No 64bit option in Virtualbox

[Italiandogs]

Hi there I am trying to run a 64 bit version of windows on my computer using Virtualbox. The problem is that there is no option for a 64 bit only 32 bit. I've already looked into this and have read elsewhere that you must enable virtualization in the BIOS and disable Hyper-V is the Windows Features. The problem is I have neither of these options.

p.s. I am using VirtualBox 4.3.20

Here are my system specs:
-Intel Xeon 3.60 GHz (3.59GHz) [2 physical CPUs]
-16.0 GB RAM
-Windows 7 Professional 64bit
(The computer that I am using is a Dell Precision 670 Workstation)

I ran into this yesterday.

Currently running Win 7 x64 on a Shuttle XPC SP35P2 Pro. I was surprised, as you were that I could not run 64-bit VMs.

In my instance, the CPU is the culprit. I have an Intel E7200 / LGA775 CPU - which does not support virtualization. I will swap that out for an E8400 or possibly a QX6850 to allow 64-bit VMs to run.

The 3.6 Xeons used in the 670's do not support VT so you're out of luck. The 690 uses the Xeon 5345 which does. They are not interchangable.
