I really like this board, but I have had some weird problems with it so far. On reactive mode - I pressed Fn + right arrow to adjust the timing, and the keyboard crashed. LEDs went totally blank, and was unresponsive. I had to reboot to get it back (yes I tried unplugging it and re-plugging it in). The keyboard is plugged directly into the computer, and not into a hub. I'm running Windows 8 x64 on an i7 2600k w/ 16 GB of RAM. Custom built PC. Never had a keyboard crash before.
Anyone else had any problems like this?
