MSI X99a 7 Gaming board. Replaced three times. both Bios got locked. unexplained restarts and shut downs. issues with Memory. on the Third time. i just decided not to install the replaced board and purchased Gigabyte G1 Ultra Gaming. Solid. none issues at all with the same parts. Last time i purchase MSI (the second RMA'd board were replaced by non new board, same they did with the MSI HD290X i paid premium for brand new MSI Premium parts which in the end were replaced with fixed MSI parts).
AMD AM4 boards are severely lacking here guys, I get some might want to build AM3+ or HT with FM2+, but come on, not true enthusiast would do so, they'd either wait or build Intel. You have Intel well covered, why not do the same for AMD? Waiting for Ryzen3?
