INSTALLATIONS
Installing the Memory
The MI805 board supports two DDR3-1333 memory slots.
Remarks:
J1900 supports two SO-DIMM (w/o ECC) modules. Total maximum
memory supported is 8GB.
Installing and Removing Memory Modules
To install the DDR3 modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR3 module so that the key of the DDR3 module aligned
with that on the memory slot.
2. Gently push the DDR3 m odule in an upright position until the clips of
the slot close to hold the DDR3 module in place when the DDR3
