32GB DDR4 2933 ECC RDIMM

This 32GB registered DDR4 module runs at 2933MHz with CL21 latency and 1.2V operation. It uses a 2Rx4 organisation and fits 288-pin RDIMM slots in Lenovo ThinkSystem servers. ECC and registered buffering protect data integrity in multi-socket configurations.

Suited for ThinkSystem capacity upgrades

Administrators expanding memory in qualified Lenovo ThinkSystem platforms will match the 4ZC7A08709 part number directly. Systems that require unbuffered UDIMMs, a different rank structure, or non-ECC modules cannot use this RDIMM.

Single 32GB 2Rx4 rank

The module presents one 32GB rank pair in a 2Rx4 layout, so the memory controller sees two logical ranks per channel. Planners must verify the platform’s maximum rank-per-channel limit and qualified vendor list before installing multiple units.

Questions about this item

Does the 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the module uses the standard 288-pin DDR4 RDIMM form factor and 1.2 V operating voltage required by compatible Lenovo ThinkSystem servers.

What is the correct orientation when seating the 2Rx4 registered module?

Align the notch on the gold edge connector with the key in the slot, press firmly until both retention clips click, and verify the module sits evenly.

When should the ECC registered memory be replaced?

Replace the module if system logs report uncorrectable ECC errors, the server fails memory self-test at boot, or the 32 GB capacity no longer meets workload demands.
