Capacity and compatibility

This single module provides 128GB of DDR4 ECC registered memory built for the QNAP TS-h1290FX. It uses a 288-pin form factor and operates at 1.2V with a CL22 latency rating. The 4Rx4 organisation suits high-density server configurations. Workstations and standard desktops cannot use this registered design.

Sustained operation

ECC circuitry detects and corrects single-bit errors during continuous workloads, preserving data integrity over long uptimes. Registered buffering reduces electrical load on the memory controller when all slots are populated. JEDEC-standard 3200 MT/s signalling maintains stable throughput without relying on short-term boost behaviour. The module runs at the rated voltage without additional cooling requirements.

Deciding specification

The registered ECC design is the determining factor; it will not function in systems that require unbuffered non-ECC memory. Buyers whose platforms demand standard desktop DIMMs must select a different module type. Mixing this module with unbuffered memory is not supported and will prevent boot. Compatibility is confirmed only for the listed QNAP model.

Questions about this item

How much power does the 1.2V ECC registered DIMM draw when the QNAP TS-h1290FX runs continuously?

The module operates at 1.2V, the standard DDR4 voltage for registered ECC DIMMs, keeping power draw low during all-day workloads on the TS-h1290FX.

What must the QNAP TS-h1290FX already support for this 288-pin 4Rx4 module to function?

The NAS must accept DDR4 3200 registered ECC memory with a 4Rx4 organisation; the TS-h1290FX is the validated platform for this 128GB DIMM.

Can I add this 128GB stick alongside the original memory already in my TS-h1290FX?

OWC recommends matching capacity, speed and manufacturer; mixing this 128GB CL22 module with different existing DIMMs may prevent optimal performance.
