Frequently Asked Questions

What is the difference between 4ZC7A08710 and 01KR356?

Both are Lenovo 64GB DDR4-2933 ECC Registered CL21 Dual Rank x4 DIMMs — alternate part numbers that may differ in DRAM manufacturer or specific server model validation. Verify from Lenovo's compatibility matrix.

Is a 64GB Dual Rank x4 RDIMM the same as an LRDIMM?

Not necessarily. 64GB Dual Rank x4 RDIMMs use high-density 32Gb DRAM dies and are true RDIMMs (not LRDIMMs). Verify the exact module type from Lenovo's specification sheet for the 4ZC7A08710.

Is this compatible with non-Lenovo servers?

This is an OEM Lenovo ThinkSystem RDIMM validated for ThinkSystem servers. Compatibility with non-Lenovo servers is not guaranteed.

The Lenovo 4ZC7A08710 delivers 64GB of DDR4-2933 ECC Registered server memory in a dual rank x4 configuration — validated for Lenovo ThinkSystem servers requiring high-capacity DDR4-2933 RDIMM for enterprise workloads.
