Replacing Memory Modules - Samsung TS-1655 User Manual

Replacing memory modules

The NAS has four memory slots. You can increase the memory capacity of the NAS by upgrading memory
modules. For optimal dual-channel performance, replace memory modules in pairs.
This NAS also comes preinstalled with one non-ECC memory module. To provide extra protection from
undetected data corruption, you can upgrade to ECC memory modules.
Use only QNAP memory modules to maintain system performance and stability. You can purchase QNAP
memory modules from authorized resellers.
Important
• QNAP recommends installing modules in pairs to run dual-channel mode.
• Ensure that each pair uses identical modules.
Ensure that each memory channel uses identical modules. See table below for
details:
