ESXi 5.5 increased CPU on W2K8 - not listed in system properties or Task Manager

[milty2016]

On ESXi 5.5. doubled CPU - 2 to 4 on a Windows 2008 server. The CPU count is listed in Windows Device Manager but not Task Manager - shows only 2 CPU's. System properties lists 2 CPU's. Thought CPU in 2008 and on were hot add/or do I need to also update/upgrade the HAL? Or am I good?

Thanks,

Milty

This depends on the license of 2008 you have. Only Datacenter supports CPU hot add.

I have Windows server 2008 R2 Standard SP1. What's odd is Device Manager does list 4 CPU's. So it seems to see it "hot added" but not System Properties or Task Manager.

See below.

That's how it's supposed to look. Device manager registers the additional CPUs, but Windows will not begin to use them until you've done a reboot. As I said, Standard license does not entitle you to CPU hot-add in 2008.
