Am I Going to Have Problems?

I wanted a mild kick out of my system. I increased the FSB to 220 MHz but left everything else alone. The system now shows the CPU operating at 2.42 GHz. I have been running this way for about three weeks with no problems. Specs are as follows:

Abit KN8 SLI
4400 X2 (now at 2.42 GHz, up from 2.2 GHz stock)
2 x eVga 7800 GT (517 edition)
650W PSU
2 GB Kingston memory (4 x 512 MB sticks)
Zalman 7700 CU CPU cooler (CPU temp is 27 C at idle at rarely rises above 35 C under load)

I am just wondering, am I going to damage my system by only increasing the FSB?

Your Fine If Its Hasnt Had Any Problems Just Make Sure Ya Keep It Cool
