ok my minds gone blank lets say if my processors fsb speed is 533 mhz then i can only have memory up2 266 mhz ddr right... i was looking at a pentiuum 4 2.2 ghz and it has a fsb of 533mhz but my athlon xp i think only has a fsb of 266 i think or tht could be my Ram plz help i

Pentium's use Quad data rate FSBs, whereas AMD used DDR. Does that help?

i bsaically want 2 know is it the fsb of the processer u use to find out the highest memory u can use? like if i have a 566 mhz fsb cpu i could have up2 pc3200 ram right?

No it's down to the motherboard chipset usually as most boards will let you run RAM at a higher speed then the fsb (asynchronous)

k ive just read about it i lost my memory for an hour so with a 333mhz fsb mobo like the one i have i can use pc2700 ram as its 166mhzand x2 cuz its dd=332 can i ask what is the cpu fsb used for? is it the rate tht it can read the ram memory or something like tht?

In basic terms FSB speed is the speed with which the processor commumicates with the memory and chipset. A multiplier is then put on this which the processor runs at, in this case 166 x 12. Just had a quick check and your MB will support processors with 400FSB i.e 3200+ along with DDR 400 RAM, so if you get yourself some more 3200 Ram and then you can overclock you proccesor by raising your FSB towards 200 from it's current setting of 166 and see how far you get, you may not reach 200 stable but most people seem to hit 190 at stock voltage and not to higher temps, main problem is becuase the multi on these is quite high i.e 12 whereas say overclocking a 2500+ is easier as it's running at a lower mulitplier
