    Default Setting Motherboard Voltage To Normal?

    This is my first attempt OC'ing. I followed the advice from a youtube Gamebeat tutorial that suggested putting the motherboard voltage controls to Manual when doing a mild OC. Colored a few other items in Red that might be questionable. Limited by the 800mhz ram, but will be upgrading this in the future.

    No problems in Prime95 and temperatures below 45˚.

    Im watching some overclock results myself ,but for a quick reply,,stay away from any "normal" settings.Everything on auto is ok at lower overclocks tho obviously you will have to have"CPU host clock control" enabled to overclock.
    Current Systems:

    With the Gigabyte EP45-UD3P it is recommended to leave these settings on "Normal" for a mild OC, setting to "Auto" will overcompensate for the voltages which is not good.

    Maybe I should be putting values into the Voltage settings, then I'm staying away from the Normal & Auto setting all together.

    Mmm recommended..not recommended..who knows...the general sdvice here tho is normal:bad ..auto good.. for moderate overclocks ..at 400 fsb youre already moving beyond mild.. but hey whatever works for you.

    If I'm beyond a mild OC, should I start putting in some lower settings, then check for stability.

    It appears that you didn't load OPTIMIZED settings before you started your overclock.
    This post has suggested basic settings.
    You can save up to 8 bios profiles, see this post for more info.

    Include a link to your memory's specifications for more suggestions.
    There is no benefit to lowering your voltages with your current settings.
    If you are going to overclock higher, some of your voltages will need to be increased.
    Your memory might be stable at speeds up to 1100MHz.
    You can improve your memory's performance by changing:
    Static tRead Value = 7
    tRFC = 52 <--- lower is better, 48 might be stable.
    Please describe which stability tests you have run and for how long.

    Thanks for the great info profJim, I will start with the Optimized settings and also follow the suggested basic settings for a starting point.

    Memory Specs:
    4096 Megabytes of DDR2 memory
    Two matched CM2X2048-6400C5 G modules
    100% tested at 800MHz in high performance DDR2 motherboards
    Each module pair is tested together at 800MHz
    Packaged together immediately following system test
    Tested at JEDEC standard latency settings (5-5-5-18) at 1.9V
    SPD programmed at:
    JEDEC standard 5-5-5-18 values at 800MHz

    8300 is 7.5 max multiplier yes?
    Well i have a feeling/theory/ generally see quad core 775 running 490-510 fsb on air cooling maximum.
    My own personal experience is that you can test and run everything on auto except for the 3 main voltages cpu,memory and memory control hub up to 450 fsb.After that cpu termination vtt and pll (fsb)voltage tend to go very high on auto.Im not saying the pc wont run ok.. just that the voltages go high.
    Get programs such as memset,cpu-z(cpuid) hardware monitor etc to see what sensor voltages are being applied or even ET6 .
    Dont go too far and go in stages as usual.. to see what component is failing at the higher speed etc etc.
    Once you get something running at around 450 fsb u could post bios settings for suggestions or even carry on if you dont feel you need them.
    Seeing how fast your memory will run using a memory multiplier while still at a lowish fsb frequency I found was a good way of getting a feel for the board and your components.
    check other sources too.

    Things like: I just checked newegg user comments on my memory today and noticed 2 other people had found 2.2v was needed for 1000 mhz mem speed.. something Id found awhile ago but all info helps.

    I've taken cpu termination vtt and pll (fsb)voltage off AUTO and set them to the value displayed in my BIOS.

    Should I be setting ICH I/O & ICH Core to the values displayed in my BIOS or leave these on AUTO.

    Thanks for the advice, I'm now at (450x7.5) 3.375GHz. I will post BIOS settings once I get near the max for the Q8300.

    3.45GHz is the highest someone has got the Q8300 up to, so I'm getting near this now.

    Just so you know, when pushing for overclocks you will need to set your own (Not stock) Vtt and PLL

    ICH can be left in auto, but if you have many drives or larger or multiple GFX Cards a small bump wont hurt anything
