When expanding AS5 series memory, please ensure that both memory modules you are installing are of the same size.
When purchasing 8GB RAM modules, due to AS5 series platform limitations, you will only be able to install a single 8GB RAM module. The original RAM modules must be removed. It is not possible to have two 8GB RAM modules installed. Please see the graphic.
Installable RAM module combinations are as follows:
1GB + 1GB
2GB + 2GB
4GB + 4GB
Single 1,2,4, 8GB module installed in the first memory slot.
