Ok, this is my second set of them, not that the first set went bad. But both the first set and now my second set could not do over 270fsb stably. They always fail memtest86 test 5 at around 98%. Anyone know what settings to use? Also most poeple seem to get stable at 270+, why carnt mine? Am trying to find the max fsb of the ram, so the ht multi is 3x, cpu multi 6x.
