Summary: Received board in a timely manner. Installed motherboard. No boot. After much diagnostics found out A1 A2 memory slots not functioning, had to run board on B1 B2. Could not run dual channel. USB 3 no faster than USB 2. Hot Swap function not working. Sent board into Asus for warranty repair. Quality control at Asus lacking.
Summary: In the first place this is an excellent mother board. But the box for the Asus P8Z77-V LE Plus contained a Asus P8Z77-V LE driver disk, the wrong disk which does not load the drivers. Talking with Asus support was useless, the did not have the right disk or did not understand the problem. I am left without enabled USB and LAN etc. functions so no Internet access. If this cannot be resolved the board will be returned.
