Server DDR4 ECC RDIMM 8GB

This registered DIMM delivers 8GB of DDR4 memory at 2933MHz with ECC protection for server and workstation platforms. It operates at the standard 1.2V DDR4 voltage and uses a 1Rx8 organisation on a 288-pin module. The CL21 latency and PC4-23400 rating match the Micron MTA9ASF1G72PZ-2G9 specification it replaces.

Sustained-load behaviour with registered ECC

The registered buffer reduces electrical load on the memory controller, allowing stable operation when all slots are populated under continuous workloads. ECC circuitry detects and corrects single-bit errors in real time, preventing data corruption during long compute runs or virtualisation tasks. Major-brand chips and 1.2V operation keep thermals predictable in dense chassis.

Upgrade path from non-ECC or lower-capacity modules

This module replaces unbuffered non-ECC DIMMs when the platform requires registered memory with error correction. It also supersedes smaller-capacity RDIMMs such as 4GB sticks to increase total system memory without adding slots. The jump is worth it when your workload demands data integrity and the motherboard supports registered DDR4 at 2933MHz.

Questions about this item

Does the 1.20 V DDR4 2933 MHz registered module run hot or noisy under continuous server workloads?

The module operates at standard 1.20 V DDR4 voltage with no active cooling, so it adds negligible heat and produces no audible noise during all-day operation.

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

A DDR4 RDIMM slot with 288 pins and an ECC-capable memory controller that supports registered modules at 2933 MHz is required.

Can this CL21 1Rx8 registered DIMM be mixed with other DDR4 ECC RDIMMs of different speeds or ranks in the same system?

Mixing is possible if all modules are DDR4 ECC RDIMMs; the system will run at the lowest common speed and may require matching rank configurations per channel for stability.
