Ok so the board was working good for a few days and then today it started having problems. The most concerning is that the system will shut down without warning (no bsod or error messages, event viewer is useless). This is all at stock optimal settings. Secondly, the device panel is constantly refreshing and I hear the USB chime as if it keeps searching for a new plugged in device. Thing is that I unplugged all external devices yet it persists. I also flashed it to the newest bios + cleared cmos twice now to no avail. Here's my setup:
Windows 8.1
Asus rampage V on latest bios with optimal settings
4 x 4 Corsair Vengeance 2666 MHz Ram
Intel 5820K processor
2 x EVGA GTX 980 SC GPUs
Samsung 840 Evo 500 GB SSD
1 TB Seagate HD
Corsair H100i cooling (with corsair link connected)
Corsair Ax1200i PSU (the older one that didn't have the OCP firmware)
Is this a faulty board? I requested an RMA with Amazon regardless.
Edit: Device manager is showing this now:
