Supermicro-Certified DDR4 ECC RDIMM

This module is a 32GB DDR4 3200MHz ECC Registered DIMM validated for Supermicro platforms. It uses Micron chips in a 2Rx4 dual-rank layout at 1.20V with CL22 latency. The 288-pin form factor fits standard server DIMM slots.

Suited for servers needing registered ECC memory

Systems that require unbuffered UDIMMs, non-ECC modules or speeds above 3200MHz cannot use this stick. Workstations limited to lower voltage or different pin counts should look elsewhere.

Single 32GB module provides substantial capacity

Dual-rank organisation helps density on boards with limited slots. Very large memory arrays may hit rank-per-channel limits before filling every socket. Maximum supported capacity depends on the platform specification.

Questions about this item

Does my motherboard need to support ECC Registered DDR4 RDIMMs for this 32GB module to work?

Yes, the module is a 288-pin DDR4 3200 ECC Registered RDIMM running at 1.20V with CL22 latency, so the platform must accept registered ECC memory in that form factor and speed.

How does this 3200 MHz CL22 module behave when installed alongside slower DDR4 ECC RDIMMs?

The memory controller will run all populated channels at the lowest common speed and highest latency; this module will down-clock to match the slower sticks while keeping its 2Rx4 organisation and 1.20V operation.

How can I verify the module is running at 3200 MHz with ECC active after installation?

Check the BIOS memory information or use a tool such as dmidecode to confirm 3200 MT/s, CL22 timings, registered ECC type and 1.20V; the Supermicro certification label MEM-DR432L-CL03-ER32 should also be visible on the module sticker.
