RS812+ compatible RAM upgrade

MAX Synology RAM for RS812+

Hi, I was hoping you can help me with the maximum amount of ram I can use with my Synology RS812+

The NAS is obviously older, but still runs great, however RAM availability is getting low due to running a number of Docker containers and is causing DSM to crash occasionaly.

I currently have 2GB ram. (2x1GB)

I have read that the processor can handle 4GB but Synology says max of 3GB


If the first RAM module is not soldered on the motherboard, you can remove it and replace with something faster (therefore limit 1GB+2GB=3GB).  By default, you get 1333MHz model. Often CPU limits mean – per lane. So it would be 2x4GB. But this is something you can experiment with thanks to Amazon free returns.

CPU Frequency Dual Core 2.13 GHz
Memory DDR3 1 GB (expandable, up to 3 GB) 204pin SO-DIMM DDR3 – 1333MHz , Unbuffered, 1,5V

This RAM also fits RS814+, RS814RP+, RS812+, RS812RP+.


On eBay they sell 2GB memory sticks
