Lenovo ThinkSystem 64GB 4Rx4 DDR4-2666 3DS RDIMM TruDDR4 Memory

Four ranks and stacked chips: the Lenovo ThinkSystem 64GB 4Rx4 DDR4-2666 3DS RDIMM, part number 4ZC7A08716, is built for capacity. As a 3DS module, its memory chips are stacked, allowing 64GB on one DIMM.

It is a registered ECC module running at 1.2V with a data rate of 2666 MT/s. A 4Rx4 layout means four ranks of x4 devices, and some servers limit how many such modules can sit in one channel, so check your platform's population guide.

Buyers use 3DS modules in servers built for large memory footprints, such as databases that hold their data in RAM or hosts running many virtual machines. The module also works as a replacement for a failed one in a server already using this type.

It is offered refurbished with 1 year or 3 years of warranty, and used with 90 days. No new offer is listed. Include your server model in an RFQ for 4ZC7A08716 so we can check 3DS support.
