This OWC module delivers 64GB of DDR4 3200 memory with CL22 latency and 1.2V operation. It is a 288-pin ECC Registered DIMM built for the QNAP TS-h1290FX. The 2Rx4 rank configuration supports server workloads that require error correction and registered signalling.

Verify your QNAP TS-h1290FX memory slots

Before ordering, confirm that the TS-h1290FX accepts 288-pin DDR4 ECC Registered RDIMMs and check the maximum capacity per slot. This module cannot be mixed with unbuffered memory. Ensure all installed DIMMs share the same capacity, speed and manufacturer for optimal performance.

Suited for TS-h1290FX owners needing ECC

Ideal for administrators expanding a QNAP TS-h1290FX with registered ECC memory. Not suitable for standard desktop PCs or systems that require unbuffered modules. Buyers who need non-ECC memory or a different form factor should look elsewhere.
