DL380p Gen8 Running Windows Server 2012 Std., Problem with Intel Virtualization Technology/VT-x

Hi,

i'm having issues with a DL380p Gen8 (Xeon E5-2630) not recognizing Intel Virtualization Technology. In the BIOS all options are enabled (No-Execute Memory Protection, Intel Virtualization Technology, Intel VT-d). I powerd down the system completely but still "Intel Processor Identification Utility" tells me there is no Intel Virtualization Technology and no VT-x. Coreinfo.exe also tells me the same.

BIOS is up to date with version 2014.02.10 (A).

Any help is greatly appreciated,

Klaas
