8GB DDR4 2933MHz ECC RDIMM

This 8GB registered DIMM uses DDR4 technology at 2933MHz with CL21 latency and 1.20V operation. It provides error-correcting code memory for servers and workstations that require registered modules. The single-rank 1Rx8 organisation suits systems qualified for this density. Buyers needing unbuffered UDIMM modules or higher-capacity sticks cannot use this part.

Thermals noise and power draw

Standard DDR4 voltage of 1.20V keeps power draw low during typical server workloads. Passive operation produces no audible noise because the module has no moving parts. Heat output scales with memory utilisation and ambient airflow inside the chassis. Systems without adequate case ventilation may see higher module temperatures under sustained load.

Micron-compatible replacement

The module is built as a compatible replacement for Micron MTA9ASF1G72PZ-2G9E1 using Micron chipset components. Each stick undergoes quality assurance testing before shipment to verify reliable operation. This testing reduces the chance of compatibility surprises during installation. No additional software, drivers or accessories are included in the package.

Questions about this item

How do I install this 288-pin DDR4 RDIMM in my server and what step is often missed?

Align the notch on the 288-pin DDR4 RDIMM with the slot key, press firmly until both ejector clips click shut, then verify in BIOS that the 8GB module registers at 2933MHz with ECC active.

What maintenance or replacement will this 1Rx8 ECC RDIMM need over its service life?

No routine maintenance is required; the module either passes POST and runs error-free or it fails, in which case the entire 8GB stick is replaced under the lifetime warranty.

What is the first limit that appears when this CL21 1.20V DDR4-2933 RDIMM runs sustained heavy workloads?

The CL21 latency at 1.20V sets the throughput ceiling; sustained loads will hit that timing wall before voltage or thermal limits become a factor.
