32GB DDR4 ECC RDIMM for Lenovo ThinkSystem

This 32GB DDR4 2933MHz ECC Registered RDIMM is built for Lenovo ThinkSystem servers based on Xeon SP Gen 2 processors. It suits administrators expanding memory in SD530, SD650, SN550, SN850 or SR630 platforms. The module will not work in standard desktop computers or with unbuffered memory.

DDR4 2933 registered interface limits

The RDIMM operates at 1.2V with CL21 latency and a 2Rx4 rank structure. It is backward compatible with 2133MHz, 2400MHz and 2666MHz DDR4 buses. Registered ECC memory cannot be mixed with unbuffered modules and requires a platform that supports registered DIMMs.

Verify server model and memory configuration

Confirm the exact ThinkSystem model matches the listed part numbers 01AG632, 4ZC7A08709 or 4ZC7A08742. Check that the system uses registered ECC DDR4 and has free 288-pin slots. Ensure the memory population rules for the specific Xeon SP Gen 2 platform allow the desired capacity.

Questions about this item

Which capacity should I choose for my Lenovo ThinkSystem server?

This module provides 32GB per DIMM; populate the available slots on your SD530, SD650, SN550, SN850 or SR630 to reach the total memory your workload requires.

What does the 2933MHz rating mean once installed in a ThinkSystem server?

The module runs at DDR4 2933 CL21; if the platform operates at 2133MHz, 2400MHz or 2666MHz the DIMM will downclock automatically to match the system bus.

Is this a standard DDR4 DIMM or a registered ECC type, and what does that limit?

It is a 288-pin ECC registered RDIMM (2Rx4, 1.2V) designed for Xeon SP Gen 2 servers; it will not work in standard desktops and cannot be mixed with unbuffered memory.
