Hi there, I have a 2.2ghz i7 mbp and am looking to upgrade ram. What kind of ram would i be looking at? besides DDR3 PC3-10600 1333mhz, is there anything else i should be paying attention to? for example, would these be a good fit for the mbp? http://cgi.ebay.com/8GB-2X4GB-DDR3-...ultDomain_0&hash=item20b682b7b9#ht_1558wt_907 any specific brand i should be looking at? or just anything that works? thanks for any help.
