Lenovo ThinkAgile server memory upgrade

This 64 GB DDR4 module runs at 2933 MHz with CL21 latency and 1.2 V operation. It uses a 288-pin ECC registered RDIMM form factor built for Lenovo ThinkAgile systems with second-generation Xeon Scalable processors.

Suits ThinkAgile VX3320 VX3520-G VX5520 VX7320-N

Buyers needing unbuffered desktop RAM or non-ECC modules should look elsewhere. This registered ECC DIMM will not work in consumer motherboards and cannot be mixed with unbuffered memory.

Single 64 GB registered ECC DIMM at 2933 MHz

The module replaces Lenovo part numbers 4X70V98063 4ZC7A08710 and 4ZC7A08744. It is backward compatible with 2133 2400 and 2666 MHz bus speeds. The 2Rx4 rank organisation and lack of heat spreader match the original server specification.

Questions about this item

Will the 288-pin DDR4 RDIMM fit the memory slots in my Lenovo ThinkAgile VX5520?

Yes, this 288-pin DDR4 ECC RDIMM matches the slot keying and form factor used by the ThinkAgile VX5520 and the other listed Xeon SP Gen 2 models.

Do I need to populate specific DIMM slots first when installing this registered ECC module?

Install modules in the slot order shown in the ThinkAgile service guide — usually the lowest-numbered slot per channel — and never mix these registered DIMMs with unbuffered memory.

If a memory error appears years from now, is the module replaced under the OWC lifetime warranty?

OWC provides a limited lifetime warranty with an advanced replacement programme, so a defective module can be swapped without waiting for the original to be received.
