The VI/O1 Jumper is default at 2.7V for the DDR memory, however, usually DDR memory is designed for 2.5V. This could cause system instability and cause crashes during heavy memory load. This is especially true when I played 3D games. The fix is to remove the VI/O1 jumper, which set the voltage to 2.5v, I don't understand why Asus doesn't even give the option for 2.5V for the jumper setting, and yet clearly stated DDR RAM uses 2.5V in their OWN MANUAL!
This is documented on the A7M266 review from www.lostcircuits.com, which solved the problem I had for 2 months!
Good luck and remove that darn jumper soon!
p.s. I had Crucial 256MB PC-2100 DDR Ram, and on their website it's also recorded 2.5V in specs.
