Asus P8P67 Pro & Corsair DDR3 PC3-12800 CAS9

Does anyone know if there's an issue with the above mobo and RAM where the RAM won't run at 800MHz and only runs at 667MHz?

I built my new PC the other day, and everything went swimmingly, but I noticed that the RAM was defaulting to 667MHz instead of 800MHz. I went into the BIOS and changed the RAM to run at 800MHz, saved and rebooted. It started up, fans spun, gave no video output and no sounds and then switched off automatically. This happened three times in a row before POSTing and giving an error stating the overclock had failed.

Overclock? It's supposed to run at 800MHz...

Any ideas? I did a bit of a Google as usual, and there are some people saying it might be a bug with the Asus board (though they were talking about another RAM manufacturer), but I'm not sure if I should flash the BIOS straight away or if there's any other BIOS settings I should first check/change before doing this.

Managed to get it working by setting the AI Overclock Tuner to run from XMP, it also seems to have changed my CPU from 3.3GHz to 3.7GHz which is nice.
