OWC 32GB DDR4 3200 ECC UDIMM 2Rx8 CL22 1.2V memory upgrade for QNAP TVS-h1288X TVS-h1688X

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.
