Rating: 5/5 Solid Ram November 26, 2017 Bought two sets of these for my 09 Mac Pro. Now with these; I have more than enough ram for quite awhile! They were good quality and very sturdy looking; just what I'd expect from OWC. Even the packaging was top notch!

They installed very easily just like a dime should. And upon boot; there were and have been zero problems since!

With upgraded firmware they get recognized at the full 1333mhz, but without only 1066mhz.

I would recommend this item to a friend! Customer Videos:
