Server DDR4 module for registered ECC systems

This A-Tech 8GB DDR4 2400 RDIMM is built for servers and workstations that require registered ECC memory. It operates at 2400 MHz with a CAS latency of 17 and runs at the standard 1.2V DDR4 voltage. The dual-rank 2Rx8 organisation uses major-brand chips on a 288-pin DIMM.

Steady throughput under continuous workloads

Registered buffering reduces electrical load on the memory controller, allowing sustained data rates during long compute or virtualisation tasks. ECC corrects single-bit errors on the fly, preventing silent data corruption that can accumulate over hours of operation. The module maintains its rated speed without throttling when installed in compatible multi-channel configurations.

Low-voltage operation keeps thermals modest

At 1.2V the module draws minimal power, contributing little heat inside dense chassis where airflow is limited. Passive cooling via system fans is sufficient; no additional heatsinks or active cooling are required. The registered design also dampens signal noise on the bus, improving stability in fully populated memory channels.

Questions about this item

How much power does this 1.20V DDR4 2400 module draw when the server runs continuously?

The module operates at the standard DDR4 voltage of 1.20V. Actual power draw depends on the server platform and workload; the module itself has no separate power rating.

What must my system already have to accept this 288-pin ECC RDIMM?

Your server or workstation must support DDR4 registered ECC memory in a 288-pin DIMM slot. Desktop and laptop platforms cannot use this module.

Will this CL17 dual-rank module work alongside slower DDR4 registered sticks already installed?

Mixing modules of different speeds or ranks is not recommended. The system will typically run all memory at the lowest common speed and may require specific population rules.
