A lot of problems with P8H61 USB3 and ATI 6870

[msisoft]

At first...
This is my system:

MB: Asus P8H61 USB3 (Audio: Realtek ALC 887)
Graphic: AMD Radeon HD 6870
CPU: Intel Core i3

I used Unibeast to make a bootable usb.
I installed Mountain Lion completely. (before the installation, I removed "ATI6000Controller.kext" from USB/System/Library/Extensions )
after the installation, I put "ATI6000Controller.kext" in desktop and I used KextBeast to install it. (according to this page : http://www.tonymacx86.com/mountain-...mountain-lion-6xxx-gpu-issues-fix-inside.html )

but after the restart, it still can't know my graphic card and I have a very low resolution.

the main problem is...
when I install the MultiBeast, After the Restart, I can't boot to my OS (it gets a black screen). :?
( I only enabled "Realtek Audio ALC 887/888b Current" and "bootloader" in MultiBeast)

and another problem, when I use Mac OS, the fan of my CPU starts moving fast! (it is noisy!)
but the CPU usage is about 2~5% !
before, I heard this noise when the CPU usage was high (e.g. 90%) in the Windows.
I didn't install any DSDT, is it because of that?

If you know What I have to do, Please tell me.
If you know a tested way for Install ML on my system, Again Please tell me!
If you Know someone who installed ML on same system, give me his email.....

and last question...
Why I have to install my motherboard DSDT?
What does DSDT do ?
Do you have DSDT of this model?

No Body ?!!!!!

let's me guess you have to set graphic enabler to "No" then you can boot in to ML

and when you can get in to ML you have to set frame buffer

go to folder Extra > org.chameleon.Boot.plist

use this flag <key>AtiConfig</key>
<string>Bulrushes</string>
<key>AtiPorts</key>
<string>4</string>

or

<key>AtiConfig</key>
<string>Duckweed</string>
<key>AtiPorts</key>
<string>4</string>

then you can switch graphic enabler to "Yes"

done...

Hi

I tried both of them but it doesn't take any effect.
I didn't install chameleon on my hard disk.
I added the flags to USB/Extra/org.chameleon.Boot.plist
and it doesn't work.
