Simple overclocking on the Core i5 2500k

Hi all. My system is as below:

Case: Coolermaster HAF 912
Additional cooling: Coolermaster Megaflow 200mm fan mounted in the top of the case
PSU: Antec TruePower New 650W
Mobo: Asus p8Z68 v lx
CPU: i5 2500k
RAM: 8gb Corsair vengeance 1600mhz
GPU: Radeon HD 4850, shortly updating to HD 6870
other internals are SSD, HDD and optical drive.

So my question is, with the set up i have above, what is a rough theoretical maximum i could achieve OC'ing the 2500k by just adjusting the multiplier (no voltage adjustments etc) on the stock cooler?

Basically i want to push the CPU as much as i can without having to get into after market cooling and adjusting values in the BIOS which i dont have a full understanding of.

Cheers in advance for any help.

4.1Ghz. Maybe 4.2.

Personal Experience. You'll run into temperature problems before voltage problems so it depends on your case and airflow. Try to stay below 75C or even better 70C.

Ok, thanks for that.

Is temperature really likely to be that much of a problem if im not adjusting any voltages? What are the chances of permanently damaging the CPU?

If im going one step at a time until i reach an unstable clock, then jump back to a previously stable set, this should be fine if im correct?

Mine using the Auto OC picked 4.2Ghz, I can run 4.3 with the same settings though. My Vcore hits 1.36 according to HWMonitor with Bios setting on Auto. Max temp I've seen is 65c on one core during BF3 and IBT

Cliffro, when you say the Auto OC, are you talking about Asus' in built OC'ing facility? Is this the best way to go do you think, turn that on and leave everything to auto?

You really don't have to change anything other than vcore and multiplier even for a 4.7ghz oc. Aftermarket cooling can be had for $25 and get you to that speed. The stock cooler is pretty horrible, during the summer I had to turn off turbo just to stay in safe temp. The auto oc usually overvolts so I would recommend manually ocing. Stock vcore is 1.2-1.25 turbo which won't get you much more than ~4.0ghz but the issue is going to be temps depending on roomtemp with the stock cooler.

If im honest, 4ghz is perfectly acceptable to me and what i was really hoping for. Do you think this is possible just adjusting the multiplier and using the stock cooler?

Just try it and watch your temps.

Edit: Forgot to mention auto oc refers to either having vcore set on auto or the auto oc feature.

I would really recommend never using the stock cooler intel gives you. I have only had bad experiences with them
