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.

Questions about this item

Does this 288-pin DDR4 RDIMM fit a standard server DIMM slot?

Yes, the 288-pin DDR4 RDIMM form factor matches standard server DIMM slots designed for registered memory.

What BIOS setting is often missed when installing this registered ECC module?

Enable ECC and registered memory support in the BIOS; the system will not boot correctly if the memory controller expects unbuffered DIMMs.

When should this 16 GB DDR4-2666 module be replaced?

Replace the module if memory diagnostics report correctable ECC errors that increase over time or if the server fails POST with this DIMM installed.
