SQL Server 2000 memory usage

Hi All,

background
windows 2003 server standard
ms sql2000 standard

i have read that sql 2000 can only access 2GB of memory and also that 2003 server std can only access 4GB,

is there any way to increae this?

is this per sql instance? ie if i have 2 instances can i now access 4GB, 2GB per instance?

currently have 1 instnace with 3 databases of varying sizes. i have 3.5GB of memory and yet still using a 2.5GB paging file.

i have done the usual of seperating the logs onto another disk etc to try to gain speed however still a very large number of page faults all on disks.

any ideas warmly accepted

thanks
gareth

Windows XP Professional and Windows Server 2003 Memory Support. The maximum amount of memory that can be supported on Windows XP Professional and Windows Server 2003 is also 4 GB. However, Windows Server 2003, Enterprise Edition supports 32 GB of physical RAM and Windows Server 2003, Datacenter Edition supports 64 GB of physical RAM using the PAE feature.

No matter what you will need to leave some memory to the OS.

Also note that SQL 2K5 supports up to the amount that the OS can use.  So if you can use all 4GB

this is how i keep it in control:
1. set your windows swap file fixed, ie minimum = maximum size
2. set your sql server memory size fixed (not all mem. but most)

2.5 GB for fixed sql server memory, will do just fine.
