need to go higher?

I bought a new rig & am wondering how much higher can i go with it. I am running thermatake volcano.

Specifications
E8500 Processor
Motherboard 790i
Video card 9800gtx
Ram 2gb ddr3

Unless your computer becomes unstable you can keep on going but see that the temperatures are low & voltages are not very high or until you hit a fsb wall would be fine.

At 1500mhz fsb it seems to be stable but above that it either restarts continously & windows cant be loaded properly & am only able to play low end games.

I think the motherboard is not able to handle it properly? Do you know about the maximum FSB report on this motherboard?

The maximum rated fsb is 1800mhz i think & it supports 1500 mhz cpus like the qx9770 & it also supports the ddr3 2ghz ram that i have with overclocking.
