Pros: Very pleased with the quality and ease of use of this board in my latest build. I'm a long-time ASUS board buyer, first time user of a ROG ASUS board. The quality and solidity of the connectors and heat spreaders on the ROG board is apparent. UEFI BIOS worked like a charm for me. RAID 10 setup was painless, with one hitch (see below). BIOS flashback and two-digit POST code displays are nice touches. Easy one-click overclocking of my Intel i7-3930K hexacore from 3.2GHz...
Cons: Minor con: I am running dual ASUS Radeon 7770s in Crossfire in my two PCI-E slots. The bottom card is right above the Intel X79 PCH heatsink, which tends to run a little hotter than anything else as a result, probably from poor airflow. It would be difficult to mount a fan in there. PCH runs at 102F (38C) idle, 114F (44C) under load. Not worrisome, since the fan suite sounds alarm at 140F (60C) which I have never reached, but I haven't load tested it for an hour yet.
Summary: However, the ROG connect bios updater is impressive and quite easy to do once you understand the procedure correctly. Essentially you down load the bios rom and the bios renamer from ASus. Put the rom in the folder and click on the renamer exe.. it renames the file, you drop the file on a USB flash drive and pop it into the ROG connect usb port and press the ROG button next to the port for 5 secs and release once it starts flashing.
Pros: Overclocking on the board is AMAZING. The bios tweakabilty is incredible.
Cons: Shipped with an old bios that did not support the 2011 chipset. Hence it would not post, nor get video, which would probably account for the majority of these DOA complaints.
Summary: If you have a 4820k, 4930k or 4960x processor you will likely need to update the bios with a flash drive before it will boot, it's not a huge problem it's just frustrating because I was just about to begin the RMA process for the board and CPU before I realized that was the issue, especially since red CPU and Q-LED 00 normally means DOA or motherboard.
Pros: Good board if it has what you want, lots of nice little extra features not found on other manufacturers boards. Not very expandable but what you would expect from an ATX micro board.
Cons: Did not come with a BIOS version that supported many of the LGA-2011 CPUs, so you need to update it. This is probably causing a lot of the issues in many of these recent negative reviews so take that into account(namely the ones where it doesn't POST with a red CPU-LED, and Q-LED 00).
