A-Tech 4GB DDR3 1333 PC3-10600 ECC RDIMM 1Rx4 Server RAM

4GB DDR3 1333 ECC RDIMM for servers

This 4GB DDR3 1333 module is an ECC registered DIMM built for server and workstation systems that require error-correcting memory. It replaces Hynix HMT351R7AFR4C-H9 and equivalent part numbers in compatible platforms. The single-rank 1Rx4 design uses major-brand chips at standard 1.5V. Buyers needing higher-density modules or non-ECC memory for consumer boards should look elsewhere.

Capacity and headroom

The module provides 4GB of DDR3 1333 (PC3-10600) capacity with CL9 latency. It handles typical server workloads such as virtualisation hosts, database buffers and multi-user application servers within this limit. Memory-intensive tasks like large in-memory analytics or heavy container fleets will exceed the 4GB ceiling and require additional DIMMs or higher-capacity sticks.

Thermals, noise and power

Operating at the standard DDR3 voltage of 1.5V, the registered DIMM draws modest power and runs passively without a fan. In normal server chassis airflow the module stays cool and adds no audible noise. Power draw scales with bus activity but remains low compared to CPU and storage subsystems.
