Replacing Memory Modules
Each storage controller has eight 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
For best results, 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.
• The ES1686dc has eight memory slots. For optimal quad-channel performance, install
memory modules on either four or eight of the slots. When installing four memory
modules, install the memory in slots 1, 3, 6, and 8.
For details on slot numbering, see System Board.
