    Post Overclocking an Intel Xeon X5470 on a GA-EP45T-Extreme

    Hi All,


    My first post here on the forums, been a forum lurker for a while however I haven't had the need to post until now. Since it is my first post I will briefly introduce myself. I am from Sydney Australia and am currently studying a business/finance degree full time (2nd year). I've recently starting building PC's from scratch and so far I have put together 3 or 4 in total (mainly for family), I've always had an interest in computers and it is always satisfying having your project boot up the first time . Well we know that doesn't always happen the first boot!


    So recently I decided to set myself a challenge of building a budget computer recycling some old parts that were donated. I will include the specifications below, I am using the 771 to 775 conversion mod as it seems to be the most cost effective solution.


    Mobo: GA-EP45T-Extreme
    CPU: Intel Xeon X5470 (3.33ghz - 333Mhz x 10 Multiplier)
    RAM: DDR3 4GB G.Skill PC3-12800 - Part Number F3-17000CL11-4GBXL
    PSU: 650W
    CPU Cooler: CM Hyper212 EVO
    GPU: NVIDIA Geforce 8600GT (This is a temporary GPU as I am considering the possibility of a GTX 970)
    HDD: Toshiba 500GB (SATA 6.0gb/s) 2.5"
    Optical Drive: LG 24x DVD-RW


    I choose the X5470 CPU as it had good reviews with regards to its overclocking capabilities however I've hit a bit of a road block during the overclocking process. The MIT program within the BIOS gives you quite a lot of room to adjust settings however I am a little confused as to which settings are the appropriate ones to change. So far I have been able to adjust the CPU host frequency in order to achieve a Core speed of 3.99 GHz [3.99 x (6-10)] while still maintaining a default CPU VCore of 1.25V. I have stress tested this configuration with IntelBurnTest @ Maximum RAM for 10 rounds with no stability issues.


    I have tried the following CPU VCore figures with no success of breaking the 4GHz mark, the PC will simply not boot when there is a CPU Host Frequency > 399.


    CPU Host Frequency CPU VCore
    403 MHz 1.25V (Failed Boot)
    403 MHz 1.25625V (Failed Boot)
    403 MHz 1.26250V (Failed Boot)
    403 MHz 1.26875V (Failed Boot)
    403 MHz 1.27500V (Failed Boot)
    403 MHz 1.28125V (Failed Boot)
    403 MHz 1.28750V (Failed Boot)
    403 MHz 1.29375V (Failed Boot)
    403 MHz 1.30000V (Failed Boot)
    403 MHz 1.30625V (Failed Boot)
    403 MHz 1.31250V (Failed Boot)
    403 MHz 1.31875V (Failed Boot)
    400 MHz 1.31250V (Failed Boot)
    400 MHz 1.32500V (Failed Boot)


    I even set the CPU VCore to 1.4V and the PC still failed to boot. For further reference I have attached some pics of how my current MIT is set up. Any help or direction would be greatly appreciated.

    Welcome to the forum.

    It just so happens that there is a forum thread that will help you: Socket 771 Mod Xeon X5460 GA-P35-DS3L Overclock

    There are currently 633 posts in the thread but it's not necessary to read every post.

    If you look at the ET6 (EasyTune 6) screen-shots that Luke provided you will quickly see some of the bios tweaks that were needed for a high overclock and a stable system.

    If you'd like, I can move your post to the end of the thread and you can get help in that thread.

    Send me a PM (private message) if you want me to move your post.

    I've provided a lot of assistance in the other thread where there are two forum members with X5470's and we have covered the basics from tweaking to stress testing and a whole lot more.
