Intel I5 2500K 3,3 ghz to 4,0 - How?

These are my specs:
CPU: Intel I5 2500K 3,3 Ghz
Graphics: Nvida Geforce 9800 GT
RAM: 8 GB DDR3
MB: Asus P8 P67

I want to overclock it to 4,0, so two questions:
Can I? and if yes then how do I do it safely?
Thanks in advance

I guess you can, it's only 21% of OC, my rig is OCed 37,5%

Increase the speed in 25/50 MHz each time
Try to do it with stock vcore
Memory may be OCed too

4.0Ghz OC can probably be done on stock voltages. Keep in mind, the 2500 overclocks itself underload to 3.8.

Im not positive on your particular Motherbaord, but there are plenty here very familiar with them. Just hang on tight and Im sure someone will be along shortly to help.


But, essentially all you need to is find you CPU multiplier setting, and change it to manual. Then change it to x40. And thats it.
Depending on your particular chip, you may also need to tweak the voltages a bit, then again, you may not.

And as always, you will still need to test it for stability

Thanks so much for your help!

make sure to run a stress test to ensure its stable. Just because you can boot into Windows and get a few apps up and running does not mean its a stable OC.



Also, watch your temps very closely. You never mentioned what cooling you had, and I didnt think to ask. but thats important.

With small OCs, you may be OK with the Intel HS. But thre are also other variables such as ambient temps and how much airflow your case provides. You may need to back it down if it gets to warm, or get a better cooler on the CPU.

Personally, for 24/7 use I would say stay between 65-70C under a Prime or Intel Burn test load.
