Z87X-UD5H with VT-x problem

Z87X-UD5H with VT-x problem
« on: August 05, 2014, 09:36:50 pm »

So I'm trying to develop some android stuff and I read about something called HAXM which would speed up the android emulator on my computer alot.
So I check in my BIOS there's a bunch of options which are greyed out (why can't I change these?). I also did update to the latest beta bios to see if that would help, but it didn't make any difference for this problem.

One of the options were VT-d which was ENABLED but greyed out.
Another option: Virtualization Technology was however ENABLED and I could change that one. But I want Virtualization but with VT-x
So I try to install HAXM and it says:
"This computer does not support Intel Virtualization Technology (VT-x). HAXM cannot be installed. Please refer to the Intel HAXM documentation for more information"
So I visit this web page: where it says my processor i7 4770K does indeed support VT-x
But is the problem that the motherboard does not?

In Windows 8.1 I have a program called CrystalCPUID and it shows that VT is not enabled.

Anyone have any clue about this?

Just so you know - the link you posted is not for your chip.
It's for a vanilla 4770.

The 4770k DOES support VT-x but not vPro or VT-d

So if your app needs these extensions as well then it will not work.

I know from experience that installing ESXi from Vmware to be problematic on K series chips as it needs the missing extensions.

Doesn't really answer your questions but hopefully provides some more info.
