MSI - K7TM Pro problem ??!!??

I bought two of these boards in the summer, and both of which allowed me to change the FSB speed, from the standard 100MHz to around 110MHz, which was great. So when I decided to build my third personal computer, I went for exactly the same motherboard (MSI K7TM Pro 6340), believing it was a good board, and would satisfy my small overclocking desires. However, even though this m/b is exactly the same model/revision as the other two, it would not allow me to overclock via the FSB. It came with the same BIOS version, so it gave me exactly the same options to play with, but would never go over 100MHz. I can select any higher frequency (ie. 104, 106, 107.... etc) and regardless of the setting, the board will always boot at around 33MHz, no joke. However if you select 102MHz FSB, the board will simply refuse to boot at all.
My first thought was that something connected to the board was stopping it from overclocking, so I decided to swap every single component from a my overclockable computer, including the CPU, into this un-overclockable one, but it still failed to overclock, eliminating all components apart from the motherboard itself.
I've looked on their website, spoken to technical support, downloaded various BIOS updates, all to no avail, the board will simply not overclock.

All three of my computers have 800MHz green-core Thunderbirds in, which are not great overclockers themselves, so I really enjoyed that little extra boost the FSB increment gave me. All three of these CPUs were ordered together, from the same company, and had a default voltage of 1.8v, which didn't exactly give me a lot of room to increase it further. Is there anyway of doing a voltage modification on this particular motherboard?

Thanks in advance for any help you may be able to provide me with, concerning the FSB problem, or a possible known voltage modification.
