    Default New to OC'ing - EP45-UD3R + Q6600, Help Please

    Hello, I have never overclocked a machine before and would like to give it a try with a small overclock to 3.0. Unfortunately all I really know to do is switch the CPU Frequency to 333 and I've changed my DRAM voltage to 2.0. There are so many other voltage options and such that I'm lost, any help with all the correct settings would be much appreciated.

    Here is the ram I'm using. Newegg.com - Crucial Ballistix 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory - Desktop Memory

    And if it matters, this is my PSU. Newegg.com - CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Power Supply - Power Supplies

    Thanks a lot for any help.

    I would use this as a optimal range for your ram and CPU at 3.0, CPU Voltages will of course be up to you to find and set, dont use Auto >>>

    This is Just a template I use to ask people their settings, pay no attention to the numbers in it, replace with yours

    Thanks Lsdmeasap,

    I was able to bring down all the settings to the lowest you recommended. I brought my cpu voltage down to 1.2875 which seemed to be the lowest it would run stable. From everything I've read here the lower the better, is that correct?

    Running the high heat settings in Prime95 everything ran between 51-55 never going above 55. I believe those are acceptable temps??

    Thank you for your help and your time Lsdmeasap.

    Oh also, are there any good in depth resources you know of that can explain in detail most of these settings and what/how they effect the components. I see you talk about straps and things that are beyond me in a lot of your posts and would like to learn what all of that it is. Mostly I would like to learn and understand it all better so I'm able to do this myself in the future. Thank you.

    Sorry for the late reply!

    Ya, lower voltages are better as long as they are stable for you!

    And yeap, those temps look good as well!

    Well, other then the guides I have posted not really. Much of the info is scattered about on the forum for P45 that I know and have posted. I need to get a guide wrote up with some overall coverage of the boards but just have not had time yet. I am reviewing the board I am using now, maybe I will add some in depth knowledge about alot of it to my review. I did plan to add in alot of my findings about various things so I might as well make it a Review/Guide. Just need to find the time to get it done!

    Straps are just the NorthBridge's internal speed and timings.

    The lower strap chosen the better the performance, less stable things may be without higher voltage or loose ram timings. Higher the strap chosen will be Faster Northbridge Speeds with looser internal timings on the NB, and would be more stable and need less voltages to run.

    Normally you want to run using the strap closest to your FSB, but you can use one above if you find the one your FSB is in unstable. You can also use a lower one for better performance if you adjust voltages and ram timings to allow it to be stable.

    tRD (Static tRead Value) and MCH voltage have a large effect on what strap you may use as well. P45 is very picky when it comes to NB/MCH voltages. Sometimes a lower voltage would be needed when you would think it should obviously be more. And often times the opposite is true. As for tRD, depending on actual ram quality and all other settings (Voltages and timings) you may be only able to use lower tRD on lower straps

    Here is the available straps >>>




    And while I have my review notes open, here is some GTL Ref voltage info I am working on for my Guide/Review >>>>

    By Random User:

    For me, All the references in ET6 are wrong or always show the same defaults. Why is this?
    That is ONLY because ET Shows the .xx % of Vtt of what you set in the BIOS. The Default Value of MCH Ref is .63% of Vtt at stock of 1.20V, which is .756 (.76)

    The Ref Settings in the BIOS are .xx % values of/X Vtt so this tends to throw off many users when they set something and then compare to EasyTune. So you need to keep the % amounts in mind when changing these Ref voltages, and it is easiest to do it at stock Vtt and then raise your Vtt back up to where you want to run it. If you Make any deviation from the stock % for MCH Ref of .63% the value will be reflected in ET

    Here is Four Common examples of this, all using MCH Ref, and 1.30 Vtt (Termination). All of these but the last WILL Change what you see for MCH Ref in EasyTune as well. This way I hope you can see how this works, and then maybe better find your way to tuning your Ref voltages

    *** Examples Below using 1.3 Vtt ***

    (MCH Ref .68% AKA .68 in ET)
    For example if you set 1.3 Vtt and .884 MCH Ref, ET would show .68 MCH Ref as .884 would be .68% of Vtt.

    (MCH Ref .70% AKA .70 in ET)
    Another example if you set 1.3 Vtt and .91 MCH Ref, ET would show .70 MCH Ref as .91 would be .70% of Vtt

    (MCH Ref .72% AKA .72 in ET)
    Another example if you set 1.3 Vtt and .936 MCH Ref, ET would show .72 MCH Ref as .936 would be .72% of Vtt

    STOCK MCH Ref VALUES at .63% (To Help show how ET Seems to always show .76 for users)

    First Example shows stock values for Ref used, .63%. That would be MCH Ref manually set but Value unchanged (.76) and then Vtt Raised to 1.3, or manually set to .819 and Vtt Manually set to 1.3..........

    (Stock MCH Ref W/ 1.3 Vtt / .76 in ET)
    If you set 1.3 Vtt and .819 MCH Ref ET would show .76 MCH Ref as .819 would be .63% of Vtt

    This Example shows Stock Vtt and Stock MCH Ref used.........

    (Stock MCH Ref W/1.20 Vtt or .76 in ET)
    If you set 1.2 Vtt and .756 MCH Ref ET would show .76 MCH Ref as .756 would be .63% of Vtt.


    That is just ONE example, and how to manipulate it, of the Many Ref Voltages in the BIOS Vs. what you see in Easytune. Here are all the values affected by other Values in the BIOS and their respective Percentages.

    CPU Termination (Vtt) Automatically changes the following if manually set >>>

    CPU Reference Voltage (.63% of Default Vtt/1.20) .76 ET
    CPU Reference2 Voltage (.67% of Default Vtt/1.20) .80 ET
    MCH Reference Voltage (.63% of Default Vtt/1.20) .76 ET

    DRAM Voltage Automatically changes the following if manually set >>>

    MCH/DRAM Reference Voltage (.50% of Default Dram Voltage)
    DRAM Termination Voltage (.50% of Default Dram Voltage)
    Channel A Reference Voltage (.50% of Default Dram Voltage)
    Channel B Reference Voltage (.50% of Default Dram Voltage)

    If you want a higher or lower than stock % / Value for any of the above settings you will find it easier to set the Dram Voltage or Vtt back to stock (Or above or below to find and be able to choose alternate % Values), then adjust desired setting to the % / Value you wish to use.

    Then once you have selected a % range you want to use for said setting then go back and raise your Vtt or Dram Voltage back to what you choose to use and the corresponding settings will self adjust and still be set to the .xx % amount that you set them to.

    I also have a GA-EP45-UD3R and am new to overclocking. I would also like to OC to just 3GHz with my q6600. Did the settings that Lsdmeasap gave you work?
    What did you end up settling on for settings? I'd be really curious, as I'd like to try it too. (except my ram is this one)
    Thanks,

    Thanks, I will do that.
    I'm not going to get around to trying this for a while, though. I'll post back then.
    Thanks again!
