8GB DDR4-2133 ECC UDIMM with CL15 latency and 1.2V operation for HP-compatible servers
This 8 GB DDR4-2133 module carries ECC protection and a CL15 latency at 1.2 V. It targets administrators who need to expand memory in compatible HP systems without changing the existing memory configuration. The unbuffered design keeps installation straightforward for qualified platforms.
The stick uses the standard 288-pin DDR4 form factor and operates at the PC4-17000 data rate. It requires a motherboard that accepts unregistered ECC UDIMMs at 1.2 V and can run at 2133 MT/s. Systems needing registered or load-reduced modules cannot use this part.
Modules are built with Samsung, SK Hynix or Micron components and are 100 % tested for HP compatibility. The supplier provides a lifetime warranty and a 60-day no-questions-asked return window. Orders are filled with identically matched sticks to avoid mixing different ICs.

CL15 means the column-access delay is fifteen cycles at 2133 MT/s, which determines the minimum timing for each random read during continuous workloads.
The module operates at 1.20 V DDR4 standard voltage; sustained power and heat depend on the platform's memory controller and airflow, not on the DIMM alone.
This part is validated as equivalent to HP 803660-091 for HP platforms that take unregistered DDR4-2133 ECC UDIMMs; verify your model's memory list before installing.
