I mean sure but. I’d be surprised if you wpuldn’t see a difference between 1 stick of 8 and 2 sticks of 8. Me going 16gb RAM to 32gb RAM was one of the most noticable upgrades I have done. Similar amount of change from going 1080p to 1440p of my monitor.
Somebody is going to have to explain to me how starlink is going to boost WiFi availability if it is routed from offsite using their current fibre network.
