Replacing Memory Modules
The TS-hx83XU-RP 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 all four slots at the
same time.
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.
Ensure the following when replacing memory modules:
• When installing one memory module, install the memory in slot 1.
• When replacing two memory modules, ensure that each pair uses identical modules.
• When replacing four memory modules, ensure that all four modules are identical.
• Install the pairs in sequence and follow the assigned slots for each pair.
• When installing four memory modules, install the memory in slots 2, 4, 1, and 3.
