8GB DDR4 2933 ECC RDIMM for servers

This 8GB DDR4 module runs at 2933 MHz with CL21 latency and 1.20V operation. It uses a registered DIMM design with ECC for error correction in server and workstation platforms. The single-rank 1Rx8 layout fits 288-pin DDR4 slots. It replaces the Samsung M393A1K43DB1-CVF part number.

Sustained load stability

Registered buffering reduces electrical load on the memory controller during continuous operation. ECC detects and corrects single-bit errors that can accumulate under long-running workloads. Standard 1.20V DDR4 voltage keeps power draw predictable across extended sessions. Quality testing validates reliability before shipment.

Registered ECC requirement

This module only works in systems that support registered ECC DDR4 memory. Consumer desktop boards without registered ECC support cannot use it. Verify your platform documentation for registered ECC compatibility before purchase.

Questions about this item

How much heat and power does the 1.20V DDR4 2933MHz ECC RDIMM draw when running continuously in a server?

The module operates at the standard DDR4 voltage of 1.20V, keeping power draw and heat output low during sustained workloads.

What motherboard slot and memory controller features are required to use this 288-pin ECC RDIMM?

You need a server or workstation board with a 288-pin DDR4 DIMM slot and a memory controller that supports registered ECC modules.

Will this CL21 1Rx8 registered module work alongside older DDR4 ECC RDIMMs of different speeds or ranks?

It will run at the lowest common speed and timings; mixing ranks is supported but population rules depend on your specific platform.
