16GB DDR5 ECC UDIMM for HP N04487-001

This 16GB DDR5 4800 module is an unbuffered ECC UDIMM built as a compatible replacement for the HP N04487-001 part. It targets server and workstation administrators who need to add error-correcting memory to supported platforms. The single-rank 1Rx8 design operates at the standard 1.10V DDR5 voltage.

288-pin DDR5 4800 CL40 specification

The module runs at DDR5 4800 (PC5-38400) with a CAS latency of CL40. This speed and latency combination is the primary compatibility gate; the system must accept DDR5 4800 unbuffered ECC UDIMMs for the memory to function correctly.

Standard voltage and unbuffered thermals

At 1.10V the module draws the baseline DDR5 power envelope, so thermal output remains typical for a single unbuffered DIMM. No extra cooling is required beyond normal server airflow, and acoustic impact is negligible because the part has no active cooling.

Questions about this item

What does DDR5 4800 (PC5-38400) mean for real-world throughput in a server?

The module runs at 4800 MT/s with a peak transfer rate of 38400 MB/s, delivering that bandwidth when the platform's memory controller operates at the rated DDR5 speed.

How does the unbuffered ECC interface affect error correction and maximum capacity per channel?

Unbuffered ECC provides single-bit correction and multi-bit detection directly on the DIMM without a register, so the memory controller manages timing and the practical limit per channel is set by the board's electrical loading rules.

Will the 288-pin DIMM fit my HP server that lists the N04487-001 part number?

The stick uses the standard DDR5 288-pin DIMM form factor and is built as a compatible replacement for HP N04487-001, so it installs in the same slots as the original module.
