Not many people realized this, but [Synology has their own brand of RAM](https://www.synology.com/en-global/products/DDR3).

Officially, Synology always recommends you to use their brand of RAM for 100% compatibility and reliability. It comes with three years warranty and is made in Taiwan.

There are two types of Synology RAM, [SO-DIMM](https://en.wikipedia.org/wiki/SO-DIMM) for prosumers and [ECC Module](https://en.wikipedia.org/wiki/ECC_memory) for enterprises.

For the ECC module, there is only one variant which is RAMEC1600DDR3, and it is available in 2x 2GB, 2x 4GB or 2x 8GB configurations.

For SO-DIMM, there are three variants, D3NS1866L, RAM1600DDR3, and RAM1600DDR3L.

Both the D3NS1866L-4G and RAM1600DDR3-4G are available in 1x 4GB and hence the -4G at the back of the model number.

The RAM1600DDR3L is available in 2x 4GB or 2x 8GB, and hence the model number is RAM1600DDR3L-4GBx2 and RAM1600DDR3L-8GBx2 respectively.

If you are a consumer, you probably just need to get the D3NS1866L-4G which is meant for [DS918+](https://www.synology.com/en-global/products/DS918+), [DS718+](https://www.synology.com/en-global/products/DS718+), [DS218+](https://www.synology.com/en-global/products/DS218+), and [DS418play](https://www.synology.com/en-global/products/DS418play).

The D3NS1866L-4G is a 4GB DDR3L-1866 unbuffered 204-pin SO-DIMM running at 1.35V. The RAM itself is manufactured by [SK hynix](https://www.skhynix.com).

Since I am going to upgrade my [DS216+](https://lesterchan.net/blog/2016/02/05/synology-diskstation-ds216/) to DS918+ and [DS415play](https://lesterchan.net/blog/2014/11/07/wd-red-with-synology-ds415play) to DS418play, I have gotten two units of D3NS1866L-4G.

The upgrade will expand the RAM of my DS918+ from 4GB to 8GB and DS418play from 2GB to 6GB.

You can get Synology RAM from [Storage Studio](https://www.storagestudio.com.sg/) starting from next month, December 2018. I am still waiting for the local price, but the official RRP for the D3NS1866L-4G is US$70 (S$96).
