Been playing for about a month now without issues. Back on Thursday, 12/31/15, I got a new gpu. It is a used AMD R9 200 / HD 7900 Series. I played close to 30 hours over the weekend without issues.

Fast forward to today. I get a new stick of ram in, taking out my old ones. It is an 8GB DDR3 1600 stick. Install it without issues. Everything seems to run fine. I know my Motherboard won't run it 1600 by default, so i OC'd it to 1600 from 1333. Load FF14 and it started giving me this error every 5 mins or so. (I'm running on D11 Max settings, btw.)

I went back and changed the RAM speed back to 1333 and the errors went away. Don't know if this helps anyone, but if your RAM is DDR3, 1600, try changing it to 1333 and see if that works? Or if your RAM is overclocked, try without?

Figured I'd post just to see if my solution helps anyone. Hope Square or AMD can fix the issues.
