16GB DDR4 2933MHz ECC RDIMM for Servers

This 16GB DDR4 2933MHz ECC Registered RDIMM is built for servers, workstations and NAS systems that require registered memory with error correction. It operates at 1.2V with CL21 latency and a 2Rx8 organisation across 288 pins. The module replaces Hynix parts HMA82GR7CJR8N-WM, HMA82GR7DJR8N-WM and HMA82GR7JJR8N-WM. It is not compatible with standard desktop computers or unbuffered memory configurations.

Replaces slower DDR4 registered modules

The module runs at PC4-23400 2933MHz and is backward compatible with 2133MHz, 2400MHz and 2666MHz server platforms. Upgrading from lower-speed registered ECC DIMMs is worthwhile when the platform supports 2933MHz and the workload benefits from the higher data rate. It will not work in systems that only accept unbuffered or non-ECC memory.

Sustained load behaviour in registered ECC role

Under continuous server workloads the registered buffer and ECC circuitry maintain data integrity while the 1.2V operation keeps power draw consistent. The lack of a heat spreader means airflow across the DIMM slots is required for thermal stability during prolonged operation. JEDEC and RoHS compliance ensures the module meets industry standards for long-term deployment.

Questions sur cet article

What slot and pin count does this 288-pin DDR4 RDIMM require on the motherboard?

It installs in a standard 288-pin DDR4 RDIMM slot on server or workstation boards that support registered ECC memory.

How do I seat the module correctly, and what is the common mistake?

Align the notch with the key in the slot, press straight down until both side clips click; the frequent error is stopping before the clips engage fully.

Will this 16 GB 2Rx8 module need any firmware updates or battery replacements over its service life?

No firmware or battery maintenance is required; the module is a passive component rated for the system lifetime.
