Allocate memory for a virtual machine

In Virtual PC, do one of the following:
- If you have only one virtual machine, on the PC menu, click PC Settings.
- If you have more than one virtual machine, on the Window menu, click Virtual PC List. Click the virtual machine you want, and then click Settings.
  Note You cannot change the memory allocation if your virtual machine is in a saved state. Start up your virtual machine or shut it down to change the allocation.
Click PC Memory.
Under PC Memory Settings, drag the slider to set the amount of RAM or VRAM.
Do one of the following:
- If your virtual machine is not running, click OK.
  When your virtual machine starts, the new setting will be in effect.
- If your virtual machine is running, click Restart.
  You must restart the virtual machine for the changes to take effect.

Notes

The RAM setting corresponds to the amount of RAM installed on the virtual machine and does not correspond directly to the amount of RAM used by the Virtual PC application.
The VRAM setting determines the maximum screen resolution the virtual machine can support. Higher VRAM settings may impact the performance of the virtual machine and should be used only when necessary to achieve maximum resolutions in full-screen mode.
