You ran memest 86 times, was this using only one stick at a time?
How long did you run memtest?
Did you check the voltages, and compare to what bios says?
Have you tried running one stick of ram, to see if you get the same
error?
Have you tried using a lesser vid card? Could be a power thing, Im leaning
toward ram, but Im not to impressed with raidmax psu's, this is just
my opinion here...
