Purchased a 2010 Mac Pro 5,1 that came with 32gb of aftermarket Crucial memory. It's a 2 x 2.4ghz Quad Core, so even though it shipped with 1333Mhz ram, the previous owner probably put 1066Mhz in there since that's all it needed (and probably what Crucial recommended). Is there a way to confirm the ram speed before I swap out the CPUs for dual 6-core units? If it is 1333Mhz, would it show itself in System Profiler as 1333Mhz on a 1066Mhz cpu system or would it say 1333Mhz even though it's only running at 1066Mhz? I want to confirm the actual ram speed as opposed to the speed it's running at now on these slower chips.
