Memory bars are main board components that you can expand or upgrade as needed. Generally, you
need to do that in the following situations:
More memory is required when upgrading application program, maintaining a large routing table, or
processing tasks that consume large memory.
The existing Memory bar is damaged.
Hold the memory bar by its edge and avoid touching the components on its surface. An improper
operation might result in damage.
It is normal that you feel hard when removing the memory bar, but do not overexert.
Use the memory bars provided by Technology only. Otherwise, anomalies might occur to the
device.
