A-Tech 16GB DDR3 1600 ECC RDIMM 2Rx4 for Hynix HMT42GR7AFR4C-PB Server Memory

16GB DDR3 1600 ECC RDIMM for Server Workloads

This registered DIMM delivers 16GB of DDR3 memory at 1600MHz with CL11 latency. It targets administrators upgrading or repairing compatible server and workstation platforms that require ECC error correction and registered signal buffering. The module uses a 2Rx4 organisation and operates at the standard 1.5V DDR3 voltage.

DDR3 1600 Registered Interface Limits

The DDR3 1600 interface caps bandwidth at the PC3-12800 data rate, which restricts throughput compared to newer DDR generations. Registered buffering adds a clock cycle of latency but reduces electrical load on the memory controller, enabling larger total system capacities than unbuffered modules allow. ECC functionality consumes one bit per byte for error detection and correction.

16GB Capacity Headroom and Constraints

A single 16GB module suits workloads such as virtualisation hosts, database buffers and compute nodes that benefit from ECC protection. Capacity runs out when the platform reaches its maximum supported DIMM count or total memory limit, which varies by system and is not defined by the module itself. Systems requiring unbuffered memory or non-ECC operation cannot use this module.
