Graphics Kernel Panic

[nextsak]

My first build
GIGABYTE Z170X ULTRAGAMING
i5 6600
16 GB RAM

Mac OS Sierra 10.12.1
BIOS just the basic settings

Suddenly Kernel Panic at com.apple.driver.appleintelSKLGraphicsFramebuffer
the only way to boot is to alter DVMT pre Allocated from 32M to 64M.
Now every boot says there is a problem at the bios. Load settings and manage to boot again.
I also lost my imessages.

Can anyone please check my config?

Two thoughts, first, your default resolution is a little high, 2560x1600, you might bump that down to 1920x1280. Not sure that would cause a problem.

But also there is a block of text at the bottom that makes the entire plist invalid from an xml format perspective: the block

<key>Devices</key>
<dict>
    <key>AddProperties</key>
    <array>
        <dict>
            <key>Device</key>
            <string>IntelGFX</string>
            <key>Key</key>
            <string>AAPL,GfxYTile</string>
            <key>Value</key>
            <data>
            AQAAAA==
            </data>
        </dict>
    </array>
</dict>

is not where it needs to be, so double check what you're trying to do that and move it into the right place of the config.plist. I wouldn't even think Clover Configurator would validate the config this way!

Are you able to get to the Clover boot screen or not? I'm confused. I used DVMT of 64MB myself, I think that's pretty recommended config, some even say higher but I haven't found a compelling reason yet to go higher. And for what it's worth, if I have any sort of BIOS issue, I reset the cmos, load optimized defaults, and re-hand-tune my BIOS being deliberate about changing fewer rather than more things, you don't want to go nuts changing lots of stuff especially if you don't understand it, and there is a lot of stuff in there I don't fully understand. If you're having a problem simply getting to the installer or the desktop, you want to make small changes one at a time and retry until you get to the desktop, then you want to be super careful about making more changes. Same with clover boot args, don't add a bunch at once, deliberately try adding one or two at a time. Usually clover boot arguments while installing are things related to graphics card, so you might try removing your discrete GPU until you get a working OS on the iGPU then worry about the discrete GPU, if you even have one.

Thanks,
Yes i boot.
My resolution is hi, cos its native for my apple cinema display 30". Do you think to use a lower one at startup?

The block of text is corrected now by Clover Configurator. I was trying to fix screen glitches. https://www.tonymacx86.com/threads/skylake-intel-hd-530-graphics-glitch-fix.206410/.
Now it is ok.

I found the hard way that DVMT of 64MB is pretty recommended.
I already reset the cmos and change as little as possible.

My only issue now is to figure out what I have to do with USB 3.0 not working.

I also lost my imessages.
Was working allwright with https://www.tonymacx86.com/threads/an-idiots-guide-to-imessage.196827/
Maybe I will start again.

Here is my new config.

You don't have an MLB set in your config which is likely why iMessage isn't working.

I have all the correct values in clover configurator.
I also see the numbers into the config.
Do i have to do anything special?
Sorry if i ask nuts, but It is my first time with all these

I looked at your config, there is no MLB value.

Sorry, my mistake.
Did not follow the guide all the way.
I will try again.

Thank you

The guide is says

From the ROM dropdown list select UseMacAddr0
Make sure that the MLB box is empty
Set BooterConfig to 0x28
Set CsrActiveConfig to 0x67
