How far to Overclock an E6420 CPU?

I am overclocking my E6420 (on my ASUS P5B Deluxe board) and would be interested to know what people have acheived with overclocking this CPU (or the E6400, which I assume would reach similar results).

I've got to 3.2GHz without trouble, but would be interested to know how far others have got to know how far to try to push it.

Many thanks!

You push it until it takes more voltage than you feel comfortable running through it.

3.2 is pretty good.

It's going to take a TON more voltage once you start hitting 3.3-3.5 GHz.

3.2 Ghz is great for E6400

Hi Guys ...............

i have E6420 cpu but in the BIOS i can't find the option to increase the bus speed ??? plz help
and it's written on the cpu package max voltage 1.35V i'm wondering in i increase the voltage to OC my cpu what will happen????

Here's my full pc spec :

INTEL DG965RY M.B WITH 1066 MHz FSB
INTEL C2D E6420 2.13 GHz 4MB L2 CACHE \ 1066 MHz FSB
KINGSTON 3GB \ 333 MHz
200 WATT PSU

Intel motherboards typically are not good overclockers. Many of the necessary BIOS options are missing.

I don't know why everyone is saying 3.2Ghz is a good place to stop. If you have a multi of x9 then you should be using it. I'm at 2.8Ghz on my E4300 and can hit 3.4Ghz easy but still waiting on my new heat sink from newegg. BTW the 3.4Ghz I have hit and was stable at besides 70c temps is on a cheap 65.00USD gigabyte board.

Just a little tip last night I ran my E4300 at 3.15Ghz and it wouldn't hold temps under Intel's TAT program's cpu stress test; however, I reset realtemp's log and tried playing a very cpu intensive game ( Empire: total war, and supreme commander) on all max settings. I loaded a seige battle with lots going on during the whole battle. After it was over I quit the game and checked Realtemp's log and my cpu's highest temp was 63c.
