Universal 669324-B21 8 GB DDR3 ECC UDIMM 1600 PC3-12800 240-pin

Server-grade ECC UDIMM for HP ProLiant

This 8 GB DDR3 module runs at 1600 PC3-12800 and is certified for HP ProLiant ML310e and BL420c G8 servers. It uses major-brand Micron, Samsung or Hynix chips and is tested in HP hardware before shipment. The unbuffered ECC design protects data integrity in always-on workloads.

240-pin UDIMM installs in standard DDR3 slots

Align the notch with the keyed slot and press firmly until the latches click; no tools or firmware flashes are required. Mixing different chip brands inside one order is avoided by the supplier, preventing timing mismatches that cause boot failures. The single-module layout leaves remaining slots free for future expansion.

Steady throughput under continuous server loads

ECC correction handles single-bit errors without halting the CPU, keeping virtualisation hosts and database nodes stable during extended uptime. Unbuffered topology keeps latency low for memory-bound tasks such as in-memory caches. The 1600 bus speed sustains rated bandwidth across long compute windows rather than short bursts.
