Server-Specific 32GB DDR4 Module

This single 32GB DDR4 2400 CL17 2Rx4 VLP ECC Registered DIMM is built for the Supermicro SuperBlade 7428R-T3N and listed compatible blades. It operates at 1.2V on a 288-pin interface and is validated for server and workstation workloads that require error-correcting registered memory.

Very-Low-Profile Registered Build

The very-low-profile form factor fits dense blade chassis where vertical clearance is limited. Registered buffering and ECC protect data integrity in multi-module configurations, while the 2Rx4 organisation supports high-capacity population. No heat spreader is fitted, relying on chassis airflow. Mixing with unbuffered or load-reduced modules is not supported.

Replaces Supermicro MEM-DR432LC Series

This module directly replaces Supermicro part numbers including MEM-DR432LC-ER24, MEMDR432LCL01ER24 and related variants. The upgrade is justified when expanding capacity in a supported SuperBlade or when replacing failed sticks with a JEDEC-compliant, RoHS-compliant alternative. It will not work in standard desktop systems.

Questions about this item

What DDR4 speed and bandwidth does this 288-pin module deliver?

The module runs at DDR4 2400 (PC4-19200) with CL17 latency, providing 19200 MB/s peak bandwidth at 1.2 V.

Will this VLP RDIMM fit in a standard-height server slot?

Yes, the very-low-profile 288-pin form factor is designed for dense Supermicro SuperBlade systems such as the 7128RG-X and 7428R series where vertical clearance is limited.

What is the correct way to install this registered ECC DIMM so the system recognises all 32 GB?

Populate one module per channel in identical banks, ensure the notch aligns with the 288-pin key, and do not mix with unbuffered or load-reduced DIMMs.
