Synology 1815+ comes standard with 2GB of RAM. I got an 4GB block out of an broken laptop. And I use it to upgrade my NAS to 6GB of RAM.

My PlayHouse is a channel where i will show, what i am working on. I have this house, it is 168 Square Meters / 1808.3ft² and it is full, of half-finished projects.
I love working with heating, insulation, Servers, computers, Datacenter, green power, alternative energy, solar, wind and more. It all costs, but I'm trying to get the most out of my money, and my time.
