I started a thread at the OCZ forums stating that my OCZ platinum XTC 6400 rev2 2gb dual channel 4-4-4-12 sticks would not oc to 500mhz 1:1 FSB with my rampage board, but did with my GA and MSI P35 boards. They claim that the rampage boards can't hit 500fsb, and that's a bloody joke. After trying all kinds of settings that they suggested and none of them worked, I concluded that the 6400 OCZ rams are too old for x48 chipsets, and will not OC very high on a rampage board. They got furious with me, getting very aggressive and telling me that their ram is completely fine with the rampage boards. Yeah maybe at stocks speeds, sure. but who the hell is gonna run stock speeds on a rampage board? anyways... None of the OCZ guys had a rampage board, or tested one so none of them can say what's good for the board and what's not. In conclusion, they deleted my thread off their database. Clearly, they don't want people to know that their most famous commonly sold sticks do not run well with the rampage board. So i'm just giving you guys the heads up, OCZ is false advertising. Oh and I forgot to mention, none of the OCZ rams are listed in the rampage's user manual under memory compatibility!
