16 GB DDR4 ECC RDIMM for SuperMicro servers

This 16 GB DDR4 2933 MHz ECC registered DIMM is built for SuperMicro server and workstation platforms that require registered memory. It targets IT professionals and system integrators who need validated, single-module capacity upgrades for mission-critical environments.

2Rx8 registered design with 1.20 V operation

The module uses a 2Rx8 organisation and runs at 1.20 V with CL21 latency, conforming to the PC4-23400 standard. Its 288-pin RDIMM form factor fits standard DDR4 registered slots, while the absence of a heat spreader keeps the profile low for dense chassis configurations.

Verify registered DIMM support

Before ordering, confirm that your SuperMicro system accepts DDR4 2933 MHz registered ECC modules and check the motherboard manual for maximum capacity per channel and required population order. Some platforms limit rank count per channel or require specific slot filling sequences.
