Re: GA-EP45-ud3p need help with an overclock

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

Re: GA-EP45-ud3p need help with an overclock

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

Re: GA-EP45-ud3p need help with an overclock

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.

Re: GA-EP45-ud3p need help with an overclock

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

Those are the Crucial I reviewed, and yes they overclock VERY Well!

Re: GA-EP45-ud3p need help with an overclock

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!

Re: GA-EP45-ud3p need help with an overclock

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
