Could we get more details on your setup?

 

EP45-UD3P 8 Gb RAM 8400GS as primary video card with a 7200GS as secondary. 2 Asus VW246H and an Acer X223W monitors. The primary video card handles 2 monitors, one on VGA and one on DVI. The 7200GS runs the Acer on VGA. As I said, this has been working great in 10.6.x until the update to 10.6.3.

results agree with mm67. Loaded straight to windows by pressing f12, got the same temp as before. Oddly enough, when i rebooted back into osx, my temps rose about 7 degrees from before (I was idling at around 45 OC'd to 3.33 in OSX, now idling on 52ish).

I get exactly same temperatures on OS X, Linux and Windows. You probably haven't got powermanagement working correctly if you are getting higher temps on OS X. You should add speedstepping to your dsdt or at least use NullCPUPowermanagement or VoodooPowerMini kexts. Kext solutions may cause you problems with future upgrades so the best thing you can do is to start studying how to fix your dsdt.

Are you seriously trying to claim that using Chameleon has something to do with how Windows reads cpu temperatures ??? Maybe you should run some tests with and without Chameleon and you will very quickly see that those things have nothing to do with each other.

 

That is correct as the bootlader we use would interact with the bootloader for windows. Also one thing to keep in mind, temps from BIOS are going to be different from within the OS as the OS will be putting a load on the system.

This thread is for us to share our experience with the hardware configuration:

Obviously, the case, the hard disk, and the memory don't have to be the same, but here they are for the sake of posterity:

 

The lifehacker guide including hardware config can be found here, and simplified even further through the addition of an automated script here.

 

Kudos to Adam Pash of lifehacker for putting this together, it's quite amazing to be able to do this so cheaply and simply!

 

If you've spent the money to get this exact configuration, it's probably a good idea to have a single place to discuss any problems that come up in the future. So share your experience here and hopefully this awesome hack pro setup will work flawlessy untill it's time for an upgrade!

 

[uPDATE]

There is an updated installer from stellarola:

http://stellarola.tumblr.com/post/23846198...-update-ud3p-v3

It should work for 10.6.2

 

I have almost the same setup and 10.6.3 run fine except, I cannot get my 2nd monitor which is touchscreen to work. I works on my macbook, and my mac pro at work. It also works fine when I boot up vista, but when I boot up OSX I cannot get the touch to work. (it's USB controlled BTW)

Any ideas?

Like I told you, do some testing and you will find out that the bootloader has nothing to do with temps.

FAKESMC which is built into the bootloader, translates hardware calls to the software. This is why there are reports of temps being so far off scale in some instances. But for the most part they are on par.

 

People! If your system is not melting or on fire its ok. The BIOS defaults are set to automatic and will manage any temps that rise.

Are you booting 32 or 64 bit? Because, I'm fairly sure that 7 series can't boot 64 bit natively.

Fakesmc is not built into bootloader and has nothing to do with how other operating systems see temps. If you don't believe me just go to Voodooprojects forum and ask the developers.

64, but as I said, this works fine in 10.6.2, I'm typing this on it now. I did the update to a backup USB drive. I do realize the restrictions for the 7200GS, but I believe that only applies if it is the primary video for that system.

You are getting the signal disappearing because the last stage of the bootloader is to change resolution of the graphics card, i.e. graphics driver loading. Do this...

 

Boot from your USB install drive with the v3 installer on it, if that works reinstall the bootloader from the v3 installer. Remember to delete the extras folder first.

 

Hi SBMac,

 

I booted from my flash drive, but unfortunately, the signal disappears again...

 

Do you have any other suggestions? If not, I guess I'm stuck on 10.6.2.

 

Thanks guys!

Do you have the V2 or V3 installer on your flash drive?

If you guys want your temps to report more accurately, and aren't afraid of breaking something else, just zip/move/remove the following kexts and reboot:

 

/System/Library/Extensions/AppleIntelCPUPowerManagement.kext

/System/Library/Extensions/AppleIntelCPUPowerManagementClient.kext

That does the same thing as installing NullCPUPowerManagement.kext, that file just disables those 2 vanilla kexts so you don't have to delete them. But both methods break sleep, to have sleep you must install SleepEnabler.kext which will give you problems when updating.

 

Neither method will improve accuracy of temperature reporting, they will just make cpu run cooler by allowing it to use lower multipliers while idling.

Not that I didn't expect it to, but it did lower my temps by 10 degrees. If I had the knowledge I would make an installer package for each release of OSX. Basically the only thing that needs changing between every release is sleepenabler.kext, which doesn't usually take to long to be released after an update. I don't know about you guys, but waiting an extra day or two to update for 10 degrees lower temps seems like a good deal to me. I'm sure we could get ahold of Stell to get the installer details. Any volunteers or ideas? But then again, I could just delete SleepEnabler.kext before every update, which would probably be a lot easier than creating a whole new installer package. Although, it has been discussed before about making our installs even better.

Yes, you now have P-states working and that will usually get you about 10 degrees if are you using stock cooler. If you fix powermanagement by fixing your dsdt then you will also have C-states working and will probably gain something 5 degrees more. That way you can also keep your installation in vanilla condition (no need to remove any kext files) and you won't need SleepEnabler.kext.
