These memory modules work great, just as expected!
December 7, 2017
I bought these memory modules at OWC after I had a very good experience with buying at this website some time ago. The modules are working great and were very nicely packed for shipment to The Netherlands. The order took only a few weeks from door to door, so even the shipment was organised very well. The only minor thing why I can not give 5 stars is that the track and trace is only working to follow the shipment in the US after that it is waiting and hoping because there is no tracking info available. Beyond this minor thing the product is excellent! I would recommend this item to a friend!

When it comes to memory, what can one say? It either works or it doesn't. OWC memory works. When I maxed out the memory then I never have an issue with performance. My Mac really hums along nicely. I would recommend this item to a friend! This review is from 32.0GB Mac Pro Early 2009 Memory Matched Set (4x 8GB) PC-8500 1066MHz DDR3 ECC-R SDRAM Modules.
