I'm looking to add 3 4GB modules (12GB worth) of Kingston memory to a brand new 3.2GHz Quad-Core Intel Xeon Nehalem Mac Pro. On Apple's website it says "Depending on the processor you choose, the single-processor Mac Pro uses the following types of memory: 2.8GHz and 3.2GHz quad-core processors: 1066MHz DDR3 ECC SDRAM." Is this correct? http://www.cdw.com/shop/products/Kingston-memory-4-GB-DIMM-240-pin-DDR3/1710696.aspx I have to order this through CDW (office account). Thanks.
