We've just added memory to our windows 2008 64 bit server.
It originally had 12Gb, and we added another 16gb to make 28gb.
Windows recognize the added memory but it says:
INSTALLED MEMORY 28GB (12 GB Usable)
And in Resource Monitor it says:
Hardware reserved = 16396MB
In Use = 12154 MB
Modified = 3MB
Standby = 117MB
Free = 1MB
Available = 118MB
Cached = 119MB
Total = 12276MB
Installed = 28672 MB
My questions are:
1. Can someone please explain what this means?
2. Is the additional 16 gb being used? I know windows recognized it (hence the "Installed" is 28GB) but why is the "Total" is only 12GB?
3. We run virtual computers on this server. Assuming 1 virtual comp is using 1GB, we hope to run another 16 virtual comp. But before we do that, I wanted to confirm that all memory are recognized and used?
