BIOS/UEFI Screenshots - Gigabyte Z77X-UP5-TH

I have this motherboard and running mac os x on the first try, but why must the Vt-d - Disabled? Mine still on and i seem to have no problems. I do plan to run fusion.

 

Is this still needed in k cpu's - I am curious if it affects the performance

 

Gigabyte Z77X-UP5-TH "K Chip"

I have Gigabyte Z77X-UP5-TH with the most up-to-date Bios as on 10/2015. There is no available option to turn Vt-d BIOS on/off. Doesn't even show the option. My chip is i7-3770K. I am guessing the "K" is why it does not show. Just fyi for anyone that runs across the same thing.

 

No Rodeo, I have GA-Z77-DS3H with 3770K and there is no Vtd

 

The screenshots seem to be missing one:

Internal CPU PLL Overvoltage: Disabled
(USB mouse/keyboard problem fix)

 

for the GA-Z77-DS3H:
Peripherals > SATA Mode Selection
You must set it to AHCI as the Default is IDE.

 

i also have this same board and can't see the VT-D thing in BIOS.

 

Read Stork's reply above. This setting is not required if you have the 'K' version of the processor. The BIOS just doesn't display it if you are running a 'K' like a 3770K.
