no option in bios to overclock (phoenix bios)
You could try this:
1. Download SetFSB
2. Set clock generator to RTM876-665
3. Click "GetFSB"
4. Move to 65, click setfsb
5. Move to 75
6. Click setfsb
2.964 GHz (3.0GHz basically)
I DO NOT RECOMMEND GOING OVER 75 (2.9Ghz)!!! My system blue-screened like 7 times already trying it out. Just a warning.
The move to 65 helps against crashing during the overclocking of the CPU. I assume signal skipping of some sort might be a cause, crashed on my a couple times jumping straight to 75.
