Intel Q9450 + XFX 790i Ultra = Help me Overclock this bad boy

post #1 of 2
Thread Starter 
Hey Everyone,
I have the new intel q9450 (cooled by an ultra 120 extreme), xfx 790i ultra motherboard, 2gb ocz 2000mhz ddr3 , (read all of my specs on my profile)
This is my first build, and I want to overclock to 3.6ghz. (or higher!)
I want it to be stable, and I want to keep my ultra 120 extreme cooler.
The only problem is, i know NOTHING about overclocking.
Can someone help me out?
I don't need to be baby fed, i just need instructions.

Thanks,
Danny

^Lot's of info with regards to OCing 45nm quads...

The gist of it,

45nm quads don't need piles of core voltage to achieve high clocks, the downside is that OCing them much beyond ~425FSB requires some obscene NB, VTT(sometimes called fsb termination voltage), FSB and PLL voltages.

Supposedly though, 790i and G35 based mobos have seen more consistent 450+FSB results.

FSB = 1800 (450x8)
Memory = 1800 sync mode timings (8-7-7-24 2t)

voltages
cpu - 1.375
fsb = 1.35
memory = 2.00v
spp (NB) - 1.45
mcp (sp) - 1.550

also disable all the extra cpu settings like speedstep and c1e erc....

disable all of the spread spectrums as well and you should have a rock solid 3.6ghz cpu.....let me know how it goes.
