The HP 809209-B21 is a genuine 128GB DDR4 server memory module. It runs at 2400MHz on the PC4-19200 standard. It uses ECC Load Reduced design. The layout is octal-rank. It uses a 288-pin form factor at 1.2V.
Octal-rank LRDIMM packs eight ranks onto one module. It uses a data buffer chip. This was one of the earliest ways to reach 128GB per DDR4 module. Newer 3DS die-stacking came later. The module carries a CL17 latency rating.
This module fits HP ProLiant Gen9 servers built for high-density DDR4-2400 memory. Many DL380 Gen9 and DL560 Gen9 models support octal-rank LRDIMM. Always check your exact model's memory list first. Octal-rank support varies by platform.
This module is refurbished, not new. Each one is cleaned and tested. This confirms it works before it gets listed. The chips are HP-qualified, not a generic substitute. A 30-day warranty covers every order.
This module suits a Gen9 server with top density needs on an early DDR4 platform. Large in-memory databases benefit most. It also replaces a failed octal-rank module with a matched, genuine HP part.
Early DDR4 die densities were lower. Reaching 128GB required more ranks. Later generations reached the same capacity with fewer, denser ranks.
No. Check your exact model and CPU generation. 128GB LRDIMM support varies even within the Gen9 family.
