    Default Request overclocking advice

    GA-EP45-DS3L.E8500,OCZ700watt PS,2x2gig A-Data,rated by them at cl 555-15 2.1to2.3volts..board uses bios v7.Boots correctly at 3.17.Is overclock possible?

    Yes you can overclock for sure. Have you read any guides at all, or started overclocking any?

    What you should do first is set Performance Enhnace on Standard, set trfc to 52-52 and add some MCH Voltage for 2x2GB.

    If you do need more help, please let me know what you would like to run at and Give me your settings you are using now and I will try to advise you >>>

    This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

    YES i've read ur replys and the stickies,i have only a little experience overclocking,but like the idea.performance in flight sims is greatly improved.bios is now ver8.and am awaiting thermalright 120 and fan.

    Well..... You never said what you want to overclock to or need help with?

    These would be your optimal ranges for what you gave me >>>>

    ^^^ If you want to use 900 Ram speed you can likely run with 544-12/15 above ^^^

    Set all below to the higher values then later lower one at a time testing with memtest86+ as you go >>>

    CPU
    CPU Vcore….………...............1.25000V..........: [1.3-1.3800V] (1.385 may be only about 1.32 or so actual) What you set in the BIOS will be less actual, you can check how much less with CPU-z. You may need more or less, or you may get 3.6 with stock voltage, but do not use Auto. All chips are different so you will have to find this amount on your own. Just set high enough to boot, then later you can lower it until it fails then raise back up a few until you get stable

    runs 4050.07MHZ mem tests good at 4 hrs.orthos ran 2hrs till i stopped it temps 49-50,fs9and x-plane both run flawlessly.added a extreme120 cooler pointed at exhaust fan.idle 38-42 core 0,1.normal load 46-47.any more changes? cpu core at 1.264 at idle

    Looks good to me! Especially since your games run good, all you can do is tighten up your timings as much as you can to gain better performance
