It doesn't matter. If you changed the fan speed even, the original BIOS dump was half the size of what it should have been so it didn't matter if you OC'd or not - all you had to do was change the BIOS and back to the wrong file.

Either way, it seems like a lot of those that were bricked were fixed as the correct size (1Mbit) is now being used. Obviously the ones that truly weren't touched and died have to be investigated or RMA'd, but it looks like those who played with the BIOSes early no longer have to worry as the fix has been put up.
