DIMM slot provdes a sngle channel. The memory modules can transmt and receve
data wth four data bus channels smultaneously to enhance system performance.
Important
DDR3 memory modules are not nterchangeable wth DDR2, and the DDR3 standard
s not backward compatble. Always nstall DDR3 memory modules n DDR3 DIMM
slots.
To ensure system stablty, memory modules must be of the same type and densty.
Always nsert memory modules n the DIMM1 slot first.
Due to chpset resource usage, the system wll only detect up to 63+ GB of memory
(not full 64 GB) when all DIMM slots have 16GB memory modules nstalled.
