1) restart your pc and enter the bios.. then go to your specific tweaking option which in the case of the asrock P43DE should be the "oc tweaker"( http://i49.tinypic.com/mw5liu.jpg )
2) now as i mentioned you dont need to adjust any voltages.. on this occasion all we shall do is adjust the "cpu frequency " ... this at stock should be 200mhz.....
3)for saftey reasons we shall start light... increase the cpu frequency to 233mhz...... then save and exit the bios.... this will give you a increase of just over 2.9ghz...... this should be fine and should show no instability ... however use the program " prime95" ( http://files.extremeoverclocking.com/fil ) and run this for around 20 minutes just to be sure ........
also you may also have cpu-z allready on your desktop aswell as speedfan... these two programs are essential when overclocking ...... cpu-z to monitor the overclock and speedfan to keep check on your cpu tempeture ... if you havent got these programs you can download them from
a) cpu-z ( http://www.cpuid.com/softwares/cpu-z.htm )
b) speedfan ( http://www.almico.com/sfdownload.php )
so with that out of the way on to step 4
4) so with your first overclock out of the way back to the bios and into the oc tweaker.... and this time you want to increase the "cpu frequency" from 233mhz to 266mhz ..... this will increase your speed to a healthy 3.34ghz ....... and again save these changes on the main bios screen and run prime 95 in windows to check for stability ....... however since the celeron E3300 is such a cool running chip even this 3.4ghz overclock shouldnt stress the processor too much and as long as you have decent cooling as directed at the start of this question you shouldnt have any problems
lets remember the E3300 comes from the wolfdale family which are manufactured using the super efficent 45nm(nanometer) fabrication process and because of this speeds of 4ghz shouldnt be out of the question... however top of the line cooling should be used when attempting speeds of 3.8ghz to 4ghz
5) so you have run stability tests at 266mhz(3.4ghz) and they all look good....... now to be honest thats as far as i would go ...... from 2.6ghz to 3.4ghz is a impressive overclock any day of the week.... however if you want to try for higher speeds then voltage adjustments may be required
so thats were i will stop... however if you want to try for 4ghz you should first have good cooling ( a water based cooler like the corsair H50 or H70 ) ...... using a stock cooler is recommended for any overclocking..... and a mediocre 3rd party cooler like the freezer 7 pro is ok for the above overclocking to 3.4ghz
6) to overclock to 4ghz you need to
a) change the bus speed (cpu frequency ) to 320mhz
b) the vcore to between 1.5v and 1.6v ... however tempertures will rise significantly and should even out at around 70 to 75c ......
