The most aggravating experience in motherboards I've ever had - STAY AWAY FROM THIS BOARD
17 November 2013
Summary: I've been through 3 of these mobo's and am yet to have one work when fully populated with memory. We had Asus on the phone with every install and verified all the other components were good but once the memory was fully populated with 64GB it wouldn't even make it to POST. After spending this much on a mobo, one would expect at least one of them to work. Apparently the problem is rampant in this design as we had 3 in a row with the same problem.
Summary: So far, I'm not impressed. After buying this to create a heavy duty desktop, a larger-than-normal full tower case (Assa 9000) and a buncha other stuff, I found out in the manual, and not on any website and in very small print that the board had driver issues with Windoze 7 Pro. Seems the drivers aren't compatible. Then I found out that it needed a different power supply. An email to Corsair helped with that.
Summary: I purchased this motherboard first at Newegg, but they shipped me a dead one, and then tried to say that I bent the pins on the motherboard as the reason why it didn't work, which would have been almost amusing if it wasn't so insulting. I was putting together a dual Xeon E5-2620 system, and I liked the idea of being able to put a lot of RAM on the board.
