💻 Upgrade your Mac Pro 2009-2012 'Nehalem' & 'Westmere' with High-Performance OWC 16.0GB (2X 8GB) DDR3 ECC-R PC10600 1333MHz SDRAM Memory Review

I used two of these kits to give my Mac Pro 5.1 a major overhaul from 32GB to 128GB including NVMe and SATA III SSD+ high performance graphics card. The illustration shows new memory cards installed in the processor bay. Installation was quick and the memory worked great the first time.

sold by OWC) but this detail is easy to overlook. OWC sells the correct upgrade which I recommend. Compatibility note aside, this is a great product. Stable error-free storage, very reliable. I've been using OWC RAM on my Mac Pro workstations for 4 years with no problems.

Installed it on my 2 x 2.4GHz 6-core Mid 2012 Mac Pro with no issues. Shut down, removed the old memory, installed this memory and turned on the power. I've been using Pro Tools and PreSonus Studio One Artist to process large recording sessions for almost 2 months now and have had no problems. Definitely recommend this for a memory upgrade on this machine model.

It was easy to install the mid 2010 MacPro 5.1 and it would be easier if I realized I could take out the entire CPU tray. It is important to install in the correct order. Just follow Apple's instructions. I am very happy with the installation and performance.

They said this is for 2010 models, but that's not true. It's been a month and you still haven't refunded my money even though I sent the cards back. It was the waistline of time, and now money. Many Thanks

I placed two orders of 32GB RAM each and both arrived quickly and have been working fine for weeks. Nice to have 64GB of RAM! My first computer, a ComPal 80 (Poly 88 in a larger box with a fan - that was around 1977) had 12K of RAM! God, how times have changed. ;-)
