Anyways, I'll send you my DSDT for this BIOS version, it should work fine since I have no CPU/GPU injection and we have the same amount of memory. Also, I'll send the kexts (which you can build an mkext from if you wan't, for faster booting) & plists.
You'll have to give me a while to cook it up since two days ago I tried flashing my GPU and and it went wrong... needless to say I'm waiting for someone to lone me a GPU so I can reflash. But I'll put my HDD in an external enclosure and copy those files.
BTW: AWSOME CASE. I hate mine . Isn't 1000W (even if it's peak) kind of overkill for that rig?.

EDIT: here, just unzip this on your root folder (aka "Macintosh HD" or "/"), and install the latest chaemaleon from multibeast or use this installer: http://www.insanelymac.com/forum/ind...=post&id=87336 (you'll have to log in to download).
MAKE SURE YOU USE THE INSTALLER/MULTIBEAST FIRST! AND ONLY SELECT CHAEMALEON, NO KEXTS OR ANYTHING ELSE. IF THE INSTALLER CREATES AN EXTRA FOLDER ON YOUR HD, DELETE IT AND THEN UNZIP MY OWN. I did this all in caps, since it's essential: otherwise the installer will overwrite my Extra folder with it's own.

Also make sure you have your BIOS settings right, and see the note on OCing (below post).

Sorry for never responding.
Sleep: I still haven't gotten it to work, thou I think it's not DSDT related (I tried using an ASUS DSDT and it worked, except for sleep...)
BIOS settings: http://www.youtube.com/watch?v=zcmHdQxjANY I made the vid using some historic BIOS version, check if the settings are still the same.

You can now OC without issues using "GenerateCStates=Yes" and ""GeneratePStates=Yes" in DSDT. For this, you need to NOT have CPU info in your DSDT.

Thanks for responding so quickly, Adrian

Sorry to hear about the failed GPU flash. Yeah, the PSU is overkill but it was highly rated AND was on sale at Newegg. Oh and I didn't mention that I have my 930 overclocked to 3.6GHz with a Zalman cooler (for some reason it's showing a bit faster at 3.78 under OS X).

I've attached a screenshot of the KEXTs I already have loaded. I'm sure from what you've been posting I can weed those down to just a couple. Do I still need to install the latest Chameleon if I already have a boot loader? As to the DSDT, I'm wondering if it will help with one issue that's been bugging me since I first built this. Whenever I go to reboot, instead of the PSU staying on and just the MB resetting, it will shut the power off to the PSU and then turn back on but when it does this, the MB won't post - no codes at all. I have to power it off for a few minutes and then hit the power switch. My case has plenty of fans and the CPU registers at a max temp in the 60s (C) under load. In the PSU manual, it says that it has current/voltage (over & under)/power and short circuit protection. I'm wondering if the PSU is taking the powering off as an undervoltage situation and locking it until it releases it after a few minutes. It DOES otherwise softboot if I clear the BIOS to default settings. Real head-scratcher.

Thanks again

I don't know why I don't get email alerts of replies... I'm subbed

Well, if you use the files I linked (which include the latest chameleon -needed for P and C states, the minimum necessary kexts, DSDT and plists), you can get down to just fakesmc an audio and a network kext (unless you'r using an ATI GPU, in that case you probably need another ATI kext, I have nvidia so I'm unfamiliar with ATI under OSX). My package contains these kexts and hardware monitoring kexts, to get fan speed, voltages, temps, etc. Please tell me if you'r using ATI as the kext required for GPU monitoring differs.

As for the reboot issue: it boils down to hard vs soft: if it's a software issue (ie, related to the way OS X reboots) it'll probably be fixed. If it's hardware, I doubt it.
I have a similar issue: bclk>160 and I can't sleep in windows and reboots power off completely (thou it does turn itself back on). If it's under 160, evereything work's normally.

I hope I helped

Yeah, funny how you can feel snubbed by not getting alerts. Just as long as it isn't a friend trying to get ahold of you for something important.

So I held my breath and installed your download. The DSDT seems to start up fine if a bit slow. Lots of additional temperature sensors in iStat widget AND the CPU is running (or reading) a lot cooler with the MacPro 5,1 ID. I also reset the BIOS to the settings in your video (Not sure of the C State enabled and then setting to C6. I always thought that was for non-Core Intel CPUs). Also, I have an MSI GTS-250 1GB GDDR5 so no worries about ATI kexts. I DO have a couple of IDE drives installed but don't really need for OS X as they have an old install of XP Pro but I haven't got all the data files moved to my Win 7 drive. Sound finally works without resorting to running Voodoo kexts but wish the new sound setup didn't give off a loud pop over my speakers when loading. I'll move the other unnecessary kexts out of the /Extra/Extensions folder and see how that goes next.

I still have the hard reboot problem - in both OS X AND Win 7 so I want to think it's BIOS related. I've been unemployed for a while otherwise I'd go and get a new PSU to try and see if that's the issue. The installed Rosewill PSU works great other than having that one bugaboo.

Thanks again for your help. I still don't have the faintest idea how to edit a DSDT but grateful that yours seems to do the trick without any tweaks.

subbed= subscribed

Yeah, remove other kexts and create an mkext (I can do it for you, but you should learn how). The booting is slow because of all the different kexts for temp monitoring, etc. If you use an mkext (a package of kexts), it'll load much faster.
I don't get any audio pops...
If it happens in Win7 too, it's hardware related (or BIOS, as you say, but I doubt it). Try booting @stock speeds, and see what happens.
DSDT: it's "a document describing your PC" (far from the exact definition, but easy to understand). So it says: I have 2 cores, such and such Audio chip, this GPU, etc, etc. The thing is, PC makers don't follow specifications... why? because the document needs to be compiled ("read") by a compiler, and there are two, the intel one (follows specs, apple like) and the microsoft one (doesn't follow specs). Additionally, apple uses their own way of DSDT, ie, some things that are in spec are not to OS X's liking. So we have to edit this document, according to what apple/specifications want. Editing it is another story... Download DSDT SE and "extract DSDT" to see your currently loaded one (if you want to see the plain DSDT, boot with iBoot or something, otherwise you'll get my edited one ).

On another note: what are your memory voltage readings like? Mine are way off!

Hi everybody here, someone had try Lion on that system?
Best!

Successfully installed Lion and just upgraded to 10.7.2 on mine.

Great! Happy for you.
For me I'm testing a new Lion iatkos 10.7.1 on a new harddrive.
The problem is when I update to 10.7.2. No sound.
Even if i use the old kext, still no sound.

Can you please explain how you get audio for our alc890 ?
Thanks!

I reply to myself, maybe some other is interested to know..

I finally have sound with a simple solution: I take back (from a snow leopard installation) 2 kext:
applehda and voodoohda. Run kext utility and.. sound!

I have tried that before, but I was using the extra folder, so do not do that. Put the 2 kext on system/library/extension.

Concluding, now I have 10.7.2 full working, sound and sleep too!!!

Hope to help some one.. bye to all ;o)
