With a patched DSDT you dont need all this kexts (I use just FakeSMC) and your CPU will dont run too hot, I use a Noctua cooler (air cooler) and my CPU even overclocked does not reach the 50 degrees in the brasilian summer. Here my config: ASUS P6TExternal Temperature 15 degrees   ps.: sorry about the bad english Last edited by vultu; 06-03-2010 at 02:31 PM.

Im sorry but I dont speak english well enough to teach someone. I could try to give you some tips where you need to put the code, but before that you need to have access to your DSDT. You can get your DSDT with the program DSDTSE (http://www.osx86.es/Archivos/DSDTSE.zip) choose the option Extract DSDT and save the file in some folder. You need this program iASL (I attached to this msg) to compile the DSDT.DSL file. Sintax to Compile (open the terminal and go to folder that you save the iASL file) Code:
./iasl -f /path_to_file/filename.dsl 02. HPET FIXStart with this after you have a DSDT working if you want you could try other things, but I prefer change the minimum in my original DSDT.

It's late and I'm about to crash, but I just had to share that I finally got audio to work.
I took Joeboxer's advice and used VoodooHDA from Multibeast. The newest experimental version (0.2.61) worked for me, but it doesn't look like optical out is activated. Have any of the other solutions (AppleHDA, DSDT, etc) made the optical out (toslink) work for anyone?

About to take the DSDT plunge...
Quote:
In the guide, though, you don't mention LegacyHDA at all. I've downloaded your modified version from page 3 of this thread and plan to use it with my reinstall. When would you suggest is the best time to copy LegacyHDA over? Just before multibeast, so the caches get rebuilt with it? Also, LegacyHDA goes in /E/E, right? Do I also have to delete all audio codecs from /S/L/E? With your rig now, sleep is your only obstacle, right? Have you been able to upgrade to 10.6.4 without hiccups? Also, have you enabled QuartzGL? Have you (or anyone else, for that matter) been able to OC with speed-stepping engaged? I'd read that can cause stability issues. Sorry for all the questions, and thanks again for all the help! and, just for the record, my rig is as follows: ASRock X58 Extreme i7 920 ZALMAN CNPS9900ALED Heatsink 6GB OCZ Gold (3 x 2GB) DDR3 1600 150 GB WD Raptor X 10,000 RPM hdd (for osx) 4 TB Scratch (2x2TB Hitachi hdds in RAID 0) Antec Quattro 850w PSU BFG GeForce 8800 GTS 640 MB

Yup! Evereything else works. I upgraded to 10.6.4 without issues. I've heard that QuartzGL (=Quartz 2D Extreme) is pretty much useless, since all it does is take a little bit of load off the CPU, at the cost of some artifacts. Since I have an i7 I don't think a little bit of 2D rendering will affect performance much  . I'll look into this thou.I have tried overclocking with speedstep, and it works (somewhat). The big problem is (I think) that, altho the multipliers are changed ok (ie. with 200 bclk speedstep 1= 200*16, 2=200*17 (maybe 16.5 or something), 10=22*200=4.4GHz=KP  ). So the problem is two things:
. Work's fine for default clock, but I've ruled out OC with it, especially now that it's summer down here  .

Gotcha on the overclocking.
I finally got around to giving the guide a shot today but didn't even get into OSX installation. KP'ed while trying to boot the SL dvd. >_< Were you able to just use the iBoot Supported bootcd, or did you have to change it before burning?

Starting down the DSDT path...
Ah. Would you mind sharing the new changes?
 So, even after playing around with every BIOS setting, I still wasn't able to boot iBoot. I played around with EmpireEFI, newer versions of myHack, and others, but I couldn't get anything to boot like I had with myhack 1.0 final back in the spring. My system currently works, but I'm wanting to make the full switch to DSDT hacks for optimization. As a side bonus, once I get the DSDT tweaked I should be able to actually boot off of something other than my hdd. I've tried for months to work with DSDTSE, but I was always getting the NilObjectException error. Finally, after messing with install locations to no end, I was able to install it to a myHack thumbdrive and actually access extract the table. In the guide you say you must be booted with iBoot for DSDTSE to work. Is this just a way to get around the NilObjectException error, or is there something else I'm missing? At this point, I've done the Ubuntu liveCD boot and have gotten past the changing of Scope(_PR). A couple of notes: 1. For anyone not familiar with Ubuntu, it might be useful to note that additional repositories have to be enabled for apt-get to install acpidump and iasl. 2. The part of checking if _PSD coincides with ist.dsl and if the "Package (0x04)" in _CST are in cst.dsl is stopping me because I don't know how precisely similar they have to be. Can you look over what I've done? I think the _PSD is alright... ist.aml (_PSD): Code:
Method (_PSD, 0, NotSerialized)
{
Return (Package (0x01)
{
Package (0x05)
{
0x05,
0x00,
0x00,
0xFE,
0x08
}
})
}
Code:
Name (_PSD, Package (0x05)
{
0x05,
Zero,
Zero,
0xFE,
0x08
})
cst.aml _CST / Package (0x04): Code:
Package (0x04)
{
ResourceTemplate ()
{
Register (SystemIO,
0x08, // Bit Width
0x00, // Bit Offset
0x0000000000000815, // Address
,)
},
0x03,
0x80,
0x015E
},
Package (0x04)
{
ResourceTemplate ()
{
Register (SystemIO,
0x08, // Bit Width
0x00, // Bit Offset
0x0000000000000816, // Address
,)
},
0x03,
0xA0,
0xC8
}
Code:
Package (0x04)
{
ResourceTemplate ()
{
Register (SystemIO,
0x08, // Bit Width
0x00, // Bit Offset
0x0000000000000815, // Address
,)
},
0x03,
0x80,
0x015E
}
So, sorry for this exhaustive post, but I'm kind of stuck. Is this because I generated the DSDT while booted with extra kexts, or is it just because my 2.5 BIOS is different than the BIOS you used when you wrote up the guide?
