    Default Overclocking Gigabyte EP45-UD3R

    Hi Im new to Gigabyte boards and I am trying to overclock a E8500 on the UD3R board and was hoping someone could help me out this is what I have been trying.

    CPU FSB clock.............................:400Mhz

    Performance Enhance...................: Standard
    Extreme Memory Profile (X.M.P.)………….Disabled
    (G)MCH Frequency Latch...............: Auto
    System Memory Multiplier ..............: 2.66D
    Memory Frequency (Mhz) ..............: DRAM Timing Selectable ................: Manual


    Motherboard Voltage Control
    CPU Vcore….……….........................1.30V
    CPU Termination…..... 1.22V
    CPU PLL…………………....1.5V
    CPU Referen.…………....0.757V

    MCH/ICH
    MCH Core…………….....1.20V
    MCH Reference….…….0.751V
    MCH/DRAM Ref.…......autoV
    ICH I/O……………….....normalV
    ICH Core................normal

    DRAM
    DRAM Voltage ……....2.1V
    DRAM Termination .…autoV
    Channel A Reference………..0.750V [Auto]
    Channel B Reference………..0.750V [Auto]
    Ch.A Address VRef………..0.750V [Auto]
    Ch.B Address VRef………..0.750V [Auto]

    I have tried a few other setting but so far the results are always the same after I save to CMOS it shuts down then restarts shuts down again and resatarts with default settings. Thanks for any help

    System in this build is:
    CPU-E8500
    Mobo-EP45-UD3R BIOS ver. F11
    Ram- Corsair Dominator PC-8500 2x1gb
    GPU-XFX HD 4770
    PSU-Atec TPQ850

    Please use the template from this post for full BIOS settings.
    Also if you provide a screen capture as explain in step 4 in this post, and add your system specs tou your forum signature it will help to advise you.

    Are current settings stable? What kind of cooling you have, CPU/case/other, what are core temps for full load (Prime95/OCCT/IBT)?

    Everything appears stable Ran Prime95 for a couple of hours temps never went above 45c the case is a Antec 300, for CPU cooling I have a Artic Cooling Freezer 7 PRO. If I forgot anything let me know Thanks again for the help

    Best leave Reference values auto unless you tuned them purposly.
    Have you tried Static tRead Value 7? Did you need all that vcore?
    Personnaly I recomend to use XMP.

    To get any further you'll need to use lower memory multiplier, 2.40B usually work up to 450MHz, then a 2.00X multiplier.

    Set Static tRead 9 or 10 for now, CPU PLL 1.57, and try higher FSB, 425 then 445, VTT(CPU Termination) and MCH may need to be increased 1-2 ticks. You may try with LLC(Load Line Callibration) enabled and less vcire, disputed feature so it's up to you. MCH/CPU references may need further tweaking.

    The screen capture may still be helpfull.
    Is it a total of 2GB memory?

    EDIT: Temps are core temps (read with CoreTemp/RealTemp)?

    Thanks for the reply. I tried adjusting the settings as you instructed seems to be a little closer as after I save to CMOS it shuts down then restarts then it get to the POST *beep* (didn't do that before) then it shuts down again and restarts with default settings. I adjusted:

    Enabled XMP
    CPU FSB: 425

    CPU PLL: 1.57
    CPU Term. 1.28
    MCH: 1.28
    Set CPU and MCH Reference to Auto

    Enabled Load Line Calibration

    I am running a total of 2GB of RAM I had another 2 GB (1GB per Stick) but they are being RMA'ed to Corsair. Im not looking to break records with this rig I was really hoping to just get to 3.8 or 4Ghz. Teps are core temps using RealTemp I ran IntelBurn Test at stock and it passed max temp 52c

    Don't forget the multiplier 2.40B, unlikely memory would do 1130 without high voltage, if that doesn;t work you'd have to use the 2.00D or 2.00B.
    Also Static tRead value 9 or 10m you can try lower it later.

    Oh sorry I forgot to include those I did change the Memory multi to 2.40b and adjusted the read value to 9. Do you know what the maximum safe voltages are for the:

    CPU Termination
    CPU PLL
    MCH Core

    Thanks again for the help

    CPU Termination 1.45 vis max by Intel i think, but you shouldn't need more than 1.32-1.36v.
    CPU PLL not above 1.61.
    MCH Core you probably have enough. 1.21v is max by Intel but there are people that are using 1.4v or even more.

    Maybe it's time to tweak MCH Reference or CPU Reference, see the link I posted in post #4. Try 405-410 MHz FSB untill you get errors with Prime95 or IBT, and then tweak them. Often less than 0.76 @ 1.2VTT MCH Reference is needed (0.7-0.74) but might be more too.

    Try also to use 9 CPU ratio to eliminate the need for more vcore.

    OC temps are more interesting. Under 75c for Prime95 is OK, 70-80c for IBT OK too.

    There is also an F12 BIOS that list enhanced memory compatibility might want to try it.

    Man I have tried a variety of things but I cant even get to a windows loading screen with any of the settings I have tried it always restarts and loads the default BIOS settings. Even a increase of 10 on the FSB results in it defaulting to the default settings. Thanks for the help I appreciate it if you have any other ideas Im all ears.

    Thanks
