Can i turn of intergrated graphics on asus z87 sabertooth

I am planning a new build with a z87 saberooth, form teh asus TUF series. But i just read it has intergrated graphcs wich take up to 1 gig of shared memory. And since i got a GTX780 i really dont want that intergrated one taking up 1 gig of my memory for no reason..

Disable it via BIOS

If thats an option, yes. on my other computer i can only turn DOWN the IGPU, not turn it completely off...

You should be able to turn it off through bios settings as @PredatorRules stated. I can't see why it should use any RAM anyway since you are showing the picture through the 780.

Like i said, on my other computer i cannot turn OFF the intergrated GPU. And so it will always reserve RAM for its purpose prior to anything else.. I would also prefer the opinion of someone who own the board.. because SHOULD be able to, is only "should"..
