Replacing Memory Modules
The TS-hX86 series has four memory slots. You can increase the memory capacity of the NAS by upgrading
memory modules. For optimal quad-channel performance, replace memory modules in all four slots at the
same time.
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 all four modules are identical.
• Install the pairs in sequence and follow the assigned slots for each pair.
•
For details on slot numbering, see Right Panel.
Module Pair Slot Number
First pair Slots 1 and 3
