Certified Supermicro DDR4 RDIMM

This 32 GB DDR4 2666 MHz ECC registered DIMM carries Supermicro certification and uses Samsung chips. It targets administrators upgrading or repairing Supermicro servers that require registered error-correcting memory. The single module delivers 32 GB capacity at 1.2 V with CL19 latency.

288-pin RDIMM installs in standard DDR4 server slots

The module fits any 288-pin DDR4 RDIMM slot keyed for registered memory. Alignment notches prevent incorrect insertion, and the registered buffer reduces electrical load on the memory controller. Common issues arise when mixing registered and unbuffered DIMMs or when the platform does not support ECC, so verify the system specification before installation.

Suited for Supermicro platforms needing registered

This module suits IT teams expanding memory in qualified Supermicro systems that mandate DDR4 2666 registered ECC. It is not for workstations or desktops that accept only unbuffered non-ECC UDIMMs, nor for platforms requiring higher speeds, different voltages, or larger per-module capacities than 32 GB.

Questions about this item

How can I confirm the module is running at 2666 MHz with CL19 timing after installation?

Enter the system BIOS or use a hardware-monitoring utility to verify the memory frequency shows 2666 MHz and the CAS latency reads 19.

What comes in the package and do I need anything else to install it?

The box contains one 32 GB DDR4 2666 MHz ECC Registered DIMM; no extra parts are required — just an available 288-pin RDIMM slot on a compatible server motherboard.

Which capacity or version should I choose for my Supermicro server?

This listing is the single 32 GB 2Rx4 module certified as Supermicro MEM-DR432LC-ER26; select it when your board supports 32 GB per slot and you need registered ECC memory.
