SK hynix HMT42GR7BFR4A-PB 16G DDR3 1600 RDIMM
The SK hynix HMT42GR7BFR4A-PB is a 16GB DDR3L registered ECC DIMM running at 1600 MT/s, aimed at buyers maintaining or extending DDR3-generation enterprise servers, data center nodes, and virtualization or database platforms. As a low-voltage (1.35V) RDIMM, it suits fleet-standardized refreshes where consistent voltage and registered signaling matter. Note that DDR3L RDIMMs cannot be mixed with DDR4 or DDR5 modules, so confirm your platform generation before ordering.

Good to know
- As an RDIMM with ECC, this module requires a server-class platform with registered-DIMM support; it will not operate in desktop boards or alongside unbuffered DDR3 memory, and population rules (speed, ranks per channel) are controller-dependent.
- Within the DDR3L RDIMM family, the dual-rank 2Rx4 configuration at PC3L-12800R offers a balanced capacity-per-module profile, typically allowing higher total memory per channel than single-rank modules on supporting platforms.
- Buying tip: verify your server’s qualified memory list (QVL) for 1.35V DDR3L RDIMM support, and where possible populate channels symmetrically with matching modules to maintain rated 1600 MT/s operation.
