Improving the speed and memory of the connectportx4?

How can I upgrade the speed and memory of the connectportx4 ? Can I swap chips or bolt on hardware?

This is not something supported by Digi. Opening these enclosures will void the product warranty.

If you do not provide a faster processor or larger memory option, what other choice do I have please?

That is something you really need to discuss with Digi Sales. There are options available that are not always listed on the web site that Sales can help you determine such as the use of a memory card for storage.
