16GB DDR4-2666 ECC RDIMM

This 16GB DDR4-2666 registered DIMM adds error-correcting capacity to compatible servers and workstations. It runs at 1.2V with a CL15 latency and a 2Rx8 organisation. The module suits administrators who need to expand memory in HP platforms using part number 838089-B21.

Upgrade from lower-capacity DDR4 RDIMMs

Replacing smaller registered modules with this 16GB stick increases the memory ceiling for virtualisation and database workloads. The jump is worth it when current capacity forces swapping or limits the number of concurrent virtual machines. Brute Networks builds each module with major-brand DRAM that meets or exceeds the OEM specification.

Check DDR4 RDIMM slot availability and rank limits

Verify that your system accepts 288-pin DDR4 registered memory and supports 2Rx8 modules at 2666 MT/s. Confirm the maximum rank count per channel and the total module count allowed by the motherboard or processor. Ensure the BIOS is current enough to recognise the 16GB density.

Questions about this item

Will this 288-Pin DDR4 RDIMM fit my server's memory slots?

The module uses the standard 288-Pin DDR4 RDIMM form factor, so it fits any server DIMM slot keyed for DDR4 registered memory.

Is any BIOS setting or voltage adjustment required when installing this 1.20V ECC Registered module?

Install with the server powered off; the 1.20V JEDEC voltage and CL15 timings are detected automatically by the memory controller, so no manual BIOS configuration is needed.

How do I know when a 16GB 2Rx8 stick should be replaced in a production server?

ECC corrects single-bit errors on the fly; replace the module only if the system logs report uncorrectable multi-bit errors or persistent correctable-error thresholds are exceeded.
