Q6600 G0 CPU - no VT-x support?

[VirtualLarry]

I don't get this. I thought that the Q6600 chips supported virtualization.

In CPU-Z, on my Q9300, it lists VT-x under supported instructions.

On my Q6600, it does not.

Why is this? Is it due to the different OS (Q9300 is running Win7 HP 64-bit SP1, Q6600 is running XP 32-bit), or is something else going on?

Edit: Also, CoreTemp reports a VID of 1.3v, and CPU-Z says that the vcore is 1.216v, under full 4-core prime95 load. Isn't that a lot of vdroop?

Edit: Mobo is a Gigabyte EP35C-DS3R, BIOS F1 (first shipping BIOS, I think). They are up to BIOS F4 on their site, perhaps I should update it.

I don't actually need virtualization, at this point, on this box, but it just seemed curious that it didn't show up in CPU-Z.

Q6600 should have VT-x. Is it disabled in your BIOS?

 

[VirtualLarry]

I just rebooted, there is an entry in the BIOS for "Virtualization Technology", and it defaults to "ENABLED".

All versions of the Intel® Core™ 2 Quad Q6600 that were released have VT-x support. Which board are you using? Maybe there is something on the board that is stopping you from getting VT-x support? If you are using a D945 board you may not have VT support off from the board. This site has a listing of Intel board that has supprt for VT-x and VT-d (a much smaller list) http://www.intel.com/support/motherboards/desktop/sb/CS-030922.htm?wapkw=%28which+intel+boards+support+vt-d%29.

Ok I looked up the EP35C-DS3R and it supports VT-x. So I am at a loss of where to go from here.

Load BIOS defaults or try a BIOS flash!

Update the BIOS for sure. My q6700 (functionality the same) runs 64-bit VMs in VM Player without a problem which means its there.

Specifically, I had an AMD Gigabyte board that exhibited the same behavior with its ancient, original bios and the bios flash cured it.

Just use the utility, its easy!

I put Win7 64-bit on that machine instead, and now CPU-Z reports VT-x support. Did not flash BIOS.
