My bios is 84.00.32.00.68 Is it the latest? Can't really understand from this page.
Also can't get the OSD from OC Guru to work. Soon I'll get over how cool it is to change colours and I'll go back to Afterburner anyway.
My bios is 84.00.36.00.6E
edit: Just tried 130% power. Seems like 1466 Mhz is the best I can do at stock.
