 Maximum memory setting not working

I've explicitly set the Maximum Memory value in SQL server 2008R2 to 13000MB but when I check the task manager I see it is using 14,071,448KB (13,741MB)

The reason I'm concerned is because we set the maximum value because the server crashed recently due to a low memory condition where SQL server had allocated almost all of the server memory.

I've checked and the number I have entered is correct (i.e not entered in kb by mistake)

Any ideas?

SQL Server is in serious need of memory.You need to urgently increase the RAM in your SQL box.

Max server memory sets the size of the buffer pool. There is some memory taken outside of the buffer pool for things like thread stacks, CLR, backup buffers and a few other things. It's ususally not a lot of memory.

Reduce the max server memory a little (maybe by 500 MB), that should get the memory allocated back into the range you want.

Note that this is not a sign of memory pressure, it's normal behaviour.
