Asus P7P55D Working with 3.8Ghz OC

System in signature. Used TonyMac iBootCD Test2 (Nvidia)
Installed multibeast and 10.6.2 combo update
Voodoohda, vanilla 10.6.2, DSDT, etc

DSDT was obtained from here:http://www.tonymacx86.com/viewtopic.php?f=14&t=13

I've gotten everything working great with my setup, except my busratio seems to be stuck at 20, even though the BIOS has it at 21. That is part of the Intel turbo thing, but does it rely on speedstep? Is there something I am doing wrong, or does Apple's vanilla kernel lock it at default clock?

Edit: Still fighting with QE/CI but not having much luck..

Take a look at your /Extra/com.apple.boot.plist- make sure there's not a busratiio=20 there. Also, if you're booting from that CD, I've added busratio=20 for the i3/i5 dual core systems. It will lock your cpu at that busratio, allowing those systems to boot the installer. Remove that kernel flag, and you'll be good to go.

Well, I decided to nuke it and start over.. and this time did the following:

Boot with nvidia test2 disc
install OSX
update to 10.6.2
before rebooting and after 10.6.2 used Multibeast to install ONLY:
Easybeast 10.6.2
VoodooHDA
I think Standard plist with graphicsenabler=yes, 32bit
Realtec NIC driver
all the extra kexts except PS/2
NOTHING under the DSDT or Graphics
Kext Utility (in case I need it)

After reboot all was working, with QE/CI, LAN, sound.
The busratio part I don't know what to do with. My plist currently looks like this:

Even though it has no busratio in there, it still is running at x20 instead of x21. Windows sees it as x21 and shows 3999Mhz. If I'm stuck this way, I'm still happy.

I have not tried removing the arch=i386 to see if I still have QE/CI in 64bit. I was running 64bit last build and had no luck whatsoever with it, but that could be from all the tweaking and whatnot.
