OMG, I was using only the 10x multipl. till now with the bios 1602.
Now that I tryed to change it, I see that this bios has this bug.

It will lock your multiplier. Mine is locked on 10x. You can actually change it on bios, but it will still boot with a 10x multiplier. And I have a QX cpu.

Anyone found a work arround for this issue with bios 1602?
Apart from that, I think this is the best bios so far.
