Clear CMOS, sets dGPU as default

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I have an Extreme4 Z270. Which has an A BIOS and B BIOS

#1 When I clear the CMOS/BIOS (short pins 2&3 on MB) as per manual.
The BIOS goes back to a default (seemingly) whereby the iGPU does not work, In other words the MB only accepts a dedicated graphics card by default. and does not display graphics when BIOS reset.

#2 As a side I also have to remove the Memory and reseat it when I clear the BIOS. otherwise I get no display.

Why does it default to dGPU?
And can I change this behaviour?
