can anyone tell me how to overclock my amd athlon xp 2400+, i overclocked my vid card but i am having trouble finding a program to overclock my cpu..help please?

It's difficult to answer without knowing the make/model of your board. And the PC2100 will limit your results. I'd say at best, you're looking at 2.25GHz (15 x 150MHz) if your board & RAM can handle it.

"OS: windows vista CPU/Ram: pc 2100 512mb" If you are using windows vista, then it is better to get at least 1GB RAM rather than thinking about overclock assuming you want better performance...

my motherboard is an msi 6390..and yea I have been thinking about getting a 1 gb stick of ram..soo are there any programs that I can use to overclock it? cuz I can't change anything in the bios ...

and btw,where would I go to put in(15x150mhz)? custom: windows vista msi 6390 board amd athlon 2400+ WD 320gb 7000rpm hd pc 2100 512mb ram 500w ps bfg geforce 6800 oc

Yikes! Crappy board with a crappy BIOS. You can try overclocking thru software, but don't be surprised if the overclock programs won't work with Vista. Vista shouldn't be your primary OS anyway. Do a search for SysTool, SoftFSB, CPUFSB, or ClockGEN...maybe one of them will work. My suggestion is to get a decent board, or go back to XP, or both.

Even with software overclocking, the best you might expect is about 140Mhz. That's right at the speed of a Tbred 2600+. The only performance increase you'll see is in benchmarking programs...nothing that relates to the real world. Crappy motherboards are just that. I own three of 'em and although I can make a 2600+ out of a 2400+ or a 3000+ out of a 2800+, nothing really changes. Skip
