Intel definitely should release another BIOS update to address this problem!
GeForce 700 Series is not an uncommon hardware, and other board I tested worked perfectly except for DX79SR.
I had problem on this board with my OCZ Revodrive 3 on PCI-E, it took months to actually resolve the problem, while I tested on other board that it was working perfectly fine.
I tried to purchase the best hardware that I could afford, never imagined that the most problematic hardware was from Intel. I've read that Intel is phasing out in motherboard manufacturing, but it shouldn't simply ignore the products that already produced!
This is a complaint, but I look forward for improvement in product support.
