can't run stable at 1575mhz with modded bios
Mine goes up to 1650 stable.

Think will be nice to update the 1st post with adding this bios also. Seems quite good. Running for already 4 days stable, without crashes even overclocked to 1150/1575mhz

Try this:

this is modded from a Sapphire HD 7970 3G OC w boost, Hynix AFR.  It should actually work on your 280x as well.
