Hi there, a while ago I poped on here to ask advice on some components, when i was purchasing my 2nd gaming computer. I ended up buying:

Intel Pentium Bundle Including pentium Dual Core E5200 Retail Box Processor and Asus P5KPL-AM Motherboard.

This was because a lot of people that replied, said its a great CPU for overclocking, so this persuaded me. I have had the computer for a while now, and want to overclock. I have a few questions tho.

1. My motherboard can overclock correct?
2. do i have to unlock it, or do anything special to tweak the settings for overclocking?
3. What do i change?!!?!, are there any easy to follow guides? or could someone explain, i know a lot about computer hardware, but have never overclocked.

I dont want to try and get it to 4.0ghz like i know some people have managed, and i know its down the actual CPU, because every1 is different. But im at 2.5ghz and would like to get to 3.0+

Any Advice would be helpful.

Thanks in Advanced, Dan

Im not sure I'd buy into socket 775 now, but at the time when I got mine, they were great. For £52 13/14 months ago, with none on the forums (that Ive come across) doing less than 3.6ghz they were a very good chip. 8400's were £130+, but did clock 10% higher on average, and the cache did give them a >10% boost too.

The speed gain for a 7000 series wasnt really worth talking about, and they wernt clocking much better than the 5000 series. So the choice was 5000 cheap mobo and mem, or go AMD PhenomIIx3, which was a more expensive route, but very viable. 3rd choice was the old q6600 chip which was good value, but you couldnt necessarily skimp on your 775 mobo as much.

Cant remember mobo names from >1 year ago, but yeah, its not an OEM (Dell, packard bell etc) board so it will.

2. do i have to unlock it, or do anything special to tweak the settings for overclocking?

You need to get a couple or more utilities to check things are working ok. These are CPUz, Intel burn test, and prime95 for testing chipset overclock stress.

Whilst its going to do 3gh on stock voltage, you will need to increase the default voltage to hit 3.6+. The odd one or two original stepping will require the full 1.41/1.42 volts to hit 3.6. The newer stepping (9 months ago and newer) will do pretty much an extra .2 on average, and may do 3.4 on stock.

Its sometimes good practice to learn what all the settings in the mobo bios are, and try to turn most of the 'auto' settings to a specific figure. Especially for 'auto' voltages.

3. What do i change?!!?!, are there any easy to follow guides? or could someone explain, i know a lot about computer hardware, but have never overclocked.

You need to go into your motherboard bios and change at least 2 things. First, you increase the front side buss speed from its default 200 (ie. 800 fsb = 200 quad pumped) up to 240 to hit 3ghz.

On many mobos that might result in the memory being also overclocked 20%, so you might very well have to change the memory divider settings. Most bios dont tend to help you out by calling things the same name people do on overclocking forums, so dont get fixated looking for the words "memory divider" etc.
