Dell Optiplex 745 not 64 bit

Hi all,

I'm having an issue with a Dell Optiplex 745 (desktop). The CPU installed is the Intel Pentium D 800MHz 3.4GHz. In the BIOS it states it is 64 bit technology, however I do not see the option under performance to enable VT. I've tried upgrading the BIOS to the latest version (2.6.3) but alas to no avail. Has anyone come across this issue before?

Thanks in advance

  1. 64-bit doesn't automatically imply support for VT. According to, VT is supported when using the following processors only:

    Intel® Core™ 2 Duo (E6000 series)
    Intel® Pentium® D (900 series)
  2. Ah thanks.

    I ran CPU Z and turns out the processor is a 945 model which unfortunately does not provide support for VT.
