Ignoring the fact that RAM usage is good in database servers, this one failed the "no research effort" sniff test for me. I am not a Windows guy, but was able to find a straightforward answer to the OP's question, direct from Microsoft Documentation, with a single Google Search.
Server Fault should not be a replacement for reading documentation. If a user won't at least consult the freely-available documentation on a simple issue like this, then frankly they don't deserve the free assistance available here. Don't take that as mean-spirited, I don't intend it as such. My position on this is comes from the viewpoint that it's far better to encourage people to find answers on their own than to spoon-feed them one-off answers on demand.
