Supermicro Certified 8GB DDR4 ECC RDIMM

This 8GB DDR4 2133MHz module is Supermicro certified and built with Micron chips. It operates at 1.20V with CL15 latency and registered ECC for error correction. The single-rank 1Rx4 design fits 288-pin RDIMM slots in compatible servers and workstations.

Suits ECC registered DDR4 systems needing 8GB

This module is not for non-ECC consumer platforms or boards that require unbuffered UDIMM memory. It will not work in systems limited to lower voltages or different pin counts. Buyers needing higher capacities or faster speeds must select other modules.

Registered ECC with 1Rx4 organisation

The registered buffer and ECC function require a motherboard chipset that supports both features. Single-rank 1Rx4 layout affects maximum population rules on some server boards. Verify your platform accepts registered ECC RDIMMs before purchase.

Questions about this item

Does the 8GB DDR4 2133MHz ECC RDIMM arrive as a single stick or a kit?

The listing shows one 8GB module (1 x 8GB) so you receive a single registered DIMM; add more sticks to reach your desired total capacity.

Should I pick the 1Rx4 CL15 1.2V version or a different rank/voltage?

This module is 1Rx4, CL15 at 1.2V — match those exact specs to your motherboard's qualified-vendor list; mixing ranks or voltages can prevent the server from posting.

What does the PC4-17000 rating mean for actual throughput in my server?

PC4-17000 equals 17 GB/s peak bandwidth per module at 2133 MT/s; real-world throughput depends on channel count, CPU memory controller and workload.
