Do these bioses have speed-step enabled (lower frequency / volt on idle)?
Also will the 290 reference cooler be able to handle the extra heat?
Yes these BIOS have the speed step, they clock down to 300mhz on idle. Initial tests with the 390x MEM MOD BIOS on my 290s, they were actually running cooler with reference cooler.

I can boot up fine using the Intergrated Graphics but as soon as I try to boot up with my GPU it just won't boot at all. Without it being able to be on when I boot I can't see how I can flash it with my old working BIOS which I made sure to save just in case.
So any ideas? Serves me right for forever tinkering with stuff when it's working fine
This is where the BIOS switch comes in handy also, switch it to the working BIOS on boot, then when you get to atiflash, move the physical switch on the card to the bad BIOS position and reflash, should work.
