4GB DDR3 ECC UDIMM for QNAP NAS

This single 4GB DDR3 1600 module adds ECC-protected memory to compatible QNAP TS-EC series rackmount NAS units. It installs in a standard 240-pin UDIMM slot and operates at 1.5V with CL11 latency. The unbuffered design suits the supported platforms without requiring registered DIMM support.

Replaces QNAP RAM-4GDR3EC-LD-1600

The module directly replaces the QNAP part number RAM-4GDR3EC-LD-1600 in the TS-EC1279U-RP, TS-EC1679U-RP, TS-EC1679U-SAS-RP and TS-EC879U-RP models. Upgrading is worthwhile when the existing capacity limits concurrent services or virtual machines. It does not suit systems that require registered memory or a different DDR generation.

Sustained operation with JEDEC compliance

Built to JEDEC and RoHS standards, the DIMM maintains stable timing during extended file serving or backup workloads. ECC corrects single-bit errors that can accumulate under continuous load. The lack of a heat spreader means airflow in the chassis must be adequate for passive cooling.

Questions about this item

Will the 240-pin DDR3 UDIMM fit the memory slots in a QNAP TS-EC1279U-RP?

Yes, the 240-pin DDR3 ECC UDIMM matches the slot and form factor required by the TS-EC1279U-RP and the other listed QNAP models.

What is the correct way to seat the module so the ECC UDIMM is fully recognised?

Align the notch with the slot key, press down evenly until both side clips click shut, then verify the full 4GB appears in the NAS firmware.

Does the 1.5V DDR3 1600 module need any firmware update or periodic re-seating to keep ECC working?

No firmware update is required; the JEDEC-standard 1.5V module runs without maintenance, and ECC operates continuously once the system reports the memory as healthy.
