32GB DDR4 ECC UDIMM for QNAP NAS

This 32GB DDR4 3200 ECC unbuffered module is built for QNAP TVS-h1288X and TVS-h1688X systems. It targets administrators who need error-correcting memory to protect data integrity in always-on storage appliances. The single DIMM delivers 32GB capacity with CL22 latency at 1.2V.

288-pin DDR4 slot compatibility

The module fits a standard 288-pin DDR4 UDIMM slot and operates at PC4-25600 speed. It runs unbuffered, so the platform must support unbuffered ECC DIMMs. Backward compatibility with 2133, 2400, 2666 and 2933MHz buses lets it drop into slower memory channels without configuration changes. No heat spreader is included, leaving clearance for tight chassis layouts.

32GB single-module capacity headroom

One 32GB rank-2Rx8 DIMM expands usable memory for virtual machines, container workloads and large-volume file services. Systems with multiple slots can scale further by adding identical modules. The limit is the platform's maximum supported memory per channel and total socket count, which this module does not define.

Questions about this item

Will the 32GB DDR4 3200 ECC UDIMM run at its rated 3200MHz speed continuously in a QNAP TVS-h1288X?

The module is rated for DDR4 3200 (PC4-25600) with CL22 latency and 1.2V operation. It will run at that speed provided the NAS memory controller supports 3200MHz ECC unbuffered DIMMs.

How much heat does the 32GB DDR4 3200 ECC UDIMM generate during 24/7 NAS operation?

The module operates at 1.2V without a heat spreader. Typical DDR4 ECC UDIMMs at this voltage run cool enough for continuous NAS use with standard chassis airflow.

Does the QNAP TVS-h1688X need any specific BIOS setting or firmware version to recognise this 32GB DDR4 3200 ECC UDIMM?

The module is a direct replacement for QNAP part numbers RAM-32GDR4ECK0-UD-3200 and RAM-32GDR4ECT0-UD-3200 and is designed to meet OEM specifications for the TVS-h1288X and TVS-h1688X.
