I have a Virtualbox VM running Windows 7. When I open Start -> Right click "Computer" -> Properties, I get the real CPU name and plausible CPU speed (not sure if it's exactly the same).

Now I want Virtualbox to change the CPU name to something different, say an old Core 2 Duo running at a lower speed. How would I do that?

  • That one's not answered. I'd wait and see if this does any better.

  • I've just answered it. Does my answer work for you, too? Jun 28, 2014 at 23:13
  • It says "Intel(R) Core(TM)2 CPU (big space) 6600 @2.40 GHz (space) 3.36 GHz" which is not very convincing. I think the 2.40 GHz is part of the CPU model information, while the 3.36 GHz is the reported current CPU speed. How do I change the reported clock speed?

  • I don't think that's possible. And after all, most modern CPUs have variable speed thanks to their power management features and overclocking. If you want to limit the speed, I suggest editing your question accordingly mentioning that you've already figured out the model name part. By the way, there's already a similar question on this topic: "Limiting CPU speed in a virtual machine". Jun 29, 2014 at 0:13
