there is no difference at all...

Serial ports should be disabled in the BIOS settings.

WOW! Eagle's eye to spot the problem others have overlooked!

It happens so often that I am used to looking for it now.
It's not so important with 8 series boards and may not help at all but for sure it will not do any harm to disable it.

You mean I need disable every non used serial port under Peripherals/SATA Configuration ?

No.
Serial ports should be disabled not Serial ATA (SATA) ports.

I don't see option to disable it in bios.. but as you say this setting probably are irrelevant.

In my system is also 32gb of ram but they working 100% on windows and el capitan.

Keep digging in your bios, Gigabyte Z series boards definitely have that setting. Look for SuperIO settings.

I figured you had that disabled already, the changes I made were inject Kexts instead of detect, and a CPUID for Haswell (sometimes it helps).

Look at page 58 of your motherboard manual :

Super IO Configuration
This section provides information on the super I/O chip and allows you to configure the serial port.

Serial Port A
Enables or disables the onboard serial port. (Default: Enabled)

The truth is, you see only what you look for and recognize what you know.
I missed it even when that line was really staring at me!
I hope this finding will help the OP to fix his problem.
Thank you P1LGRIM for your diagnostic acumen.

I just noticed that he has a GTX 660 Ti, i sense that this is not going to end well.
