It is better not to buy without good cooling.

21 May 2020

I bought it for the server. Almost burned out during tests, and the RAM frequency wasn't satisfying. It's better to buy several gaming modules than this one. Now it's just sitting on the shelf.

Large amount of RAM
Price

Weak frequency
You can boil water on the bar.
