How safe is it to bump up the FSB?

I just got the Corsair XMS 3200 Low Latency XL at 2-2-2 5. The Corsair website said the pair would be stable at 500Mhz... My question is if I set my FSB to 250, would it be safe for my ram and my CPU (don't know if FSB affects CPU temp), or would they over-heat? I'm using Thermaltake POLO 735 Extreme 3 in 1 CPU Cooler for my CPU, and the rest of my system is listed below...

if you monitor your temps you shouldent have a problem with that RAM it says 250MHz but chances are it can go a good deal higher then that. ive had my 200mhz PC3200 running at 240FSB @ 2.9vdimm just fine still 1:1...and upping your FSB wont affect your temps but ull need to up ur Vcore which will.

Theres almost *no* chance in you damaging the RAM by upping the FSB only. The worst thing to happen is a BSOD, or your PC not booting. Just get out the BIOS battery then and retry.

More voltage will be needed for a higher overclock, but untill 3.2vdimm i would call safe.
