Boost your supported Mac Pro's performance with the 64GB DDR4 2666 MHz R-DIMM Memory Upgrade Kit from OWC / Other World Computing. Delivering speeds up to 2666 MHz, this 2 x 32GB 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 registered, feature a CAS latency of 19 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.

Most unopened items sold by Melrose Inc. in new condition and returned within 30 days will receive a refund or exchange. The return window for items sold online begins once the order has been invoiced. Invoicing happens when any part of the order is shipped, delivered by a courier service or made ready for pick up.

Software is not returnable and not refundable. All sales are final. This is generally part of all webcarts selling software. It is buyer beware. The reason for this is once an end-user customer sees a License Code then that code is 'spoiled' because they can use it to gain access to the software.  Once a License Code is registered by a customer that product is available to that customer and therefore the code cannot be returned.
