HPE 16GB DDR4-3200 ECC DIMM

This 16 GB single-rank module runs at 3200 MHz with CL22 latency and operates at 1.20 V. It uses unbuffered ECC DDR4 technology on a 288-pin form factor. The part is designed for entry-level HPE server platforms and compatible desktop systems that accept standard UDIMMs.

Sustained operation at 3200 MHz

The single-rank layout helps maintain stable throughput during extended workloads because each rank accesses the full data bus without interleaving delays. ECC circuitry corrects single-bit errors on the fly, preventing data corruption that can accumulate over long compute sessions. The 1.20 V supply voltage keeps thermal output predictable inside dense chassis.

Replaces lower-capacity or non-ECC UDIMMs

Upgrading from 8 GB modules doubles per-slot capacity without requiring registered memory support. The jump is worth it when applications demand error correction and 16 GB per channel, but it does not suit systems that require registered or load-reduced DIMMs. Buyers needing higher densities per slot should look elsewhere.

Questions about this item

How much power does the 1.20 V DDR4 module draw when the server runs continuously?

The module operates at 1.20 V, the standard voltage for DDR4-3200, keeping power draw low during all-day workloads.

What motherboard slot and memory type must my system already have to accept this 288-pin DIMM?

A DDR4 UDIMM slot supporting unbuffered ECC memory at 3200 MHz is required for the 288-pin module to function.

Will this single-rank CL22 stick work alongside older DDR4 modules already installed in my server?

Yes, it will run at the speed of the slowest installed module; matching rank and voltage avoids timing conflicts.
