Hynix HMT42GR7BFR4A-PB 16GB DDR3-1600 ECC REG accessory

Hynix 16GB DDR3-1600 ECC Registered Memory

This module provides 16 GB of DDR3 memory operating at 1600 MT/s with error-correcting code and registered signalling. It is intended for servers and workstations that require data integrity and signal stability under continuous operation. The component is not compatible with standard consumer desktop or laptop platforms. Buyers should verify that their system specifically supports registered ECC DDR3 memory before purchasing.

Sustained operation with error correction

The registered buffer reduces electrical load on the memory controller, helping maintain consistent timing during prolonged workloads. ECC circuitry detects and corrects single-bit errors, preventing silent data corruption that can accumulate over long compute sessions. This combination suits environments such as virtualisation hosts, database servers and scientific computing nodes where uptime and accuracy are critical. Performance scales with the number of populated channels and the memory controller capabilities of the host platform.

Verify platform support for registered ECC DDR3

Confirm that the motherboard or server chassis accepts registered DDR3 DIMMs and that the CPU memory controller enables ECC functionality. Consumer chipsets typically disable both features, so the module will not post or will operate in a reduced mode. Check the vendor qualified-vendor list and the system manual for supported ranks, voltages and population rules. Ensure the operating system and firmware are configured to report corrected errors for full benefit.
