Server-grade DDR4 ECC RDIMM

This 32GB DDR4 2400MHz registered DIMM delivers error-correcting memory for Supermicro X10 and X11 server boards. It operates at 1.2V with CL17 latency and a 2Rx4 rank structure. The module is built for 288-pin slots in workstation and NAS environments that require registered ECC memory.

Replaces Supermicro MEM-DR432L series

It directly substitutes Supermicro part numbers including MEM-DR432LC-ER24, MEMDR432LCL01ER24 and MEMDR432LSV01ER24. The upgrade is worthwhile when expanding capacity on compatible X10DRU-i+, X10DRW-i, X10DRW-iT, X11SDD-18C-F or X11SDD-8C-F platforms. It will not work in standard desktop systems or alongside unbuffered DIMMs.

Fits 288-pin registered ECC slots

The module requires a server or workstation motherboard that supports DDR4 registered ECC memory at 2400MHz. It frees unbuffered slots for other uses while adding 32GB per DIMM to the registered memory pool. No heat spreader is fitted, so airflow across the DIMM row should be maintained.

Questions about this item

Will this 288-pin DDR4 RDIMM fit the DIMM slots on a Supermicro X11SDD-18C-F motherboard?

Yes, the module is a 288-pin DDR4 ECC Registered RDIMM built for the X11SDD-18C-F and the other listed Supermicro boards.

What is the correct way to seat this registered ECC module, and what step do installers often miss?

Align the notch with the slot key, press straight down until both retention clips click, and verify the board detects the full 32 GB at 2400 MHz in BIOS.

When should this 2Rx4 registered DIMM be replaced in a server running continuous workloads?

Replace it if memtest or the OS logs correctable ECC errors that climb over time, or when a capacity upgrade requires matching 32 GB 2400 MHz registered modules.
