8GB DDR4 ECC RDIMM for Supermicro servers

This 8GB DDR4 2133MHz ECC registered DIMM carries Supermicro certification and uses Micron chips in a 2Rx8 dual-rank layout. It is built for servers and workstations that require error-correcting registered memory running at the standard 1.20V DDR4 voltage. The module fits 288-pin RDIMM slots and operates at CL15 latency.

Steady throughput under sustained server workloads

Registered buffering and ECC circuitry keep data integrity intact during continuous operation, preventing the silent corruption that can accumulate in long-running compute or virtualisation tasks. The dual-rank 2Rx8 organisation allows the memory controller to interleave accesses across two ranks, maintaining consistent bandwidth when all channels are populated. Standard 1.20V operation avoids the thermal spikes that higher-voltage modules can produce under load.

Straightforward installation

The 288-pin RDIMM form factor seats in any DDR4 registered DIMM slot, but the system must support ECC registered memory and the specific Supermicro qualified-vendor list entry for this part number. Mixing registered and unbuffered DIMMs, or populating slots in an unsupported sequence, will prevent the server from posting. Verify the platform's qualified memory list before installing.

Questions about this item

How much heat does the 1.20 V DDR4 2133 MHz module generate under continuous server loads?

The module runs at standard 1.20 V DDR4 voltage, so heat output is typical for an 8 GB registered DIMM; ensure your chassis provides adequate airflow over the memory slots.

What must the motherboard provide to use this 288-pin RDIMM with ECC and registered buffering?

A DDR4 RDIMM slot that supports ECC registered memory and a CPU or chipset with an integrated memory controller capable of 2133 MHz operation.

Will this 2Rx8 CL15 stick work in a system that currently uses 1Rx4 CL17 DDR4 2133 modules?

Mixing ranks and latencies is possible if the platform's memory controller supports mixed configurations; the system will run all modules at the lowest common speed and latency.
