Brute Networks 16GB DDR4-2666 ECC Registered RDIMM 2Rx8 1.2V CL15 HP Compatible 868846-001

HP-compatible DDR4 RDIMM

This 16GB DDR4-2666 registered ECC module is built for HP server platforms that require 288-pin RDIMMs. It delivers 16GB of capacity at 1.2V with CL15 latency and a 2Rx8 organisation. The part matches HP part number 868846-001 and uses major-brand DRAM chips. It is suited for administrators expanding memory in compatible HP ProLiant or Apollo systems.

Upgrade from lower-capacity or non-ECC DIMMs

Replacing smaller unbuffered or non-ECC sticks with this registered ECC RDIMM adds error correction and allows higher per-slot density. The jump is worth it when workloads demand data integrity and the server board supports registered memory. Systems limited to unbuffered DIMMs or a different DDR generation cannot use this module.

DDR4-2666 registered ECC constraints

The DDR4 interface tops out at 2666 MT/s on this module, so faster DDR4 speeds are not accessible. Registered buffering adds one clock cycle of latency versus unbuffered DIMMs. ECC function requires a platform that enables the feature in BIOS. Mixing ranks or voltages beyond 1.2V may prevent the server from posting.
