Important
• Use only QNAP memory modules to maintain
system performance and stability. For NAS devices
with more than one memory slot, use QNAP
modules with identical specifications.
• Using unsupported modules may degrade
performance, cause errors, or prevent the
operating system from starting.
• You can only use one type of dual in-line memory
module (DIMM) at a time. Do not use registered
DIMM (RDIMM) with load-reduction DIMM
(LRDIMM) memory.
