I'm willing to enable the VT-X virtualization technology on my Intel Core i5 3450 CPU, however in the BIOS menu (I've the latest version: 17.8) of my MSI B75A-G41 mainboard, this option is greyed out even though it should be supported by my CPU.
"Bios menu with the VT-D option greyed out"
CPU-Z Report stating that my CPU does support VT-X:
Does someone know why the option is greyed out even if the "Intel Virtualization Tech" option is enabled and works fine?
Maybe do I need to install some Intel software that will activate the option on my CPU? Here are the different available utilities for my mainboard: http://www.msi.com/product/mb/B75A-G41.html#/?div=Driver
I could install all of them but I don't want to because it would slow down my computer for nothing.

Your proccessor does not support virtualization technology VT-D (source), CPU-Z is correct, your CPU does have VT-x and is enabled by default as MSI utility states (
Intel Virtualization Tech - [Enabled])VT-d is Intel® Virtualization Technology for Directed I/O, and MSI utility is correct once again
Intel VT-D - [Disabled]), because it is not supported.You cannot enable something that is not supported.
