Z90DE7 Expansion to 32GB

Z90DE7 Expansion to 32GB

There seems to be no information as to how to expand this unit to the 32GB maximum. I could not find any expansion part numbers or instructions.

Any help or insight would be appreciated, I just ordered 4 of these units in 4GB/2GB configuration with wireless. I will need to upgrade them in capacity to run the WES7P (image is almost 7G).

Thanks in advance,
