It's already disabled unless you've changed the BIOS default settings under Advanced > System Agent > Graphics Configuration. (See s3.5.4 of the manual.) In fact, the defaults won't even call for you to install the Intel Graphics drivers.

The "key" is the iGPU Multi-Monitor setting (Enabled/Disabled). Default is DISabled, but if you ENable that one, it's also advisable to set the Primary Display setting to PCIE assuming that's what you want. Leaving the latter setting on Auto can produce some unintended results when iGPU Multi-Monitor is enabled.

if is that true, why in "Control Panel\System and Security\System" in system Section write : Installed Memory (RAM) : 32.0 GB (31.8 GB Available)
remnant memory shared with iGPU.

Presumably because the amount of system memory allocated to DVMT 5 has been set under Advanced > System Agent > iGPU Memory. It's independent of those other settings. With 32GB available I wouldn't expect it to cause any major "shortage." :-)

Correction / clarification: There are some indications elsewhere that Windows may make its own DVMT allocation from system memory regardless of that BIOS setting. See, for example, the Intel Support Community thread at http://communities.intel.com/message/126140

Can't confirm that myself, but thought I should pass it along FWIW.

Before and a while after i got my new Ivy Bridge computer (P8z77-v Deluxe + 3770K) i also wanted the iGPU dead and buried ... But after seeing what it can do i'm really happy its there.

If you want to convert movies, the iGPU will assist when Intel Quick Sync is available, and convert much much faster then using CPU alone and provide better quality then AMD/Nvidia GPU converted movies !!
