My server have 14GB Ram, I installed Windows Server 2008 R2 Standard and activate using Windows Loader ... all OK But I've upgraded from Windows Server 2008 R2 Standard to Enterprise ... Later I activate using Windows Loader ... all OK After rebooting, windows can see the RAM but in the system panel will display: Installed memory (RAM): 14.0 GB (8.00 GB usable) I have found that this problem can occur by activation of Windows. en.community.dell.com/support-forums/servers/f/956/p/19363950/19818149.aspx serverfault.com/questions/229390/after-upgrading-to-2008-r2-enterprise-and-installing-more-ram-windows-can-only How could I fix it?? Thanks you.
Did you try to uninstall the Loader to see what happens ? How is that related to the problem in any regard ... ? For chit chat use the Shout Box .
