Workstation DDR5 ECC module

The HP 340K1AA is a 16GB DDR5 registered DIMM built for workstation platforms that require error-correcting memory. It delivers 4800 MHz speed with a PC5 38400 data rate in a single 288-pin module. This part targets professionals who need data integrity for compute-intensive tasks.

Registered DDR5 platform constraints

Registered DDR5 memory operates only on motherboards designed for registered DIMMs and the DDR5 standard; it will not fit or function in consumer boards wired for unbuffered modules. The 4800 MHz JEDEC rate is the baseline, so systems without XMP 3.0 support will run at this speed without manual tuning. Buyers who need higher frequencies or consumer-platform compatibility should look elsewhere.

ECC registered signal processing

The defining specification is the registered ECC design, which adds a register between the DRAM and the memory controller to stabilise heavy loads and corrects single-bit errors in flight. If your workstation motherboard requires registered ECC DIMMs, this module meets that requirement; if it calls for unbuffered non-ECC memory, this is not the correct part.

Perguntas sobre este artigo

Should I choose the single 16GB module or look for a kit?

This is a single 16GB DIMM. Add a second identical module later to enable dual-channel bandwidth on your workstation.

What does the 4800 MHz rating deliver in a real system?

The module runs at 4800 MHz DDR5-4800 (PC5-38400). Actual throughput depends on your CPU and motherboard memory controller.

How does the 288-pin DDR5 interface and registered design affect compatibility?

It fits standard 288-pin DDR5 DIMM slots. Registered signal processing and ECC require a workstation-class platform that supports both features.
