Server Memory for Enterprise Workloads

This 32GB DDR4 RDIMM is built for servers and workstations that require error-correcting, registered memory. It suits administrators upgrading Supermicro platforms or similar enterprise systems needing dependable capacity for virtualization, databases, or compute tasks.

Registered ECC with 2Rx4 Organisation

The module operates at DDR4 2133 (PC4-17000) with a CAS latency of 15 and a 2Rx4 dual-rank layout. Registered buffering and ECC protect data integrity, making this the decisive spec for platforms that mandate registered DIMMs and will not accept unbuffered or non-ECC alternatives.

Standard Voltage and Thermals

Rated at 1.2V, the DIMM runs at the standard DDR4 voltage without elevated power draw. Passive cooling via system airflow is sufficient in normal server chassis, keeping thermals and acoustic impact negligible under typical workloads.

Questions about this item

How does 2133 MHz DDR4 speed affect real-world server performance?

The 2133 MHz clock delivers PC4-17000 bandwidth, which is the baseline DDR4 rate; actual throughput depends on your platform's memory controller and channel population.

What does ECC Registered RDIMM mean for system compatibility?

ECC Registered RDIMM modules include a register that buffers address and command signals, allowing higher capacities per channel, but they require a motherboard and CPU that support registered ECC memory.

Will this 288-pin RDIMM fit in my server's memory slots?

The module uses the standard 288-pin DDR4 RDIMM form factor; it fits any server board with DDR4 RDIMM slots that accept 2Rx4 registered DIMMs.
