Intel Mobo provisioning:
set VTd INTEL VIRTUALIZATION to DISABLE.
set ONBOARD AUDIO/SOUND (AZALIA) to DISABLE.
set IEEE1394 to DISABLE.
set PCI-E SUBSYSTEM/LANES to x8/x4/x4
set ONBOARD GRAPHICS to DISABLE.
set PCI-E GENERATION to GEN2.
set CPU FREQUENCY SCALING to DISABLE.
set CPU PERFORMANCE MODE to ENABLE.
set FAST BOOT to DISABLE.
set CSM to ENABLE.
Few things different than what I know to be the best settings.
set ONBOARD GRAPHICS to DISABLE, this needs to be enabled nvidia or amd, onboard gpu that comes with the cpu is very recommended.
set PCI-E GENERATION to GEN2, this needs to be gen1.
Any cpu overclocking must be off. Any memory settings must be left on auto.
Any port that will not be used must be turned off in the bios too.
set CSM to ENABLE, this must be on on amd and off on nvidia, uefi on nvidia works better.
