2008r2 only shows 4 cpu instead of 8 vmware 5.5

We are running VMware 5.5, vm version 10 - I have 1 2008R2 Standard server that has 12 CPU(s) (so I know it can be done).

I am trying to increase from 4 to 8 on a different 2008R2 vm.   I get 8 in device manager but only 4 show in task manager.

I seem to remember something having to be added to act like I had 2 cores with 4 processors each but I can't find it - having to do with windows 2008R2 standard only supporting 2 cores.

Maybe I added something in vm options, advanced, edit configurations??  (the one with 12 is running and I can't take it down to investigate)

Ideally, you would add sockets, not cores, unless you have a specific licensing requirement, where you are licensed by cores. Back to question....

see here

Windows Server 2008 Standard Edition supports up to 4 sockets and up to 64 logical processors


8 In Device Manager, and 4 only in Task Manager, suggests licensing restriction, of sockets in Standard Edition.

The other server, you have, how have you configured cores versus sockets ? (in the VM Settings, under CPU)
