Kernel Panic after changing RAM frequency

[mistergonzo_x86]

Hey there,

i assembled my first Hackintosh Build today and installed everything via you know what (sorry, really wanna get into it first and get it to work)

Since I'm a relative beginner (to linux based terminal etc etc in general) I am not very familiar with the debugging technics.

 

The scenario:

 

Everything worked fine so far (RAM at 1333Mhz), but my BIOS/EFI didn't recognize the 1600 Mhz of the RAM directly.

So after enabling the XMP in the EFI my Mac won't boot and give me a Kernel Panic.

 

Are there any known issues or workarounds?

 

My Setup:

 

GA Z87X d3h (it has Bios F8 which seems to be the latest not in beta state)

Crucial Ballistix Tactical 2x8GB 1600Mhz

Haswell  i7 4790k

no extra GPU

 

I think the rest doesn't matter for this issue.

Would be great if someone had a solution or a hint since i want to use the full potential of the RAM.

 

Cheers

Ok, I figured it out - by changing the RAM Voltage Manually to 1.5V it worked somehow. Maybe the XMP didn't apply the changes or I was too stupid for it.

Now I have the 4.3 Ghz OC limit on the CPU - but I have to get into over clocking first to raise this up maybe.

 

Thanks anyway
