    Unhappy Overclocking Help

    I am trying to OC my rig but I can only get to 343 any thing past that and it wont boot. I can change the voltage and all but it wont let me go higher. I have read that this processor can go to at least 500. any help will be greatly appreciated!!!!!!!

    Default Re: Overclocking Help

    Your motherboard will probably only overclock to about 420MHz maximum FSB (aka CPU Host Frequency).
    It sounds like your motherboard's revision number is 2.1.
    It looks like F2 is the only bios version for the rev: 2.1 motherboard.
    The EP45-xxxx motherboards could sometimes go up to 500MHz or higher.

    Go to http://forums.tweaktown.com/gigabyte...tml#post312016, post #3 and copy the bios template into Notepad or any plain text editor.
    Press CTRL + F1 at the main bios screen before you go to the M.I.T. section.
    Ignore any bios settings in the bios template.

    Fill in your current bios settings in the template with the displayed values in the brackets.
    If the bios setting says AUTO, put AUTO in the brackets for that setting.
    If a setting does not appear in your bios, type N/A to the right of the brackets.
    Save your completed template and paste a copy of the template in your next post.
    Once you've posted your bios settings, I'll provide a link for some optimal bios settings for a stock setup and then we will see how much higher you can overclock.

    Include a link to the memory's specifications at the manufacturer's web site.

    A quick web search shows that your power supply is a $28 (list price) unit that sells for $17.98 with a one year warranty.
    A-Power AGS550 550 Watt ATX Power Supply with Dual +12V Rail | $17.98
    This is an old psu design that has no place in any system, let alone a system with an E8400 cpu.
    Most of these POS gutless wonders can fry your system when they fail and some can't deliver even half of their "rated power".
    Most el cheapo power supplies provide dirty electrical power that exceeds the allowable limits for voltage regulation and ripple (aka electrical noise).

    If you're not willing to spend at least $50 or more for a 500+ watt quality psu, you're putting your system at risk!!

    With onboard video only, a good quality 450 watt power supply will meet your current needs.
    Check out psu reviews for decent power supplies that are highly rated by JonnyGuru, HardOCP, HardwareSecrets, PCPER, or TechPowerUp. Most other psu review review sites are a bad joke.

    Check out JonnyGURU - Death of a Gutless Wonder IV: Aces Low to see an example of a very poor psu. Recommended power supplies from JonnyGuru have a final score of 9.0 or higher.

    The first thing we need to do is ensure that your system is stable with stock settings.
    Page 21 in the mobo user manual explains how you can save up to 8 different bios profiles.
    Save your current settings if you want to and give each profile name a meaningful name.

    Every time you go into the bios, first press CTRL + F1 at the same time to unhide some hidden settings.

    Go into the bios and Load Optimized Default settings once.
    You will need to re-enter some bios settings that you were previously using.

    Use the settings below that I've set for the starting point.
    If you have any problems booting or running stress testing programs, provide a detailed description of the problem.
    Saying that your system froze doesn't tell us anything useful.

    Boot into windows and follow step 4 in http://forums.tweaktown.com/gigabyte...tml#post295784, post #5. You will need to post a tightly cropped screen-shot of these programs. Don't post a screen-shot of your complete desktop or we won't be able to read the results. Don't install or run EasyTune6 on your system as it won't provide the information we need to see with EP45 overclocked systems.

    GA-EP45-UD3P - Won't boot with 450FSB
    is a very long E8400 overclocking thread.
    Dan did an excellent job posting useful screen-shots and information about his results. Take a look at some of his thread to see the type of information and detail we will need.

    Prime95 will be the main stress test that you will need to run many different times.
    If you have trouble booting, you will need to run a bootable floppy, usb, or CD with Memtest86+.
    http://www.mersenne.org/freesoft.htm
    Memtest86+ - Advanced Memory Diagnostic Tool <-- downloads are in the middle of the page

    http://forums.tweaktown.com/gigabyte...ity-tools.html has links to many excellent programs.

    Any questions?

    Motherboard Model: GA G41MT-S2PT Rev#: 2.1 Bios Version: 2?
