Hey guys,
Disclaimer: I am not a seasoned Ubuntu user but only a pleb learning to run Umbrel, so please be patient with me 
So Iām running my node with Umbrel on Ubuntu. I have now decided to upgrade my 4GB Ram to 8GB Ram.
Umbrel is still showing a 4GB Ram capacity. However, this is what I managed so far:
1- increase swap file from 4GB to 8GB
2- ran commande Docker stats and I see that all my containers have a 8gb limit.
Not too sure what else to do 
Thanks for the help!
