AS stated here如此处所述

SQL Servers max memory setting defines the limits for buffer pool usage only. SQL 服务器最大 memory 设置仅定义缓冲池使用的限制。 There will be variable but significant allocations required over and above that limit.在该限制之外，将需要进行可变但重要的分配。

Min & Max Server Memory最小和最大服务器 Memory

Microsoft SQL Server Management Studio → Right Click the Server → Properties →Memory → Server Memory Options → Minimum server memory (In MB): = 0 and Maximum server memory (In MB): = 2147483647 Microsoft SQL Server Management Studio → Right Click the Server → Properties →Memory → Server Memory Options → Minimum server memory (In MB): = 0 and Maximum server memory (In MB): = 2147483647

Configure this memory allocation Based on the RAM installed in the DB Server.根据安装在 DB 服务器中的 RAM 配置此 memory 分配。

For Ex:例如：

IF DB server is installed with 6 GB of RAM , then maintain the 20% breadth space for the OS installed in the server.如果 DB 服务器安装了6 GB 的 RAM ，则为安装在服务器中的操作系统保持20%的宽度空间。 For 6 GB of RAM, Maximum server memory (In MB) will be = 4915 for the SQL server.对于 6 GB RAM，SQL 服务器的最大服务器 memory（以 MB 为单位）将为 = 4915 。

Right Click the Server → Properties →Security → Login Auditing → Enable the Failed logins only.右键单击服务器→属性→安全→登录审核→仅启用失败的登录。 This option will avoid the log write and memory log space will be saved.此选项将避免日志写入，并且将节省 memory 日志空间。
