In most cases, the computer manufacturer has already configured the system to use the maximum amount of graphics memory that is possible for your particular computer model. Sometimes you can change these values through BIOS level.
Check with your computer manufacturer if there are tips on increasing the amount of graphics memory for your computer model.
If you are interested in additional information see graphics memory frequently asked questions:
I have had EXACTLY the same response to a similar post by me. It is rather frustrating that a lot of people are asking the same question only to get a worthless spiel back from the Intel forum staff.
However, to be fair to the forum staff, I suspect that Intel do not have a decent response as (1) adjusting the DVMT values has no effect in Windows 7 (and Vista I believe) and (2) the driver development is out of their hands. The driver and the Intel utility would, of course, be the best place to sort this gross oversight out and to hand control back to users...
To the Intel staff who are responding to these posts with the same rhetoric time and time again,
Please can you pass on all these messages to your development team and emphasise that users WANT to be able to adequately control the graphics RAM allocation in their PCs. The i3/i5/i7 series CPUs have a built-in IGP that uses DVMT - great! Now let people choose to disable the DVMT and allocate a fixed amount because it doesn't work properly!
