8 GB DDR4 ECC UDIMM for QNAP NAS

This 8 GB DDR4 3200 module adds error-correcting memory to compatible QNAP TVS-h1288X and TVS-h1688X systems. It runs at PC4-25600 with CL22 latency and 1.2 V operation. The unbuffered 1Rx8 design fits standard 288-pin UDIMM slots. Builders expanding a supported NAS can install it directly.

JEDEC standard compliant upgrade

The module meets JEDEC and RoHS specifications, so it installs without voiding the original system warranty. Backward compatibility lets it clock down to 2133, 2400, 2666 or 2933 MT/s if the platform requires a lower speed. No extra software or drivers are needed; the NAS recognises the memory on boot.

ECC unbuffered 288-pin DDR4 3200

The decisive specification is the ECC unbuffered DDR4 3200 interface in a 288-pin UDIMM form factor. Only systems that accept this exact combination will operate correctly. Buyers whose hardware requires registered, non-ECC or a different DDR generation cannot use this module.

Preguntas sobre este artículo

Will the single 8 GB DDR4 3200 CL22 ECC UDIMM need replacement if I expand my QNAP TVS-h1288X beyond its current capacity?

The module is a single 8 GB stick; adding more memory later simply means populating empty slots, not replacing this one.

What speed ceiling appears first when the module runs continuously in a TVS-h1688X?

The JEDEC-rated 3200 MT/s CL22 is the fixed operating point; the module does not throttle below that speed under sustained load.

How much heat and power does the 1.2 V unbuffered DIMM produce during all-day NAS operation?

At 1.2 V with no heat spreader, the stick draws standard DDR4 power and relies on chassis airflow for cooling.
