I'm having a strange issue on my board, both BIOS chips showing the little red light in the bottom right hand corner of the board with no postcode when using an APU. I don't have any other CPU at hand at the moment, I flashed back both chips to the latest BIOS and it seemed to go through o.k. but then I got that LED. Hopefully I didn't kill the BIOS chips or something, this was just the latest retail BIOS, nothing fancy.
Not every dogpile is for BCLK and therefore not every dogpile requires DB work. In fact as far as I know, this was the first BCLK dogpile. Others I remember are Aquamark and x265.
