Well I assume 64 bit so

Really, as high as you want BUT with so much RAM, setting a high virtual memory is probably just a waste of space.

I'd just set it to be Windows managed, and let it grow as needed. Monitor your server, if it's using virtual memory, then you need to add more RAM.


Would help to know what this servers task is. If it's a file server, you could remove all your RAM and just keep a 512 stick in there. If its a database server, then Virtual memory should be unnecessary because using it would cause huge backlogs on SQL requests

If this is a VM server, Virtual memory can be pretty much turned off as VM's reserve a preset amount of RAM for themselves from the Host.

If this is an RDP server, then I would set the virtual memory to 32gb or Windows Managed.

Max RAM for 32 bit is less than 4 gigs.

Generally speaking it should be

1.5 times the amount of physical memory. In your case that would be 24GB. I like to set it at 0, then reboot, defrag, and set it to a static number i.e. 24GB min, 24GB max.

If you really want to tweak it as close to actual requirements as possible, look to perfmon to determine your needs. Here is a nice article and discussion;

OK your problem here is the OS

by OH Smeg In reply to Right Virtual Memory Conf ...

As it is a 32 Bit OS it can not map or use more than about 3.2 GIG of RAM so you can effectively remove all but 1 X 4 GIG Module as I'm assuming that you have 4 X 4 GIG Modules installed and you will not notice any determent to the performance. If anything it will be cheaper to run as it will be using less electricity that way.

Unfortunately there is no 32 Bit OS that can Map more than the 3.2 GIG of RAM so if you need to use more you need to be running a 64 Bit OS of some description.
