8GB DDR4 2133 MHz registered ECC RDIMM with CL15 latency and 1.2 V operation for HP servers
This 8GB DDR4 registered DIMM is built for HP servers that require PC4-17000 memory at 2133 MT/s. It uses a 1Rx4 layout, operates at 1.20 V and includes ECC with a CL15 latency. The 288-pin module suits administrators expanding capacity in supported HP platforms.
Registered buffering and ECC keep data integrity stable during continuous workloads such as virtualisation or database serving. The major-brand DRAM chips (Samsung, SK Hynix or Micron) are validated for 100 % compatibility, so error correction and signal quality remain consistent over long periods rather than only in short bursts.
Verify that your HP server accepts DDR4 registered RDIMMs at the PC4-17000 speed grade and that the memory slots support 1Rx4 organisation. Confirm the system BIOS recognises 1.20 V modules and that you are not mixing registered and unbuffered DIMMs in the same channel.

The module operates at 1.20V, the standard low voltage for DDR4, which keeps power draw and heat output modest even in a fully populated server running all day.
The module needs a DDR4 RDIMM slot with registered memory support and ECC capability; it is built to HP 726718-S21 specifications for direct compatibility.
It will run at the lowest common speed and voltage across all populated slots; mixing ranks or speeds is supported by the memory controller but may reduce overall bandwidth.
