First off, WELCOME TO THE FORUMS!
Godfodda's article is right on... some other interesting articles you might want to read are here
. This is called the "Beginner's Section", and it has some good stuff to know about how to overclock, and other helpful hints about your computer in general. Another article (in addition to Godfodda's) I think is definitely worth a look is this one
, which was written by one of our Forum Senior Members, Batboy. It is a very thorough article that gives you the do’s and don’ts of overclocking. What follows is basically my own little compacted version of how to overclock, but be sure to read those articles as they have some useful information in them.
Take baby steps... nothing more than maybe 105~110FSB on your first shot. Boot into Windows and run some sort of processor intensive application or burn-in utility for about an hour, and if it's stable, reboot, and try a higher FSB. Basically, this is trial and error. If you go too high and the system will not POST, you must find the "clear CMOS" jumper, and set it so it will clear the BIOS (your manual should have more info on this). This will restore everything to default, but it should let you boot.
You'll want to keep an eye on your temperatures. Make sure they never exceed 50C, and try to keep them below 45C.
If an overclock is somewhat stable, but still gives you some errors, you can boost the voltage, but then keep an even closer eye on the temps as that will raise heat.
Also, you might reach a point at which some of your PCI/AGP cards may not work. Most cards can handle up to a 40MHz PCI frequency well, but after that, start to flake out. Be especially careful if you're using a NIC, as these are known to be very persnickety about high PCI speeds.
Some good programs for burn-in and general system maintenance are Motherboard Manager 5 (MBM5), SiSoft Sandra, Toast, and Prime 95. You can check to see if some of these are available at downloads.com
(I know Sandra is available there), and aoafiles.com
also has some good CPU programs (and other nice, interesting stuff, as well).
G'luck, and report back with your max. speed and/or any problems you may have!
