I am looking to order memory upgrade kit for my new MACpro. (finally pulled the trigger today with free itouch option ) Crucial vs OWC Crucial: http://www.crucial.com/store/mpartspecs.aspx?mtbpoid=5B2766DBA5CA7304 OWC: http://eshop.macsales.com/item/Other World Computing/64FB2GD4GBK/ My question is, if you look at the crucial site, there is a product details tab where it talks about energy-efficient memory 1.5v. Has anyone order this memory from crucial? Just wondering if they are 1.5v... The product spec does say 1.8v... OWC's memory shows 1.8v in the spec... I would love to get 1.5v if possible... any thoughts?
