i7-3610qm vt-x enabled in BIOS but not available in VirtualBox

[KKole1]

Recently I started using virtual machines on this cpu. More recently (two weeks ago) I tried to run a 64bit VM and VirtualBox throw me an error for not supporting 64bit VMs (as it came out after I checked). As far as I know this cpu supports vt-x which is responsible for the 64bit virtualisation. The computer is Asus K55VD. A couple days after those errors my bios died. I changed the chip and now the computer is working but still no 64 bit VMs for me. The problem is that I'm not sure if I had this VT-x or not and when/how it disappeared. I just wanted to know if is it possible for the cpu to lose this particular instruction and because of that the bios to die or from the beginning I haven't had vt-x and for now I've just being lucky working with 32bit VMs

Hi Kolyo,

Intel® Virtualization Technology (VT-x) is supported by this processors, see the following URL: http://ark.intel.com/products/64899/Intel-Core-i7-3610QM-Processor-6M-Cache-up-to-3_30-GHz ARK | Intel® Core™ i7-3610QM Processor (6M Cache, up to 3.30 GHz)

What error message are you getting from VirtualBox?

Sorry for the late answer but anyway. The message from VB is something like: "VT-x/AMD-V hardware acceleration is not supported on your system. Your 64-bit VM wont be able to detect 54-bit CPU and wouldn't be able to boot. (I'm translating on the go, because my VB is not in English.)"
