32GB DDR4-2933 ECC Registered DIMM

This module delivers 32GB of DDR4-2933 memory with CL21 latency in a registered dual-rank design. The onboard register reduces electrical load on the memory controller, allowing stable operation when multiple modules are populated. It targets workstations and servers that require error-correcting code protection for data integrity.

Registered dual-rank layout for dense configurations

The registered architecture buffers address and command signals, which lowers the per-module load on the memory bus and helps maintain signal integrity at higher population counts. Dual-rank organisation increases density per slot, so fewer modules are needed to reach large system capacities. Standard 288-pin DIMM form factor fits desktop and server boards that support registered ECC memory.

ECC protection and Samsung semiconductor quality

On-die error-correcting code detects and corrects single-bit errors, reducing the risk of silent data corruption in critical workloads. Samsung’s DDR4 process delivers doubled bandwidth with reduced voltage compared with earlier generations, improving performance per watt. Enhanced RAS features further strengthen reliability and signal integrity for continuous operation.

Questions about this item

Does DDR4-2933 CL21 actually run at 2933 MT/s on a typical desktop board?

The module is rated for DDR4-2933 at CL21; the memory controller must support that speed and the registered design, otherwise it will down-clock to the highest JEDEC speed the platform allows.

Will a 32 GB registered DIMM fit in a standard desktop DIMM slot?

It uses the standard DDR4 288-pin RDIMM form factor, so it physically fits any desktop DDR4 slot, but the motherboard must support registered ECC memory or the module will not be recognised.

How do I install this ECC registered stick and what step do people miss?

Power off, open the retention clips, align the notch with the key, press firmly until both clips click, then enable ECC and registered mode in BIOS — skipping the BIOS step is the common mistake.
