4GB DDR3 upgrade for QNAP NAS

This 4GB DDR3 1600 CL11 UDIMM is built for the QNAP TS-879U-RP, TS-1279U-RP and TS-1679U-RP. It replaces the original QNAP part RAM-4GDR3-LD-1600 and adds a single unbuffered non-ECC module to compatible rackmount systems.

Tool-free DIMM installation with one caveat

The 240-pin module seats in the standard desktop DIMM slot and requires no special tools. The main issue is mixing ranks: this stick is 2Rx8, so adding it alongside 1Rx8 modules can prevent the NAS from posting. Match the existing rank configuration or populate all slots with identical modules.

Verify model, slot count and maximum memory

Confirm the exact NAS model number on the chassis label before ordering. Check how many DIMM slots your unit has and the maximum supported capacity per slot in the QNAP hardware guide. This module is not compatible with other QNAP series or standard desktop motherboards.
