I bought a DX79TO on release only to find out the shipping Bios 281, didn't support the i7 3820 CPU. I went through hell to get a 3930 to update the Bios to use thr 3820.
I really like the board and was considering another but this time I have no acces to a 3930 to update Bios. Does anyone know if the newer issues of these boards ship with the latest or an i7 3820 compatible Bios ?
I find it hard to believe Intel wouldn't have corrected this by now.
This thread answers your question about the DX79SI and the 3820
the same applies to the DX79TO. Default BIOS was updated in April 2012 (AA G28805-401), PCH was updated in May 2012 to stepping C1 (AA G28805-402)
