Installing the Memory

The MB838 board supports four DDR3 memory socket for a maximum
total memory of 32GB in DDR3 DIMM memory type.

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 module in an upright position until the clips of

the slot close to hold the DDR3 module in place when the DDR3
module touches the bottom of the slot.

3. To remove the DDR3 module, press the clips with both hands.
