You can do a simple overclock by increasing your fsb, provided your bios or motherboard allow changes. You wont damage anything. Do you have your mobo manual ? if so look and see if your able to change the fsb.

If you can just change 1 or 2 mhz at a time or the smallest increment allowed each time you increase the fsb go into windows and run a bench mark like 3Dmark and see if it will make it through without crashing. when it crashes just back the fsb down to the last setting that made it through.

does that make sense ?

once you get the max fsb that will work, you can tweak your memory setting if you want. the cas latency is the most important yours is probably at 2.5 or 3 changing this setting makes a big difference in memory performance. test it the same way running 3dmark.

There all alot of other ways to OC too but take things slow. especially if you have a standard heat sink or poor case cooling.

I just went to the MSI web site and they have a utility "Fuzzy Logic" that allows you to change the fsb and other settings from windows that might be the easiest way to go.

Thanks for your advice much appreciated.

Will try what you suggest and see how it goes.

Thnx again

cheers
