32GB DDR4 ECC RDIMM for Supermicro X10

This 32GB registered DDR4 module is built for Supermicro X10 server and workstation boards including the X10OBi-CPU, X10QBi, X10QBL-4, X10QBL-4CT and X10SDV-12C-TLN4F. It delivers error-correcting, buffered memory for workloads that require data integrity and sustained uptime. The module is not compatible with standard desktop platforms or unbuffered memory configurations.

288-pin registered DIMM without heat spreader

The stick uses a 288-pin DDR4 RDIMM form factor operating at 1.2V with CL15 latency at 2133MHz. Registered signalling reduces electrical load on the memory controller, allowing larger capacities per channel in multi-socket systems. The absence of a heat spreader keeps the profile low for dense server chassis where airflow is managed by the system fans.

Replaces Supermicro MEMDR432LHL01ER21 and similar

This module directly replaces Supermicro part numbers MEMDR432LHL01ER21, MEMDR432LSL01ER21 and MEMDR432LSV01ER21, extending the service life of existing X10 infrastructure or reducing cost on new builds. The upgrade is worthwhile when ECC registered memory is required and the target board appears on the validated compatibility list. It will not work in systems that only accept unbuffered non-ECC DIMMs.

Perguntas sobre este artigo

What DDR4 standard and speed does this 32GB RDIMM use, and what throughput ceiling does that impose?

It runs at DDR4 2133 (PC4-17000) with CL15 latency, capping peak bandwidth at 17 GB/s per module.

What physical slot and form factor are required to install this 288-pin ECC registered DIMM?

A standard 288-pin DDR4 DIMM slot on a compatible Supermicro X10-series motherboard; no heat spreader means low-profile clearance.

How is this registered ECC module installed, and what common mistake should be avoided?

Align the notch, press firmly until the retention clips click, and do not mix it with unbuffered memory or install in a desktop board.
