iGPU won't disable?

[orangecat]

So a little while ago I was overclocking my onboard graphics and my system memory and for some reason my iGPU won't stop using my system memory. I'm running memtestx86+ and its only showing that I have 7617mb if memory available. I have set everything in my bios to disabled/auto to see if it would disable but the only way I was about to get it to disable was when I loaded up optimized defaults. Even after I set everything up the way I want it still uses up memory even though it shows up as disabled.

I have a Asus P8-Z77M Pro.

 

As you can see all 8GB isn't available but there isn't a second display adapter...

What was your available memory prior to oc your onboard?

It must be a setting in the bios that you have missed, it might just be easier if you write down all of the changes you want to restore in the bios on paper and load optimised defaults and change only the settings that you had written down to restore before booting.
