Premium Quality Modules fully Mac Pro Qualified and backed by OWC Memory Lifetime Limited Warranty including Advanced Replacement Program.

These OWC memory modules fully meet/exceed Apple's Mac Pro Quad & 8-Core Xeon model memory specifications. Utilization of qualified Apple Mac Pro Heat-Spreaders, Apple Qualified IDT AMBs, and the best major brand memory components ensure maximum performance and trouble-free operation. Modules are fully tested prior to shipment.


Apple specifically designed the Mac Pro with more space between each slot to accommodate the Apple Proprietary Heat-Spreader for thermal requirements. Use of Apple's spreader solution and the highest grade, thermally tolerant components ensure that these Mac Pro Quad Xeon Memory Upgrade Kits will provide a lifetime of reliable and trouble-free operation.

Apple notes that using parts with a non-Apple standard heat-spreader and which only meet JEDEC standard specifications can result in higher fan speeds due to increased internal temperatures and system controlled reduction of memory performance to prevent thermal overload. OWC's testing has found that use of non Apple qualified spec modules leads to ECC errors and ultimate system lock ups as non-spec modules reach significantly higher temperatures.

Two well known memory manufacturers originally listed their own JEDEC standard modules as being Mac Pro compatible. Within days of doing so, each removed this compatibility support after reports and testing which made clear JEDEC standard modules were not reliable in the Mac Pro. It is very disappointing that many other memory providers continue to list and misrepresent such JEDEC modules (lacking the proper heat-spreader) as being correct for the Mac Pro.

The Apple Mac Pro is an amazing machine. Memory from OWC only makes it better!

Rating: 5/5 New memory works fine June 7, 2016 I bought four 2-GB modules for a Mac Pro (Early 2008), 2.8 GHz Quad-Core Intel Xeon. This was to replace four 1-GB modules which I had noticed were starting to get correctable errors. This replacement also meant that the Mac Pro went from a total of 12-GB to 16-GB.

The task of replacing the memory was trivial to do, and the machine has been working fine with the additional memory.

Rating: 5/5 Got the RAM yesterday and installed it. Works great. November 10, 2015 Thank you for delivering the 4 x 2GB 00 MHz DDR2 FB-DIMMs. We installed them in my Mac Pro today and they worked really well. We also reinstalled the older RAM modules which incidentally, had been incorrectly installed by the vendor from whom I bought the computer early 2008! I wondered why it had been so slow and was only showing 2GB instead of 4GB.

We tested the OWC memory first, and it worked fine, then added back the other modules afterwards. All are working and I now have 12GB RAM altogether. It is like having a new computer.

Thanks also for the instructive video which was easy to follow and helped us to install everything correctly.

Rating: 5/5 now I don't need to buy a new computer August 25, 2015 I have a Early 2008 Mac Pro with a single quad-core processor. It had 4GB of memory, and was very slow due to a lot of disk activity, especially after waking up. It was under a lot of memory pressure, according to activity monitor. So I added 8 GB of memory, and all the spinning beach-ball delays went away. I can now continue to use this 7-year old computer for quite a bit longer.
