I have here for sale 2 x 64GB (128GB total) of Micron 2Rx4 PC4-2933MHz Registered R-DIMMs for servers or workstations. Suitable for use in the 2019 Mac Pro 7,1

These were installed new and tested working perfectly in a 2019 Mac Pro 7,1, but they have not been used otherwise, so are as new, and are now surplus to requirements for a project.

PLEASE NOTE:
This is server-grade RAM, intended for servers or professional workstations. They cannot be installed in ordinary desktop PCs!
I have a total of 6 of these pairs of 64GB modules listed, making a total of 12 modules (768GB) available
These modules are also listed as 3 batches of 4 x 64GB (256GB) each, or 2 batches of 6 x 64GB (384GB) each.

So do please look at my other listings if the above alternative combinations suit your needs better.

WARNING:
Do NOT mix (Registered) R-DIMMs with (Load Reduced) LR-DIMMs in the same machine, as they are not compatible, and the machine will not boot!

Please feel free to ask questions before purchase, I will be happy to answer as best I can.

Payment via eBay payment options please. Thank you.
