    Default Overclocking My GA-EP35-DS3L

    so im pretty much set to go, aftermarket coolers on GPU and CPU, gpu idle at 37 and cpu at 40. ive been tempted to do this myself but posses no experience whatsoever, read a couple of guides but felt really general and not expecific, my first custom buld and as you can imagine i wanna avoid wrecking it because of my stupidity, anyways how far can i really push this right? all help ir greatly appreciated


    Intel Core 2 Duo E8400 Wolfdale 3.0GHz

    CORSAIR XMS2 2 x 2GB 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)

    Radeon HD 4850 512MB

    any other info necessary ill be more than glad to provide. thank you!

    You can do 4Ghz easy with that setup. What CPU Cooler did you install?

    You will be fine, just always keep a eye on your core temps.

    Here is some optimal settings for you to try out. Keep in mind CPU Voltage will all be up to your chip, so you will need to set it high at first so you can boot. Then lower until it wont boot and then go back up a notch or two. Also, do check with CPU-z what your actual voltage is from what you set in the BIOS to what you get in windows, and keep that in mind when adjusting >>>

    Robust Graphics Booster___________ [Fast]
    CPU Clock Ratio ____________ [9] 
    Fine Clock Ratio ____________[0.0]
    CPU Host Clock Control_ [Enabled]
    CPU Host Frequency (MHz)__________ [450] 
    PCI Express Frequency (Mhz)_______ [100]
    C.I.A. 2__________________________ [Disabled]
    System Memory Multiplier (SPD)____ [2.00] = 900Mhz ram speed
    DRAM Timing Selectable_______ SPD __ [Manual]
    Performance Enhance = [Standard]
    CAS Latency Time________________ 4/5
    Dram RAS# to CAS# Delay_________ 4/5
    Dram RAS# Precharge Delay_______4/5
    Precharge Delay (tRAS)__________ 12/15/18
    ^^ Set to what you see on your ram sticker ^^^
    Set to all highest below, and then lower later one by one testing with Memtest86+ as you go >>>
    ACT to ACT Delay (tRRD)_________ 3-4
    Rank Write to READ Delay________ 3-5
    Write to Precharge Delay_________ 4-6
    Refresh to ACT Delay______________ 46-50 (52-62)
    Read to Precharge Delay__________ 2 (3-6)
    Static tRead Value_______________7-10
    Static tRead Phase Adjust________ [Auto] << Always Leave
    System Voltage Control____ [Manual]
    DDR2 OverVoltage Control__ [+0.300V] = 2.1V (( Check your ram's sticker and set accordingly.  If it is 2.1, after you are all setup and tested to be stable you can try 2.0
    PCI-E OverVoltage Control_ [+0.1V] << For stability
    FSB OverVoltage Control___ [+0.1V] << For stability
    (G)MCH OverVoltage Control [+0.2V- 0.3V] << Needed for 2x2GB 
    CPU Voltage Control_______ [1.325-1.35] << you may need more or less, as stated above
    Limit CPUID Max. to 3.....................: [Disabled]
    No-Execute Memory Protect............: [Enabled]
    CPU Enhanced Halt (C1E)................: [Disabled]
    C2/C2E State Support....................: [Disabled]

    CPU Thermal Monitor 2(TM2) ...........: [Enabled]
    CPU EIST Function.........................: [Disabled]
    Virtualization Technology................: [Disabled] Enabled if you use Vmware/Virtual PC
    Integrated Peripherals
    Legacy USB Storage Detect___________________[Disabled] *Note* Must be enabled to flash from USB
