System-Specific DDR3 ECC Registered Module

The Axiom 672631-S21-AX is a 16GB DDR3 1600 ECC Registered DIMM built for HP ProLiant Gen8 servers and workstations. It targets administrators upgrading memory in supported rack, blade, tower or scalable platforms that require registered error-correcting modules.

240-Pin DIMM Fits Gen8 Memory Slots

The module uses the standard 240-pin DDR3 form factor and installs directly into compatible HP Gen8 memory slots without adapters. Registered signal processing reduces electrical load on the memory controller, freeing headroom for larger total capacities across populated channels.

Low-Voltage DDR3 Operation Runs Cool

DDR3 1600 (PC3 12800) at 1.35 V typical voltage keeps power draw modest during sustained workloads. ECC correction handles single-bit errors silently while registered buffering steadies signal integrity, helping maintain stable thermals in densely populated chassis.
