4GB DDR3 ECC UDIMM for QNAP NAS

This single 4GB DDR3 1600 module adds ECC-protected memory to compatible QNAP TS-EC2480U and TS-EC880 series appliances. It targets administrators who need to expand capacity in rack-mount storage servers without registered DIMMs.

Check 240-pin DDR3 slots and maximum capacity

Verify that your NAS has free 240-pin UDIMM slots and that the system firmware accepts unbuffered ECC modules at 1.5V. The QNAP model must appear in the supported list; other DDR3 platforms are not guaranteed to work with this specific part.

Steady ECC operation under continuous workloads

Error-correcting code detects and corrects single-bit errors during long file transfers, backup windows or virtualisation tasks. Unbuffered layout keeps latency low while the JEDEC-standard CL11 timing sustains rated throughput without thermal throttling.

Questions about this item

Does the module arrive as a single stick or do I need to buy anything else to install it?

The package contains one 4GB DDR3 1600 PC3-12800 CL11 2Rx8 240-pin 1.5V ECC unbuffered UDIMM; no extra parts are required for installation.

My QNAP model is listed — is this the only capacity I should use or can I mix sizes?

This module is a 4GB stick validated for the TS-EC2480U, TS-EC2480U-RP, TS-EC880 PRO, TS-EC880U and TS-EC880U-RP; mixing capacities depends on the NAS firmware, so check the QNAP memory guide before combining sizes.

What does the 1600MHz CL11 rating actually deliver inside my TS-EC880U?

The module runs at DDR3 1600 (PC3-12800) with CL11 latency at 1.5V, providing JEDEC-standard bandwidth and error-correction for the NAS workloads the TS-EC880U handles.
