Server memory upgrade

This A-Tech module adds 4GB of DDR3 1600MHz ECC registered memory to compatible servers and workstations. It replaces the Kingston KVR16R11D8/4 part and targets administrators who need dependable capacity for virtualization or database workloads.

Registered DIMM build

The 240-pin RDIMM uses major-brand chips and a 2Rx8 organisation to maintain signal integrity on multi-module channels. Registered buffering reduces electrical load on the memory controller, while ECC detects and corrects single-bit errors during continuous operation.

Verified compatibility

Each unit undergoes quality-assurance testing before shipment to confirm reliable performance in qualified systems. A-Tech backs the module with a lifetime warranty and provides US-based technical support for installation and troubleshooting assistance.
