I have used this same memory on 6 EVGA's, 2 Stikers, 2 Gigabytes 680i's, 2 Abit 680's and a foxconn 680i lt. Never any shutdowns. I stated in previous post it even shuts down at 700mhz. It's sold as 1200mhz memory so 700 is way under clocked. It also shuts down with the mushkin 2x2gb kit installed. I've used that memory in half of the above boards with never any issues. It shuts down at default settings as well, that is no overclock on memory or cpu. It runs memtest86 at better than rated timings with no errors. If i was basing stability on just one of the above statements i could understand why you would say it could be memory. but taking all of the above statements in to consideration, I can say with certainty that memory is not causing the shutdowns.
1. Which BIOS? The differences between 0503 and 0504 are significant.

2. Do you have the X-FI installed? If so, remove it and see what happens.

3. Did you do a clean OS install? I have noticed the same issue moving from one 680i board to another.
