Just for an experiment I just tried to boot with a DSDT from an X58A-UD3R. First I tried with NullCPUPM and the SATA ports weren't working right, so I got waiting for root device errors and stuff. Then I tried with -allowAppleCPUPM and I still got the type 13 panic. I don't know if that tells us anything or not.

So, an update on my X58 SLI3.

I got sound working with AppleHDA instead of VoodooHDA using the new ALC8xxHDA.kext from MacMan, which works on ALC892.

I've been playing with acpiexec and a full dump from ubuntu, but I don't really understand it. I figured out executing commands in the different tables, but I don't know which tables I should be testing specifically, nor what sort of errors or feedback to expect. I also downloaded a full dump from a MacPro4,1, but again, it's pretty much useless to me until I learn more about how it's all supposed to work.

That's all. Seriously considering the ASUS P6T6 Revolution or P6T WS Pro. If Gigabyte redoes the X58 series like they're doing those all black upcoming P67 boards though, then EVGA can kiss my white @ß.

Thanks, and those are some good numbers!
Any recommendations on the settings to be used for stable overclocking?

Your using a 5520 chipset so why not find a supermicro equivalent? there are people out there running on 2 cpus I have a SUPERMICRO X8DAL-i 5500 series so cant help with that...

Response from Tutor1;

Again, thank you for your insights. My system was at first hobbled like almost everyone else's until I came across your philospy that less is more. I reconfigured my system to be almost exactly like you recommend in post no. 1, except (1) I use the latest bios that allows me to set the un-core frequency to the highest setting, given the memory that I use, (2) I use Profile 1 for my ram chips - which sets the ram voltage to 1.65 and the VVT voltage to 1.4 and (3) that for every step below a processor clock ratio of 25 that I set I get an extra increase in the turbo ratio. Thus, by stepping down my 5680's from a CPU clock ratio of 25 to 20, I get a turbo ratio of 666677 from them. This allows me to use much less voltage for over clocking because my 3.33 GHz chips run at about 2.67 GHz most of the time, except when I put them under load using Cinema 4d , Vue xStream, or Maya. Then with my BCLK set to 170, I get turbo extremes in excess of 4.4 GHz (26x170=4420 and 27x170=4590).

Having 20 fans (including one over each of the two banks of 2000 MHz DDR3 ram chips, one directed at each of the two heat sinks near the processors and one over the NB fan) doesn't hurt either. Also, I set my bios controlled fans to run at 60% minimum and at 100% at 60 degrees centigrade. Having all of these fans keeps my system temps very cool. I call my computer a "FrankHacWinTosh" because just like Dr. Frankenstein, I designed my case based on my perceived needs with parts from other computers (horror recycling), including to cool certain components that would be stressed out from over clocking. Actually, my Dremel tools got much hotter when I was making the case than my system ever gets. I gutted a massive case that a good friend in Atlanta made for me in 1992 to house a used Macintosh IIfx mobo and used a hacksaw (ala "Hac") to cut parts from even older cases to meet my design goals. In case you'd like to know, I didn't mind retiring that 18 year old Macintosh IIfx, with that "wicked fast" 40 MHz 68030 processor.

Thus, I credit (1) the physical environment of the system as providing the temp control headroom necessary for keeping my system running stable 24/7 and not making me a servant of the power company and (2) you for providing an insight that, although is contrary to the conventional wisdom, is nevertheless the most effective path to follow - less is more especially when it comes to the base CPU clock ratio and more derives from increasing the turbo ratio. Thanks d00d.

but you could help me candykane :)

I have the Asus Z8NA-D6 with the 5500 chipset - everything working except sleep. could you send me your dsdt to compare?

@d00d - great to see that someone is working seriously with this board. I was thinking about buying an SR-2 almost 6 months ago. there was a guy in some forums that offered me to buy a "special bootloader" only made for this board - otherwise there wouldn´t be any chance to boot it....hahahaaa - so good that I was patient enough

mine 5500 is loading the AppleTyMCEDriver.kext with MacPro 4,1 - I know the sr-2 has the 5520 chipset, but could there be any helpful information for your work ?

