As an outsider, I have to say this looks like a poor show (whether it's OcUK/MSI/The Pope/Whoever's fault). Feel a bit guilty that I posted this on HUKD at the time!
Isn't that defeating the whole point of buying a pre-overclocked card!?
I agree it does seem to be defeating the whole point but the only alternative is to RMA the card and get a refund then buy a real over clocked one for about £100 more - which I do not really want to spend at the moment.
Currently using the tweaked bios is my best solution.
