[xxxslayeriiixxx]

UPDATED tutorial with new links. DSDT creation. added "Intel Speed step, turbo boost note". added quotations for better organization of steps.

For people wondering what the latest kext are after the "power management kext, speedstep fix" here it is. this is what i currently have in my kext folder. http://osx86.co/f57/guide-evga-x58-s...post51321.html

If anybody wants me to add any useful links in the first post just message me or tell me here in the thread

xxxslayeriiixxx,

i have evga x58 classified too but the 759 model, although my system is up and running im wanting to know if your dsdt would work on my mobo too im using bios 74, is there anything i would need to change in smbios like UUID etc...

im running 980x i7 @ 4.2
kingston hyper x 2000 mem 6gb
evga classified 759 mobo
Ati HD5970 x 2 crossfire x

thanks

Wow, very nice setup - congrats! If I m not mistaken you've got six core cpu, right? If so this would be an interesting test to see if you are going to get native power/turbo running with newer than we are all using BIOS. At a minimum I would expect that you need to modify CPU section for six/12 core (it is four/8 right now) and generate your own ssdt files.

PS You might be able to get away with auto-generated ssdt tables if you are using RC5

i would suggest to create your own DSDT.aml, but you could always try. also change your smbios.plist according to your hardware specifications like RAM, the mac model you want, etc...

@msinfo_us and fq360, I would also like to see if native pm works with the newer bios version and the 6 core chip. I've switched to an ASUS P6T WS for now, but my EVGA E767 still hasn't sold on craigslist. It might also be interesting to compare a raw dsdt dump with a 6 core cpu vs one from 4 core cpu on the same board and bios version and see if anything is different that might be causing the issue. Then perhaps the dsdt could be modded to make native pm work on the 4 core as well using a newer bios version, but I have my doubts.

Has anyone gotten cpu temps under os x?

Hi Guys!
Im running Vanilla 10.6.6 thanks to your epic guide but there are a few problems, so I'll start with a spec-out:

i7-980X
EVGA E760 X58 (BIOS 77 - Latest - Supports up to 16 Core CPUs)
2x ATI HD5870's XFire
Corsair Dominator GT (3x2GB)
2x Vertex 2 120GB
Samsung SpinPoint F1 1TB

So the problems began upon the update from 10.6.3 to 10.6.6 via the combo updater:

10.6.3 booted perfectly in 64-bit mode, where as now with 10.6.6 installed I HAVE to go in via safe mode otherwise I get a light blue screen.

Spotlight has randomly stopped working (may just be as I am in safe mode)

Native Power Management will not seem to work with my CPU - I have patched my DSDT with what I believe is all the patches needed for this to work except for SpeedStep and P+C States - I don't think this is required for NPM?

iAtkos S3 V2 works perfectly in 64-bit mode so I am at a loss as to what could be causing my problem.

Okay so main things I want to get working:

64-bit NON-Safe mode
NPM
SpeedStep + Sleep would be great too although there is a severe lack of 980X DSDT's patched for this CPU around.

Any help would be greatly appreciated!
Thanks!
Myles

UPDATE:
Just did some tinkering and aparrently my kernel AND extensions are running in 64-bit mode!
I ran GeekBench and got a pitiful score for the spec: 13676 in 64-bit mode and 12500 in 32-bit mode

In system profiler it shows all 6 cores and 6GB RAM however :/

Is there something wrong for me to get such a low score?

[msinfo_us]

Couple questions:
1. Are you running Chameleon RC5? What version? Do you have CStates enabled and PStates disabled? Do you use DropSSDT=yes and your own SSDT's or DropSSDT=No?
2. What MAC model are you using? You might want to try few diff matching your system or create your own model to match exactly with your HW (I am using 11,1 and it had major impact on my geekbench. With i920 I get 14780 ... so you should certainly see more on your system. PS NPM enables turbo so this could also impact your score.

I have no experience with iAtkos S3 V2 and used vanila DVD to install, so may be who does have knowledge can comment.

Hi msinfo,
1) (a) Yeah Chameleon RC5 via the installer rev 693
(b) CStates are enabled and PStates are as default (I assume this means disabled)
(c) I don't use either so I'm imagining DropSSDT=No is default
2) (a) I'm using a MacBook Pro6,1 - 2.66GHz (Mid 2010)
(b) To create the actual SL install though I just use iAtkos on the target machine
(c) I'm using iMac11,1 as well and have tried Mac Pro 4,1 neither with an advantage over the other
(d) NPM most definitely isn't working on my machine as I get KP's as soon as I drop NullCPUPowerManagement.kext so my guess is that this is irrelevant to my score?

It's not the score I'm worried about though it's the lack of being able to boot without safe mode enabled, At the moment I can boot perfectly in safe mode with 64-bit extensions and kernel but flat-out refuses to boot without -x enabled, It stops just on a light blue screen - in verbose mode it is the point where it says something about CPUPowerManagement...

[banini_jeque]

@Mutant, I want to know more about your kernel panic when you drop NullCPUPM, specifically if it's a type 13. If you could post a pic of it that would be great. I think everyone else is mostly using DropSSDT=Yes. Also I don't think most people on this thread are using any distros like iAtkos. I have a suspicion that caused your video issue when you went to 10.6.6, but I don't know, so my suspicion probably isn't worth much.
