“We need a bios expert to help us study the differences between the pre version 44 bios and version 44, because that's where the problem with cpupm starts. I started digging, but I don't understand it well enough. Somebody who really knows b…”

“@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 peo…”

“@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 co…”

“I figure Airwalk probably deleted one of the RTC length sections since you only need one. For sound you just need the legacy kext, and then you need to either bin patch AppleHDA, or get the 10.6.2 rollback AppleHDA. If you google "perl Appl…”

“No, you need to have a modded DSDT, it just needs to be done right. If you're new to this stuff, I'd say use airwwalk's extra folder with his DSDT in it, but delete SleepEnabler. I think SleepEnabler was causing your original issue, and not…”

“@farski, are you going to try to get speedstep working? We need to identify a difference between bios versions e758_sz2z and e758_44 that is causing AppleCPUPM to panic, despite our setups meeting it's requirements otherwise. Not sure how t…”

“@neptunet, I suspect sleepenabler. Try booting without it. What board do you have and what bios version?”

“Alright, so can someone like airwalk667 or msinfo pleeease make a full acpidump from linux on your X58 SLI and post it? You've got to be using the same bios version (SZ2Z) and settings you're using in OS X. I want to get the whole thing and…”

“Just to update everyone a little bit. I've got the ALC892 on my E767 working with AppleHDA now using the new ALC8xxHDA kext from MacMan over at tonymacx86. First I tried to bin patch AppleHDA from 885 to 892, which made it load, but didn't …”

“I've been looking into it more. I'm wondering if I replaced the CPU microcode in bios version 77 from EVGA with the microcode from a Gigabyte X58 board's bios if that would fix it, but I'm not sure if that's really the problem. This is a co…”

“You should make a note in the first post about speedstep not working on the X58 SLI3 or X58 FTW3, and how it only works on the other models if you use the bios version before version 44, which is of course SZ2Z. I changed my mind and haven'…”

“Great. Thanks for all the help guys. I'm giving up now and buying an ASUS or Gigabyte even though I don't like the design. At least it will work better.”

“Okay so I just want to check to confirm, is the panic that everyone else gets with bioses newer than SZ2Z when trying to load AppleIntelCPUPowerManagement at boot a type 13? Mine is, and I want to make sure everyone else is getting the same…”

“I just followed the guides for gigabyte boards. There's a basic one on tonymacx86, and then some more really detailed ones on insanelymac. I have a post a few posts back that has mine with some other things I'm using attached, so you can ta…”

“YES! Farski, I believe the FTW3 is going to be very similar to my SLI3. I have to use the same ethernet driver. For sound I have to use VoodooHDA because I have ALC892, which won't work with AppleHDA even if you patch it. I think the FTW3 h…”

“Cool, now we're talking. I'm away from my machine for today (Happy Thanksgiving everybody), and then I have piles of homework, but when I get time, I'm going to be going over this guide a few times. It has something in it about the legacy k…”

“@shakall, I'm pretty sure you can use the E757, and I bet if you don't use any bios version newer than S71H, you can use the folder these guys are passing around. @everyone, I've gotten maybe a little closer to getting speedstep on my E767.…”

“I haven't tried that because the pm panics well before the voodoo does, so I didn't think it was worth it. I posted on insanelymac's dsdt fixes for gigabyte boards thread with my dsdt, ssdts, and ioreg output to see if they have any ideas. …”

“Thanks msinfo. It didn't work though. I tried it both ways. VoodooHDA didn't like the dsdt you gave me, but it likes mine fine, probably because I removed my audio device from it since I have ALC892. I always have to delete AppleHDA though.”

“Here they are if you want to look. I guess I'll start researching mods for them now.”

“Poop, I just updated to 10.6.5, but it doesn't help my X58 SLI 3 use native PM. It still panics without null. I even tried msinfo's newest pack unaltered. I guess now I sell this board and try to track down the older X58 SLI LE that it repl…”

“Well, I think I'm gonna have to wait for 10.6.5 to try it again. I'm running a 950, so I would have the same problem as you, and I know I've always gotten a kp anytime I tried going native. If I can find a torrent of 10.6.4 from a 2010 mac …”

“Any updates as far as getting native powermanagement with newer bioses? I have the new SLI 3 botherboard, and there's no older bioses that don't support 6 and 8 core chips. Do you guys think 10.6.5 will fix this since the 2010 Mac Pros have…”

“Interesting. I added the SSDT files (I don't fully understand the concept behind them, I guess just more of the same as DSDT) and put in dropssdt=yes, and now my gpu clock is at level 2 (626Mhz for me since I have the 260 superclocked :)), …”

“Yeah looks just like my output but I have the 216 superclocked so some clocks are higher in mode 1 and 2, and it's definitely stuck on mode 0. I ran some stress tests and it didn't budge past 300Mhz. Is your DSDT just like the one on page 2…”

“I dunno, I can't find a GFX string for it, and almost everyone else I've read who're using the GTX 260 are using GraphicsEnabler and it works perfect. That's what I used before on my old motherboard and it said x16. I ran nvclock and it say…”

“I reset my bios and it still says x8. There's only one bios for the SLI 3, and thats 74 I believe. I've got C2RC5 as the bootloader and graphicsenabler=yes (no strings or anything) I'm not using the DSDT from page 24, but I suppose I'll giv…”

“Yeah I tried taking out the firewire card and it's still reporting as x8. I had the same card in my old EP45-DS3L using GraphicsEnabler=yes and it showed as x16 on there. Maybe I need to reset my bios?”

“I'm having one other problem: System Profiler is reporting my graphics as x8. I only have one card (EVGA GTX 260) and it's in the first slot, although I do have a firewire card in the third full length slot.”

“Actually, I just got it working with voodoohda 2.56. I had tried 2.60 or 2.61 (forget which, whichever one is in MultiBeast) and it didn't work at all. It made one of the SMC kexts KP on boot. Anyway I'm pretty happy with 2.56. Sound in and…”

“I just bought the new EVGA X58 SLI 3, so I guess I'm screwed on native power management for now because it has 6 core support in the first bios. Should I try using one of the older bioses from one of the other boards? If someone got the pow…”

“One guy told me that if you take SleepEnabler out of /E/E, and then wait until after you boot and log in to load it manually, it will provide sleep functionality without causing a panic, and you can do 64 bit and NullCPUPM. I haven't tried …”

“With the P6X58D-E, you ought to be able to run without NullCPUPM or SleepEnabler if you did your DSDT right. I believe that's one of the ASUS boards that works. Should be a guide around somewhere like insanelymac.com. Then you can 64 bit an…”

“@mm2311, can you boot without nullcpupm?”

“Just get the tonymacx86 iboot cd.”
