Replacing Memory Modules
The TS-x77XU 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.
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 the following when replacing memory modules:
• Ensure that each memory channel uses identical modules. See table below for details:
Channel name
Slot numbering
Channel A
Slots 1, 2
Channel B
Slots 3, 4
• When installing one module use the slot furthest from the CPU (slot 4).
• When installing two modules, use slots 2 and 4.
• When installing four modules, use slots 2 and 4 for the first pair, and slots 1 and 3 for
the second pair.
