  • Help overclocking x5460 / GA-EP43-UD3L past 3.99ghz

    Hello, I'm new to these forums.

    I'm trying to overclock my Xeon x5460 past 3.99ghz. I've ran IBT for 10 loops at high passed successfully as the screenshot shows. I'm using a board I recently required from a friend, the GA-EP43-UD3L. Raising the FSB any higher causes the system to fail to post. I've tried to change many system but unfortunately my knowledge fails me, so here is my settings:

    Robust Graphics Booster: Turbo
    Clock Ratio: 9.5
    Host Frequency: 420
    CPU Frequency: 3.99
    PCIe Frequency: 101
    Performance Enhance: Turbo
    (G)MCH Frequency Latch: 400mhz
    SPD: 2.00D
    Memory Frequency: 840
    vCore: 1.325
    CPU Termination: 1.2
    CPU Reference: 0.805
    MCH Core: 1.1
    ICH 1/0: 1.55
    DRAM Voltage: 2.0
    CPU and PCIe Drive: 800mv
    CPU and MCH Clock Skew: 0ps

    Suggestions? Also tried putting the SPD at 2.6D, but would fail IBT.

    (I really didn't want to post this, seeing as many others have similar threads, but it was difficult for me to parse through those threads, especially seeing that none had the same chipset I had. Even with the knowledge I did gain from those threads, I couldn't get it past 3.9. I know this thing can go farther because on my old G31 board I was able to at least post at 4.2)

        P43 motherboards might not be able to use CPU Host Frequency higher than 415 - 425MHz.

        Lower the cpu multiplier to 8.5 or 9.0 and see if your system works with CPU Host Frequency = 425MHz.

        I'm surprised that a G31 motherboard could run at 4.20GHz.

        Performance Enhance = Turbo might be part of the problem but it might be OK with 800MHz memory speeds.
