HP-Compatible 8GB DDR4-2133 ECC UDIMM

This module is an 8 GB DDR4-2133 ECC UDIMM built to match HP part number 819880-S21. It targets administrators upgrading or repairing HP servers that require unregistered ECC memory. The 1Rx8 organisation and 1.2 V operation follow the PC4-17000 specification for mainstream server platforms.

DDR4-2133 speed and CL15 latency set the bandwidth

The PC4-17000 rating limits peak transfer rate to 17 000 MT/s, so workloads that scale with memory throughput will hit this ceiling. CL15 timing adds a fixed access delay that cannot be tightened without modules rated for lower latency. ECC overhead consumes a small portion of bandwidth for error correction.

Standard 288-pin UDIMM installs like any DDR4 DIMM

Alignment keys prevent backward insertion, and the unregistered design needs no extra configuration in most HP BIOS versions. Mismatched ranks or mixing registered and unregistered DIMMs are the usual causes of boot failure or reduced channel performance. Populating identical modules per channel avoids these issues.

Questions about this item

Is the 8 GB DDR4-2133 CL15 module the only capacity and speed offered for this HP-compatible part?

The listed module is an 8 GB DDR4-2133 CL15 ECC UDIMM with a 1Rx8 organisation and 1.2 V operation. Other capacities or speeds would carry different part numbers.

What does the PC4-17000 rating mean for actual throughput in a server?

PC4-17000 indicates a peak transfer rate of 17 000 MB/s at 2133 MT/s; real-world bandwidth depends on the memory controller, channel population and workload.

Will this 288-pin DDR4 ECC UDIMM work in a system that requires registered memory?

No, the module is unregistered (UDIMM) and 1Rx8; it only fits platforms that accept unbuffered ECC DDR4 at 1.2 V.
