I have a 2010 Mac Pro with a sad 6GB of RAM. I went to amazon search for 1066 MHz DDR3 ECC memory module and some how bought Kingston Technology HyperX Blu 8GB 1333MHz DDR3 Non-ECC CL9 DIMM I really should of payed more attention. Will it still work? Should I cancel the order? It was a good deal for RAM, I Edit videos and photos CS6 and Final cut, and Aperture.
