Opened a new thread because there's information in other threads, but confusion between last years and this years models... The 2012 MBP (non-retina) specs 1.35v RAM and OWC sells a 16GB kit with that voltage. Corsair Vengeance has one at 1.5v, but I can't seem to tell if auto-switches to the lower voltage. Anyone know what the difference is, if any, in terms of compatibility and performance? These new MBPs run cooler, quieter and with decent battery life. I don't want to do a thing to jeopardize that!
