Unable to Overclock, Award Pheonix Bios v5.5 (help pls)

I have a MSI 865GM2 - 5 (MS-6743G) board.
Northwood 3.0Ghz 800FSB
Radeon 9600 128mb


I tried doing all the research i could and am unable to find out how to overclock my CPU.

In all my previous BIOS's from other motherboards, ive had the possibility of adjusting the the FSB/hertz range in the "FREQUENCY/VOLTAGE" option in the BIOS, however in this one (Pheonix version 5.5) it only has these 4 options: (as in picture):

Auto Detect PCI Clock
Spread Spectrum
AGP/PCI Clock
AGP Power Voltage

Ive played with the Spread Spectrum option and it doesnt change anything.

Does anyone have any ideas on how to overclock on this motherboard?

Thanks.

In the BIOS there should be a Frequency/Voltage option. Go into that menu option and then you have to specify the Frequency as manual or user control. Then the fsb should be adjustable.
