Did you see this?
Turns out that some of the users on the Apple Support Discussion forums are finding out that the approved 3rd party memory upgrades are causing instability and lock-ups. Reports seem to indicate that only Apple brand RAM is working properly. Which is fine, if you are drinking the cider and don’t mind paying the premium for the Apple logo (as much as double the street price for DIMMs).
Really? I didn’t even think this was possible to do. And I would be seriously appalled if it is also the case. Like, switch back level of appalled.
Ridiculous.
