    Default New Rig Setup...

    I just went from a dual core HP laptop to my new rig. I need some advice on settings, but ultimately it's the fastest most sound system I made to date.

    Its components include:

    Gigabyte EP45-UD3P Bios F6+Thermalright Ultra 120mm & IC 7 Diamond & Thermaltake SilentCat 120mm
    Intel Q9950 C1 Stepping
    2 Western Digital 250 gig 16mb Cache SATA II Drives in Raid-0 Array
    8 Gigs OCZ PC-8500 Platinum (5-5-5-15)
    PC POwer & Cooling Silent 610 watt SLI Certified 80 Plus Power Supply
    CoolerMaster "CM-690" (Nvidia Edition)

    I have the voltages on AUTO in the bios except the CPU voltage which I manually adjusted to 1.41250 with LLC DISABLED, but under ET6 it shows 1.36-1.376 volts.

    I included screenshots of ET6 settings and will say the system passed OCCT and runs all my programs stable @ 500FSB and 4ghz yet I have had the system to 4.25ghz @500FSB with the 8.5 multiplier and higher CPU volts (I believe over 1.4 volts) and just couldn't get it to pass OCCT.

    Attachment 758


    I t would tun for about 10 minutes or so making believe it may be me not understanding all the bios settings available. I also when running the system at that speed had all voltages on AUTO except CPU voltage.

    I am wondering if anyone has any ideas on settings to make her stable @ the 4.25ghz. Her temps @ 4ghz topped on OCCT is only 60c and when 4.25ghz 71c. I appreciate all suggestions, but either way this thing is MUCH better than any laptop.

    OUCH!!!

    Please find and set your own Vtt (Termination) and PLL Voltages, Auto always sets them WAY to high when overclocking as you can see, or should have I guess. But hey we dont all know about these things I guess. Vtt over 1.45 has been known to KILL a 45NM cpu very quickly

    So please find and set a stable voltage of your own for those!

    PLL you can likely use 1.5-1.59
    Vtt you can likely use 1.25-1.36

    Please see the link in my sig for how to set your MCH ref, you may need to adjust it to .68-.72 % or so, that may be what is stopping you from stability. But you will HAVE to find your stable Vtt first for sure.

    I tried your settings and the system freezes completely at around a minute of testing with OCCT. No blue screens, or data corruption.

    I definetly don't want to harm any of the components. I was wondering if another setting could be adjusted to produce stability.

    Maybe I should just start with CPU core and increase or North bridge?

    I have gotten the PLL setting to 1.65v passing OCCT, but the VTT had to be 1.6v.

    I read your sig, but am trying to understand it. I hate to be impossible, but I'm a little slow when you get to percentages.

    I think what your saying is I need to adjust for ET6's auto adjustment.

    So when using your adjusted recommended settings of VTT 1.36v what's the MCH Ref voltage?

    I don't know if I'm alone on this, but I believe each voltage your suggesting works to drive another. I would imagine when topping out on one setting due to safety limits it's time to adjust another one.

    I really appreciate your continued support.
