How much RAM should a SQL Server have?
The minimum requirements are easy to meet: at least 3 GB of RAM and enough hard drive space to hold their data warehouse, staging database, and cubes. However, meeting the bare minimum is often not the ideal solution and providing better hardware to your server will allow for improved run-times and efficiency.
How much memory does SQL 2016 need?

How much RAM does a file server need?
File servers do not need high performance, low latency, high frequency RAM. FreeBSD, FreeNAS, and Ubuntu all run well with 2GB of RAM under loads typical of a home file server, but they do run palpably smoother with 4GB. WHS2011 runs much more smoothly with 4GB. All of the file server OS’s run even better with 8GB RAM.

Does SQL use RAM?
SQL Server is designed to use all the memory on the server by default. The reason for this is that SQL Server cache the data in the database in RAM so that it can access the data faster than it could if it needed to read the data from the disk every time a user needed it.
What happens when there is low free memory in SQL Server?
If there is low free memory for the OS, SQL Server will release memory back to the operating system until the low memory condition is alleviated, or until SQL Server reaches the min server memory limit. However, you can override the option to dynamically use memory by using the min server memory, and max server memory server configuration options.

Too little memory used is also often not a real problem, rather it’s usually from using the wrong tools to check SQL Server’s memory usage. Let’s start by looking at an example. This particular server has 16 GB of memory, and SQL Server’s max server memory is set to 10GB.
