After some pretty decent testing, I can confirm pretty conclusively, that on MY WIN, turning on ram timing to fast from typical results in the driver crash. I made the adjustment and then wanted to test MC5 while waiting for my sandisk 128 to copy to the new lexar 128 (which by the way is fooking slow as balls in the win for no apparent reason, sticking with the sandisk). MC5 was the first and only game to crash, and it would crash within 30 seconds of joining an multiplayer match, consistently (read every single time). I changed the ram setting back to typical, and was able to play a full 10 minute match with no issue. Turned it back on, crash. Turned it off, played another full match.
I hope this helps some of you, if you're experiencing the video driver crash, please try changing the ram setting from fast back to typical if you changed it and assumed it had no impact.
