Brute Networks P18444-B21 16GB DDR4 2666 2Rx8 ECC Registered RDIMM

HPE Compatible 16GB DDR4-2666 RDIMM

This 16GB registered DIMM is built to match HPE part number P18444-B21 and runs at DDR4-2666 with a 1.20V operating voltage. It uses a 2Rx8 layout and major-brand DRAM chips from Samsung, SK Hynix or Micron. The module is designed for servers that require ECC registered memory in a 288-pin form factor.

Sustained load behaviour with ECC registered design

The registered buffer reduces electrical load on the memory controller, helping stability when all slots are populated under continuous workloads. ECC corrects single-bit errors on the fly, protecting data integrity during long-running compute or virtualisation tasks. Operation at the standard 1.20V keeps power draw predictable across extended periods.

Verify DDR4 RDIMM support and slot population rules

Confirm that your server platform accepts DDR4 registered DIMMs and check the maximum capacity per channel before ordering. Mixing registered and unbuffered modules is not supported, so all installed DIMMs must share the same registered type. Ensure the memory configuration follows the vendor’s population guidelines for 2Rx8 modules.
