This is SO embarrassing - especially for how long I have been doing stuff like this. 
I upgraded the bios on my system last night. Why? Dunno, just felt like it as I was doing lots of other stuff.
However I forgot to stop the cmos being refreshed.
Yep, I have lost my sodding profiles.
Does anyone have the 4ghz overclock profile for this;
*OVERCLOCKED* Intel Core i7 920 D0 Stepping (SLBEJ) 2.66Ghz @ 4.00GHz Max / Gigabyte EX58-UD5 Intel X58 Motherboard / Corsair 6GB DDR3 PC3-12800C9 1600MHz DDR3 Bundle
4.00GHz Overclock
I have phoned OC, but they don't have one for this board anymore and they suggested I post in here.
Thanks
Mike
