Unsure about overclocking, could use some pointers

[Bluemouse]

Hi all,

I have a new machine that I built, and I'm trying to overclock it but I'm a bit unsure of what to do exactly, what is safe, and how much I can go with my specific hardware.

PSU: 700W Stealthmaster
CPU: i5 2500K
Mobo: MSI G43

Ram: G.SKILL Ripjaws X F3-12800CL9D-4GBXL 4GB 2X2GB DDR3-1600 CL9-9-9-24 Memory

Graphics Card: HIS 2GB Radeon 6950 (I'll unlock the shaders on this separately)

What are the things I need to change in my bios? I'm currently using the stock heatsink, so I don't necessarily want to go too high on the overclocking. What can I do with the multiplier?

Thanks for any help!

Cheers

What can I do with the multiplier?

You can do whatever you want, but for overclocking, you should increase it.

What are the things I need to change in my bios?

You don't "need" to change anything; but if you're overclocking, then you'll have to.

I'd guess you can go up to ≈4.5ghz max, probably less.

Right, what i mean is, what do I change

You can increase the multiplier, I said that already I think.
I'd think you could start off at 40x with vcore < 1.3v without trouble.

Stolen from custom pc magazine

Set Cpu multiplier to x45

Enable extreme load line calibration

Set cpu voltage to 1.39v

Set the cpu pll to 1.9v

Set the vccsa to 1.1v

set the vccio to 1.10625v

Save and restart.

This will give you 4.5 ghz, which is a safe everyday level according to the article.

Be sure your cooling is up to scratch, Run a benchmark and keep an eye on temps.

Hope this helps.
