you will need the manual and that long number

- which is that big number at the bottom of the page when you boot up, & which tells you exactly which motherboard it is. You cannot afford to get confused about which one you are dealing with as there can be small but vital differences between almost identical models, so my advice is keep a cool head do some careful research do not be fooled by red herrings.

You need to have that number and try looking for its corresponding manual and/or manufacturer etc so you can find out about the jumper settings for over-clocking the board and chip.

also try running a search on "overclocking celeron" and just reading around the subject, you will find many of your questions answered and some you hadn't even thought of, as there is a large and verbose community dedicated to o'clocking so you will not have any trouble finding out what you need to know.
