Replacing Memory Modules
The NAS has four memory slots. You can increase the memory capacity of the NAS by upgrading the
memory module.
Use only QNAP modules of the same type and capacity to maintain system performance and stability. You
can purchase QNAP memory modules from authorized resellers.
Important
QNAP recommends installing modules in pairs.
• Ensure that each pair uses identical modules.
• Install the pairs in sequence and follow the assigned slots for each pair.
• Install memory modules in groups of two or four. When installing two memory modules,
install the memory in slots 1 and 3. When installing four modules, install the memory in
slots 1, 3, 2, and 4.
For details on slot numbering, see System Board.
