An update from GIGABYTE brings more success after having already achieved a world record 2080MHz overclock using some Micron DDR3 memory in conjunction with their new P35T-DQ6 motherboard.
They've managed to squeeze some more out of the platform, with the memory now at 2200 Mhz, and also the FSB hammering along at 549.99 MHz.

The results were provided both in this powerpoint file and also as an entry in the official CPU-Z database.
