Help OC'ing my CPU?

I've been looking at overclocking mine for a while now and had been looking at OCing my previous CPU for a few years, but if there's two things I'm stupidly bad at it's math and electricity, and the fact that both seem to be important has kinda shied me away from trying it.

Looking for some help, or even someone to walk me through OCing it a bit, nothing insane, but I wouldn't mind going up to about 3.0 from the stock 2.5. I've read over the sticky up top a bit and from googling OCing my specific CPU it seems that 3.0 is very easy to achieve.

I am on a stock cooler, and stuck on it for a while, so I'm definitely not looking to change much. Just a bit of a boost would be nice. Information in my sig is up to date.

right, overclocking to 3.0ghz is a good place to start, because it shouldnt take any adjustments other than changing the fsb

on the asus p5k, overclocking is simple and quick. your cpu's multiplier basically takes the fsb and multiplies it by 7.5, so a base fsb of 333x7.5 equals 2.5ghz, which is your current setting.

to get your processor to 3.0ghz, you will want to change the fsb setting in your bios to 400mhz. try booting like this. if the computer fails to boot, let me know.
 
Where in the bios do I change it?
I looked through a few times and could only find current info for it but couldn't change it. Downloaded the manual for the board and it wasn't much help either.
 
Went to 3.0 without any issues. CPU is about 4* hotter than it was before, enough that I'll leave it at 3.0 til I can upgrade the stock cooler.

If it hits 70, that's a sign that the overclock needs to be taken down to maybe 2.7 or 2.6ghz. If you have any, i'd clean off the current thermal paste and reapply it.
 
The temps have been right around that give or take 1-2*. The CPU is only about 2 months old, I've reapplied the thermal paste once since then. It hasn't overheated or gone over 68* since I've had it. Hopefully that'll remain true since the temps haven't changed.

The stock cpu cooler just isn't that great. It's next on my list to upgrade.
 
With idle temps at ~60* I'd be concerned. When you re applied the paste you thoroughly cleaned off the old stuff first right? I've got my Athlon at 3.6Ghz (Up from 2.8Ghz) and even on the stock cooler with a voltage bump I still idle in the mid to high 30's. Hell my load temps are only slightly higher than your idle. Granted its only a little 65w dual core but still, there seems like there's something weird going on there. OC or not, it shouldn't be that hot.

The stock cooler just sucks. My old Pentium D ran just as hot, but even this CPU under load isnt getting higher than about 65* and the max op temp is 71*. I pretty much only work or play games on this thing so they CPU is never really that stressed out.

I'm not that worried about it, I'll be upgrading the cooler once I've got some money anyway.
