    Default GA-EP45-ud3p need help with an overclock

    Hi I have an E8500 (E0 Stepping) on a GA-EP45-UD3P (BIOS F8) with Crucial Ballistix 2x2G... With a monster Zerotherm 120mm cooler.

    I'm getting stuck on overclocking the cpu and am in need of some help.. I have the memory stable @ 500

    with these settings

    So I took the stock 3.125Ghz CPU with stock cpu voltages to 3.75Ghz without issue.... Yes I am ecstatic!!
    But I got the speed bug... and I need to know what this baby can do on good air-cooling..

    Here is the problem.. I keep incrementing my Vcore by one step.. and I can get windows to boot.. but then it crashes or prime95 gives a rounding error. Even after tons of reading I still don't get how to bump Vcore, Vtt, CPUpll, and CPUref. I went all the way from Vcore =1.250 to 1.320 in the BIOS.. and it's not happy.

    My Core temps are @ 55 degrees C... which seems odd.. because they were higher @ stock speed. All while under prime95 testing.. maybe the thermal past had to setup...

    Can someone help a Noob?

    Which Crucial Do you have, 2.0V or 2.2V rated sticks? I ask because if it is the 2.0V rated ones I have posted Several speeds in my review, maybe that could help you as well? See my signature for review link

    What are you trying to get to anyway? I need to know before I advise

    I do advise you leave all Ref voltages set to Auto until you know more about them. Setting them to values you see is not advised either. Set Auto for sure if you do not have knowledge of how to mess with them, and even once you do know more you need to be a little more stable before you even think about them

    I have the dual sided 2.0V ones.. they are supposed to be the better ones for over clocking, from what I read.

    I am shooting for 4.25Ghz .. but anything 4Ghz and up works. I would really like to be able to say I have a 1Ghz+ overclock.. but I am not willing to fry it to get there.


    Thanks

    -Dave

    Also the GA-EP45-UD3P is a rev 1.1 with bios F8. I popped off the NB cover and mosfet heat sink covers.. I have a fan pointed at them. I also used AntecSilver on the NB.

    WHY Did you remove the heatsink covers? I hope you just mean the blue plates, if so that is ok.

    Ya just the blue plates you recommended removing in one of your guides. I also replaced the thermal pad on the NB with a good thermal paste. I read your review of the memory in your sig. That's how I got to a stable 500fsb! Awesome reviews and guides btw. Now I have to read them a fourth time to see how I could have missed the cpu stuff.. must have been in the pictures.. argh! :)

    I see you never seem to recommend changing..

    PCI Express Clock Drive.................: [900mV] (default)
    CPU Clock Skew (ps)....................: [0ps] (default)
    MCH Clock Skew (ps)...................: [0ps] (default)

    Any cases were you would recommend it?


    Also for the Vcore and Vtt.. is the general rule to set Vtt to ~ 0.05 - 0.1 below Vcore?

    And the CPUpll... should I make it some relationship of Vcore? Man if someone could create a program that would say try this.. does it work? no then try this next... yes.. then back this off this amount.. did that work.. etc.. etc..

    This seems more like a art form! You are an artist Lsdmeasap!

    I lost stability @ 500 FSB (2.0D, and 7x multiplier) when I lowered the MCH Core below 1.26 .

    This make no sense to me... at my stock voltages for the CPU I can get 3.75Ghz and I have temps of 53...
    but not 4.0Ghz with added voltage.. I must be doing something boneheaded...


    The failure I get is a prime 95 rounding error on a random core.

    Advice???

    Thanks
