Clock Chip Control
    Standard Clock Control
    CPU Host Clock Control..................: [Enabled]
    CPU Host Frequency (Mhz) ............: 425Mhz
    PCI Express Frequency (Mhz) .........:Set to 100

    C.I.A.2 .................................:[Disabled]


    Advanced Clock Control [Press Enter]
    CPU Clock Drive...........................: <<< 800
    PCI Express Clock Drive.................: <<< 900
    CPU Clock Skew (ps)....................: <<<
    MCH Clock Skew (ps)...................: <<<


    DRAM Performance Control
    Performance Enhance...................: [STANDARD]
    Extreme Memory Profile (X.M.P.).....: Disabled
    (G)MCH Frequency Latch...............: [Auto]
    System Memory Multiplier ..............: 2.40B
    Memory Frequency (Mhz) ..............: 1020Mhz
    DRAM Timing Selectable ................: [Manual]


    Or you can use 9x450 for the CPU with 2.00D as the ram multi for 900 MHz ram and maybe use 544-12/15 or 554-12/15.

    Hard to get at exact 1066 with 4Ghz as you will not likely get 2.50A Stable, but you can try it