Thanks for starting this thread d00d.

Just wanted to point out that MaLd0n's autopatcher has the HDEF edits and shutdown edits included in it for A50. Sleep still does not work with MaLd0n's DSDT, but that gets us awfully close to a vanilla experience!

I am having problems getting sleep to work with d00d's edited DSDT and NullCPUPowerManagement.kext+SleepEnabler installed.

The monitor blanks out when I select sleep/press the power button, but the fans never stop spinning and the system never really shuts down.

I set the BIOS settings as instructed and have checked and un-checked the settings in Energy Saver to see if that makes any difference.

Anyone have any idea what I am doing wrong?

The kexts I am using are:
10.6.2 Apple HDA
HDA Enabler
EvoReboot
NCPM.kext
SleepEnabler
FakeSMC
IOAHCIBlockStorage

It works for me in 64bit using NullCPUPowerManagement.kext, SleepEnabler.kext from http://code.google.c...ues/detail?id=5 comment 24, and my DSDT_SR2-2 with MaLd0n's shutdown fix added.
I'm not sure the shutdown fix helps because I didn't test without it.
You shouldn't need EvoReboot.kext if you are using the C2RC5 bootloader.

Thanks! I tried that SleepEnabler, but still have problems.

I will set the BIOS back to default and then make only the prescribed changes and see if that helps.

Also, I finally bothered to hook speakers up and there is no audio, even though the audio symbol appears in the top right, AppleHDA.kext is running, and all the outputs/inputs appear in System Preferences->Audio.

I tried with DSDT edits, then with HDAEnabler, but both have the same results.

Has anyone gotten the onboard audio to work with any method?

Try SleepEnabler.kext without NullCPUPowerManagement.kext, sleep also works for me this way.

Update;
Sleep works without SleepEnabler.kext too.
Looks like MaLd0n's shutdown fix fixes sleep as well.

Update;
MaLd0n's shutdown fix doesn't fix sleep.
Sleep was already working.

Yep, working over here as well! Somewhere in the BIOS I must have changed one too many values. Sleep/wake is working normally. Thanks for noticing d00d!

The only thing left is the onboard ethernet, onboard audio, and getting TyMCEDriver to not hang. The audio can be made to show up as loaded with standard ALC889 kexts/DSDT edits, but it still does not actually produce any audio.

Do you have any idea why that is d00d? Any guides that I might be able to read to attempt a fix?

The ethernet looks like it would take an entire port job, a la Lnx2Mac, which seems a bit much since no one but EVGA uses this chip.

I assume I can just modify a Disabler.kext to get TymCEDriver to not load, which seems better than just deleting it and then forgetting to do so again after I update to 10.6.7. Looking into that now.

edit:
There does still seem to be a problem with sleep above ~166BCLK. When I am overclocking past 166BCLk the system sleeps, then wakes up, but never posts the video again.

edit2:
god, sleep sometimes works and sometimes does not regardless of the BCLK. I also got a few KPs on bootup. I am starting to think I have a hardware problem. Here goes some more tests =/

Mine sleeps at 180 BCLK, but I haven't tested higher.
This depends on your overclock voltages, they must be stable.

I couldn't get the on board audio to show in Sound with MaLd0n's DSDT HDEF section, so I had to use the HDAEnabler.kext from ALC889_AppleHDA_199f12.zip.

The original AppleHDA needed to be binary patched for the ALC889;
% sudo -s
Password:
# sudo perl -pi -e 's|\x85\x08\xec\x10|\x89\x08\xec\x10|g' /System/Library/Extensions/AppleHDA.kext/Contents/MacOS/AppleHDA

The ALC889.kext from Legacy_ALCxxx.zip was also used.
This can also be done by editing the Info.plist files in the AppleHDAHardwareConfigDriver.kext and AppleHDAPlatformDriver.kext PlugIns, or using the AppleHDA.kext that includes these edits from ALC889_AppleHDA_199f12.zip.

However, none of the outputs work.

