Z87-G41 PC Mate (MS-7850) IOMMU unlock
#1
Hello,

I was wondering if someone can enable the options for IOMMU on this board? I cannot see the setting for VT-D anywhere. 

This is the support page: https://www.msi.com/Motherboard/support/...#down-bios

Thank you!

bios path :Overclocking > CPU Features > Intel VT-D Tech
The default of Intel VT-D Tech is enable.

I've already been to that menu and it is not shown. I don't know why this is. I'm using an i7 4770K

The reason is very simple ,i7-4770k didn't support vt-d ,so bios will not show this item and vt-d is enable with default value ,if your 4700k support vt-d the feature should running normal.

These are i found in internet.

AAh OK. Thank you so much! That sucks how it's disabled on this CPU, even though a 4790K is basically the same chip x_x
