I've got an AV8 with 2X512 of Corsair VR in dual channel. It runs PRIME and SuperPi to 32M with zero errors, but in normal use the board is unstable and I think (hope) the problem is my PS. I have an Antec TP430 which is about 2-3 years old and only has 18A on the 12v rail. I've got an OCA Modstream on the way so I'll know more later next week.
