Summary: I don't think I've ever had a motherboard with so many problems since day 1. Intel RAID has all sorts of issues. If using RAID, it has a nasty habit of changing the hard disk mode after BIOS flashes, so that your computer won't boot.
Summary: This DZ68DB board was never designed for the i7 processors. I found this out the hard way. This purchase is part of a new computer build with the i7-3770K processor and 16 GB of RAM. I am not a gamer, but I use graphics heavily for Autocad and other design software where 3D capability is needed.
Summary: A total loss of this card .... the seller sent a motherboard that does not work .. The BIOS does not boot in any way or form .. Everything was installed correctly. Memory, processor, hard drive, video card, power supply certified. The card only starts but crashes at 3 or 4 seconds. .
