16GB DDR4 2400 Module for QNAP NAS

This 16GB DDR4 2400 UDIMM is built for QNAP TS-873U, TS-873U-RP and TS-877 systems. It replaces OEM part numbers RAM-16GDR4A0-UD-2400 and RAM-16GDR4A1-UD-2400. The module targets administrators expanding memory in these specific NAS units.

DDR4 2400 CL17 Standard Limits

The module runs at 2400MHz with CL17 latency and 1.2V voltage per JEDEC PC4-19200 specification. It is backward compatible with 2133MHz operation. The 288-pin unbuffered non-ECC design fits standard DDR4 desktop and workstation slots.

16GB Single-DIMM Capacity Headroom

A single 16GB stick adds substantial headroom for multitasking, larger file caches and concurrent virtual machines. The 2Rx8 organisation populates one slot efficiently. Builders needing more than 16GB per slot or requiring ECC error correction must choose a different module.

Perguntas sobre este artigo

Should I pick the 16 GB module or look for a different capacity?

This part is a single 16 GB stick; choose it when your QNAP TS-873U, TS-873U-RP or TS-877 needs one 16 GB DDR4 2400 module to fill a free slot.

What does the 2400 MHz rating deliver once the stick is installed?

The module runs at 2400 MHz with CL17 timing, giving the NAS its rated DDR4 2400 bandwidth for snappier multitasking and larger file handling.

Is the 288-pin DDR4 interface limited to 2400 MHz or can it run slower?

The 288-pin DDR4 UDIMM is JEDEC-standard at 2400 MHz and will also operate at 2133 MHz if the system requires a lower speed.
