where is qpi/vtt for Asus z87 plus board

[jdl92990]

As the title says. I can't seem to find the qpi/vtt setting for my Asus z87plus mono. I know some brand use different names like Vccio. I don't have either of them. Is there anybody out there that can help. The issue I'm having is I keep getting BSOD error 124. Based on my guide it says try qpi/vtt first then try vcore. But as you can guess I can't find the qpi/vtt setting. Thank you for your help.
