|It would help to list your specs as an actual list rather then spreading it out thru the body of the post. It's quite a mish-mash of parts too. You didn't list your RAM specs - DDR2-533, 667 or, 800?|
Anyhow, below is a link to your board, the BIOS will dictate whether you can overclock or not. I downloaded the manual & unless I missed something, the necessary options aren't there. It looks like all you can do is raise the CPU speed by a perecentage - +5%, +10%, +15%. That's not going to get it done. You need to be able to change the memory speed, the CPU frequency (FSB), CPU multiplier, CPU:DRAM ratio, PCIe bus, voltages, Spread Spectrum & a few other settings. You can certainly experiment though.
Your CPU will easily do 3.0GHz (9 x 333MHz) but I don't think you can do it with that board.