I got these kexts from tmongkol's topic;

I got AppleTyMCEDriver.kext to load when I changed from triple channel mode (all 12 memory slots full) to dual channel mode (8 memory slots full, with slots 5 and 6 empty in each bank).
So I'm down from 24GB memory to 16GB, and if I want more memory I'll have to buy 4GB DIMMs.

Any recommendations on the settings to be used for stable overclocking?



d00d, I finally figured out that I had to take two tests to post any more because I am a newbie. Here are the picts. But first - a test for other newbie visitors.

If you read d00d's posts very carefully, you'll see that he teaches us that less is more. Using conventional wisdom, is a system with lower clocked GHz chips faster than a system with the same number of chips and cores, but higher clocked?

In other words, which of the following 12 core systems is fastest at running OSX benchmarks under Geekbench2 and Cinebench 11.5:

1) a 2.930 GHz system,

2) a 2.550 GHz system,

3) a 2.325 GHz system or

4) a 2.230 GHz system?

I know that there are some "depends." But if you've got d00d's messages correct, then you'll be on the right track for overclocking (I really mean "underclocking") Westmere's and Nehalem's. If you want a faster mac, then underclock it after you've done as d00d suggests in post #1. If you want an ever faster mac, then underclock it some more. Serious underclockers seek a turbo boost payday. My present 24/7 underclocking achievement is a 12 core 2.230 system that pays me back with a turbo boost ratio of CCCCDD (i.e., 12-12-12-12, 13-13). "So what!", you may say. Since my two processors are the xeon x5680 that run natively at 3.33 GHz and at a x27 top [and most importantly to remember - constant] ratio, whatever number my CPU frequency is (such as 160) gets multiplied by 27 to determine my maximum turbo boost speed. At a CPU frequency of 160, my maximum turbo boost speed is 4.320 GHz (160*27). I can lower the CPU Multiplier setting from its stock maximum of 25 [on my x5680s] (the other 2 digits adding to 27 are there for standard turbo boost) to 13 or 17 or 15 or even 14 [or any other number less than 24 but greater than 12]. The order in which I've listed the CPU multipliers in the previous sentence are starting with the best for my system. Odd numbers yield best results - at least on my system; so your mileage may vary. The maximum turbo boost speed (4.320 GHz) remains the same so long as the CPU frequency (BCLK) setting isn't changed. But as I take that CPU Multiplier lower (dousing a little more BCLK on it as I go lower), my system remains cool and I can use less Vcore. This increases the chances that I'll get all of the available turbo boost when needed. Overall, it also does not put as much stress on my CPUs all of the time. C-states, T-states and all other energy and power management/savers are activated. CPU core temps range from 26 to 33 degrees C while just word processing or surfing this forum to 55 to 64 degrees C when rendering in Cinema 4d. This is how to speed up your system, while prolonging its life and holding on a little longer to that cash your power company wishes you would spend for energy.

Show me a faster OSX system (those i7-2600/2400 scores that appear and are routinely removed from and by Geekbench and my posted Geekbench scores, such as the 37837, 37393, etc. don't count) and you will have shown yourself someone else who is a follower of d00d's teachings. Check out the picts below for proof of the truth of d00d's philosophy. To truly get the point, check out the picts in reverse order. On the ostensibly slowest setting, the Geekbench2 score is 33% faster and the Cinebench 11.5 score is 39% faster than on a 2.93 GHz 12-core system. If you use Cinema 4d, a 39% speedup in rendering performance is nothing to sneeze at. Again, thanks d00d for graciously sharing your advice and helping me to get internal audio working. You've truly earned the title "InsanelyMac Sage".

Geekbench 2.1.12 for Windows x86 (64-bit) yields a score of 27,775 and Cinebench 11.5 yields scores of 76 fps and 20.49 for the xCPU. So you see that following d00d's teachings also makes for a not too shabby Windows dual boot system.

Wow! Great. I never would have thought of trying that. Luckily I have all 4GB DIMMs and only 6 ATM!. Thanks for your continuous fiddling with this board :hysterical:

Is there another Cal Aggie in the house? Do you have an EVGA SR-2? It's a great mobo. However, the same thing can be done with i7-920 & i7-980X systems. I've done it using d00d's quidelines published elsewhere on this forum.

