My Pf sense firewall uses 2GB RAM

[shehan31]

I am planning to upgrade pfsense firewall RAM from 2GB to 4GB. Do I have to change settings of it. Version 2.2.4-RELEASE (i386)

You'll have to switch to 64 bit to have 4 GB of usable memory. You're nowhere near using the 2 GB you have so not sure there's a pressing need to bump it to 4 GB. Still would be a good idea to switch to 64 bit assuming it's a 64 bit CPU.

So what will happen if I plug other RAMs.

You end up with more unused (wasted) memory.
