Boost your supported Mac Pro's performance with the 512GB DDR4 2933 MHz LR-DIMM Memory Upgrade Kit from OWC / Other World Computing. Delivering speeds up to 2933 MHz, this 4 x 128GB kit is a memory upgrade designed to improve your computer's start-up times, overall responsiveness, and ability to handle data-intensive applications. ECC (Error-correcting code) technology enables the modules to detect and correct the most common kinds of internal data corruption. The modules are buffered, feature a CAS latency of 21 and a power rating of 1.2V, and work on systems with 288-pin DIMM slots and a DDR4-enabled chip.

Note: Do not mix R-DIMMs and LR-DIMMs. Mixing R-DIMMs and LR-DIMMs will result in a memory error flash of the status indicator light when you turn on the Mac Pro.

I moved my original 8GB to bottom two slots and added these two 16GB memory to top two slots for a total of 40. There are installation videos online. The trickiest part is you place the screen down so you need to protect the table with a towel to protect the screen. 5

Easy plug and play upgrade for a fraction of what Apple charges. 5

installed these into a razer pro 17 because Razer only gives you 16gb. So i went with OWC and its working great. 5

Like most people here, I decided to buy a 3rd party RAM instead of making the purchase directly from Apple. B&H delivered on time and I was more than happy to install these babies on my newly purchased iMac. One or two apps became sluggish post installation so I simply switched the installation slots and that did the trick. I'd definitely recommend it. 5

I added this memory to a new iMac. The additional memory was recognized immediately and has performed flawlessly. I would highly recommend OWC as your memory upgrade of choice. 5
