The chipset is the same. You only have more connections:

Also I've a
Micro ATX Form Factor; 24.4cm x 22.5cm and you an ATX Form Factor; 30.5cm x 22.5cm.
But what have you done exactly? How do you have made your bootable USB-Stick?
I made this.
I followed the guy in the video:
1. I made one partition with the "Mac OS Extended (Journaled)" format as GUID Partition Table.
2. I followed the normal steps to make a bootable OS X USB-Stick.
3. I used the program Pacifist to dragged the mach_kernel and dropped it directly on the Stick.
4. I downloaded the Extra file (Extensions.mkext, com.apple.Boot.plist, smbios.plist) (description of the video) an dropped it directly on the Stick.
5. I deleted the AppleHDA.kext, repaired permissions and rebuilt cache.
6. I disabled VT -d in the BIOS.
Stil the CPU-caller error..
Ok, i think you may have got yourself in a bit of a pickle. If you haven't got a working system I would be inclined to do a new installation and reset your BIOS settings back to default.
The installation method I used was the normal Tonymac Chimera (latest) way found
here. It essentially consisted of making a bootable Mavericks 10.9.3 USB with the help of Unibeast (you do need another mac or hackintosh to do this).
I didn't change much in the BIOS, disabling Virtualization and tweaking the memory multiplier to 16 so it can run at full speed. Make sure you change the BIOS settings before you start your Mavericks installation. I will try and get some screenshots of my BIOS up here when I have some time.
Booting to the initial installation screen was easy and required no boot flags once I chose the USB stick as the bootable device (hit F12, select your Mavericks USB). The installation ran fine and once it completed I then restarted and booted back to the USB device, this time selecting the new "Mavericks" partition. Note that I could not get past the loading apple screen to finish the setup - so i used -x -v to complete the setup.
Once this completes reboot the system and select your new hard-drive rather than the USB. Again you will have to type in -x -v to get to the desktop.
From here you can follow my guide I posted a few pages back. From a new installation without ANY multibeast settings, there was only one AppleHDA kext (not controller - you want to delete the audio kext) in the
System/Library/Extensions folder.
Do not apply multibeast settings until you have got your desktop stable - so you can pinpoint which kexts may have screwed your desktop, and work backwards from there.
