hey everyone im new here. been reading up on overclocking for a few days now and just looking for some help if you wouldnt mind.
i was going to buy a new computer but i decided to squeeze some more life out of this thing but i want more performance.

i have

Gigabyte ep45-ud3p mother board
2 x 2g kinston ddr2 1066mhz
2 x 2g kingston ddr2 800mhz

i would like to at least get to 4ghz + more if i can?
i know how to turn the clock up in bios but im just not to sure about the amount of voltage or if i should leave it in auto?

also with my ram i have 2 sticks of 1066 and 2 sticks of 800 can these be overclocked?

anyway if some one could help me out with some of the other setting i should change or voltages it would be really helpfull. i think i have enough cooling for it.

set your cpu vcore to 1.25v to start. for 4.0. you may have to go up. my x5470 will do 4.0 at that voltage but i've seen others have to go higher.
cpu term 1.3
fsb 1.4 don't go higher. after you find your stable max overclock you can try 1.3 but with 4 sticks of memory you'll prolly need 1.4v
set all other voltages to normal. do not leave them in auto as the board will set them higher than they need to be.

one thing you may have trouble with is if the timings on your 2 different types of ram is different your stuck that way. your best off to manually set your ram timings for overclocking your cpu and if there different that might not work out

make sure to adjust your memory latch to keep your ram speed as close to stock speed without going over. at 4.0 your fsb will be 400 so youll be at exactly 800. once you go over 400fsb you'll have to back it down under stock until you find your max overclock then you can try setting it to the lowest setting over stock and bump up your ram voltage and test for stability again. if your kingston ram is value ram i wouldnt try going over stock speed at all since you may not be able to manually set timings.