Do you have sleep problems in dual channel mode?
Mine wouldn't wake from sleep, so I went back to triple channel mode and the AppleTyMCEDriver disabler.

Another problem is that the Parallels (5 and 6) and VMware Fusion (2 and 3 in both 32 and 64bit boot) applications use 100% CPU (or 200% when configured for two CPUs) and lock up after the EVGA wakes from sleep.
This happens after an image is started or resumed, and wasn't an issue with the Gigabyte.

1) a 2.930 GHz system,

2) a 2.550 GHz system,

3) a 2.325 GHz system or

4) a 2.230 GHz system?

I know that there are some "depends." But if you've got d00d's messages correct, then you'll be on the right track for overclocking (I really mean "underclocking") Westmere's and Nehalem's. If you want a faster mac, then underclock it after you've done as d00d suggests in post #1. If you want an ever faster mac, then underclock it some more. Serious underclockers seek a turbo boost payday. My present 24/7 underclocking achievement is a 12 core 2.230 system that pays me back with a turbo boost ratio of CCCCDD (i.e., 12-12-12-12, 13-13). "So what!", you may say. Since my two processors are the xeon x5680 that run natively at 3.33 GHz and at a x27 top [and most importantly to remember - constant] ratio, whatever number my CPU frequency is (such as 160) gets multiplied by 27 to determine my maximum turbo boost speed. At a CPU frequency of 160, my maximum turbo boost speed is 4.320 GHz (160*27). I can lower the CPU Multiplier setting from its stock maximum of 25 [on my x5680s] (the other 2 digits adding to 27 are there for standard turbo boost) to 13 or 17 or 15 or even 14 [or any other number less than 24 but greater than 12]. The order in which I've listed the CPU multipliers in the previous sentence are starting with the best for my system. Odd numbers yield best results - at least on my system; so your mileage may vary. The maximum turbo boost speed (4.320 GHz) remains the same so long as the CPU frequency (BCLK) setting isn't changed. But as I take that CPU Multiplier lower (dousing a little more BCLK on it as I go lower), my system remains cool and I can use less Vcore. This increases the chances that I'll get all of the available turbo boost when needed. Overall, it also does not put as much stress on my CPUs all of the time. C-states, T-states and all other energy and power management/savers are activated. CPU core temps range from 26 to 33 degrees C while just word processing or surfing this forum to 55 to 64 degrees C when rendering in Cinema 4d. This is how to speed up your system, while prolonging its life and holding on a little longer to that cash your power company wishes you would spend for energy.

Show me a faster OSX system (those i7-2600/2400 scores that appear and are routinely removed from and by Geekbench and my posted Geekbench scores, such as the 37837, 37393, etc. don't count) and you will have shown yourself someone else who is a follower of d00d's teachings. Check out the picts below for proof of the truth of d00d's philosophy. To truly get the point, check out the picts in reverse order. On the ostensibly slowest setting, the Geekbench2 score is 33% faster and the Cinebench 11.5 score is 39% faster than on a 2.93 GHz 12-core system. If you use Cinema 4d, a 39% speedup in rendering performance is nothing to sneeze at. Again, thanks d00d for graciously sharing your advice and helping me to get internal audio working. You've truly earned the title "InsanelyMac Sage".

P.S. For you dual booters, this is how an underclocked 2.534 GHz setting (2.33 GHz juiced up thru E-Leet with additional BCLK and voltage) stacks up in Windows 7 on Wprime:

Geekbench 2.1.12 for Windows x86 (64-bit) yields a score of 27,775 and Cinebench 11.5 yields scores of 76 fps and 20.49 for the xCPU. So you see that following d00d's teachings also makes for a not too shabby Windows dual boot system.

Is there another Cal Aggie in the house? Do you have an EVGA SR-2? It's a great mobo. However, the same thing can be done with i7-920 & i7-980X systems. I've done it using d00d's quidelines published elsewhere on this forum.

Thanks for this, I have my system plugged into a UPS that reads out wattage, so I'll be testing if this will bring down the current ~255 W.
