OWC 32GB DDR4 2666MHz ECC RDIMM

This OWC 32GB DDR4 2666MHz CL19 ECC Registered RDIMM is built for Lenovo ThinkAgile servers running Xeon SP Gen 1 processors. The 2Rx4 module operates at 1.2V and fits 288-pin slots in HX1320, HX1321, HX2320, HX3320 and HX3520-G systems. It is not compatible with standard desktop computers or unbuffered memory configurations.

Replaces Lenovo 4X70P98203 and 7X77A01304

The module replaces Lenovo part numbers 4X70P98203 and 7X77A01304 in compatible ThinkAgile servers. Backward compatibility with 2133MHz and 2400MHz speeds allows use in systems running at lower frequencies. The upgrade is worth it when ECC error correction and registered buffering are required for server workloads.

Simple DIMM installation with ECC constraints

Installation follows standard 288-pin DIMM insertion into the server memory slots. The registered design requires a platform that supports ECC Registered memory; mixing with unbuffered modules will prevent boot. No heat spreader is fitted, so airflow across the module must be maintained by the server chassis.

Questions about this item

Does the 288-pin DDR4 RDIMM fit the DIMM slots on a Lenovo ThinkAgile HX3320?

Yes, the 288-pin registered DIMM matches the DDR4 slots used in the ThinkAgile HX1320, HX1321, HX2320, HX3320 and HX3520-G.

What is the correct way to seat the 2Rx4 registered module so the ECC function works?

Align the notch with the slot key, press straight down until both retention clips click, and populate slots per the server's memory-configuration guide for registered DIMMs.

When should the 32 GB ECC RDIMM be replaced if correctable error counts start rising?

Replace the module when the system logs show increasing correctable ECC errors or when a memory diagnostic reports uncorrectable faults on this DIMM.
