@cowanon @Humpleupagus @skylar @xuya @aes31494 @justnormalkorean @zero AMD gpus are tightly tied to the ram speed, and the ram sticks have to be matched at the factory. Not about to go into details now, but getting two 2 stick packs doesn't work. It does, but doing so wrecks your cpu speed. They may figure out how to make larger or 4x paired sticks in the future, but for now your only option is to get larger sticks.

Get the x series motherboards, definitely.
