  • Unbuffered 240-pin UDIMM fits listed QNAP SS-EC and TS-EC models

QNAP NAS 8GB DDR3 ECC module

This 8GB DDR3 1600 CL11 ECC UDIMM is built for QNAP SS-EC and TS-EC series SAS storage appliances. It replaces QNAP part numbers RAM-8GDR3EC-LD-1600 and RAM-8GDR3-LD-1600 with a single 2Rx8 240-pin module. The unbuffered design suits systems that require ECC without registered signalling.

DDR3 1600 PC3-12800 interface limits

The DDR3 1600 standard caps transfer rate at 12800 MB/s and operates at 1.5V JEDEC voltage. Unbuffered ECC modules rely on the memory controller for error correction without adding register latency. Systems that demand registered or load-reduced DIMMs will not accept this module.

8GB single-module capacity decides fit

One 8GB stick upgrades a single slot; total system memory depends on how many slots the NAS provides and the maximum per slot the firmware allows. Buyers needing larger per-module density or non-ECC memory for desktop boards should look elsewhere.

Questions about this item

Should I pick the 8GB DDR3 1600 CL11 ECC UDIMM or a different capacity for my QNAP NAS?

This module is a single 8GB stick. Add one per empty slot to reach the total memory your QNAP model supports.

What does the 1600MHz speed rating mean once the module is installed in a QNAP SS-EC1279U-SAS-RP?

The module runs at DDR3 1600 (PC3-12800) with CL11 latency, delivering the rated throughput the NAS memory controller expects.

Does the 240-pin DDR3 ECC unbuffered interface limit performance in a QNAP TS-EC1279U-SAS-RP?

The 240-pin DDR3 ECC unbuffered design matches the QNAP specification, so the memory controller operates at its native DDR3 1600 rate.
