You could get the Crucial's CL10 RAM for less price than this slow CL13 so buying the one in the link would be very stupid.. unless you are planning to keep some of the Apple stock RAM there and just fit up the rest.. but in that case you should go with Hynix CL13 since that is what it has as defaultI think these should be okay then..
