Server-grade ECC RDIMM

This 16GB DDR4 module runs at 2933MHz with CL21 latency and 1.2V operation. It uses a 2Rx4 registered design with full ECC support for data integrity. The 288-pin form factor fits server and workstation memory slots that require registered DIMMs.

Registered DIMM integration

The module requires a platform that supports DDR4 registered ECC memory, such as compatible servers, workstations or NAS systems. It cannot be used in standard desktop boards or mixed with unbuffered DIMMs. Backward compatibility with 2133MHz, 2400MHz and 2666MHz buses allows deployment in older DDR4 platforms.

Low-voltage thermal profile

Operating at 1.2V keeps power draw modest for high-density server configurations. The absence of a heat spreader relies on chassis airflow for cooling, which is typical for registered DIMMs in managed environments. JEDEC compliance ensures stable operation within standard thermal limits.

Preguntas sobre este artículo

What sustained-use limit appears first with the 2Rx4 registered ECC module running at 2933 MHz?

The registered buffer adds one cycle of address latency, so the memory controller hits command-scheduling throughput limits before bandwidth or temperature become bottlenecks.

How much heat and power does the 1.2 V DDR4 RDIMM produce during all-day server loads?

At 1.2 V with no heat spreader the module runs cool; typical registered DDR4 at this voltage draws only a few watts per stick and stays well within standard server airflow limits.

What must the system already provide for this 288-pin ECC RDIMM to function?

A server or workstation motherboard with DDR4 RDIMM slots, a memory controller that supports ECC registered operation, and a CPU/chipset qualified for 2933 MT/s (or 2133/2400/2666 MT/s fallback).
