CHUD tools

Hello guys,
My G5 Chirrips and it gets picked up by my studio equipment.
I've been told turning off napping will sort this.
Is there anything I should be aware of when turning of 'napping' ?
Cheers
Mike

Hi,
This is the way it was explained to me: Napping causes the CPU's to go to a low power mode between use, that means constant and sometimes rapid 'on, off' cycles.
"+Nap is one of 3 internal power saving modes of the CPU: nap, sleep, deep sleep.+
+Chirping is a heterodyne issue with the power supply inductors. It's usually there in most any switching power supply at varying degrees, just not usually in the frequency range of human hearing. It is triggered by large, instant power load swings+"
So turning off 'Nap' just keeps the CPU in the full on mode all the time, which is fine if you are constantly using the computer. Setting it to 'sleep' at dormant use intervals will take it out of the 'full on' mode and save some heat and electricity.
Regards,
Dave

AOL Install Fix using CHUD Tools

Hello,
For those of you who were asking about how to fix the AOL install problem on Intel Macs, here is a tip I found at macosxhints.com:
AOL seems to have a problem installing on multi-core Intel Macs. The installation hangs at "Installing Main Database." I found a successful workaround for this problem. Go to Apple's developer website and download the CHUD Tools. Once installed, there will be a Processor preference pane in System Preferences. Use this to turn off all but one Intel processor, then run the AOL installer. Once the installer finishes, turn the processors back on. Disabling CPUs solved install issues with other apps.

Holy cow, what a piece of junk installer. SERIOUSLY?!?! The AOL engineers never in their lives tested their application on a multi-CPU machine?
Seriously. How would anyone trust something so junky to their machine.

Download CHUD Tools then massive power failure

HELP, PLEASE!!!
I've had my MACs for about 6 years now and never had any real problems. Recently however I noticed the G4 starting running quite hot and loud so I decided to use CHUD tools to cool it down a bit. I downloaded the app and ran the 'previous CHUD versions' checker as instructed. As soon as I clicked on it the machine shut down and I've been unable to restart since. (I don't think it actualy launched and I didn't get as far as installing the actual tools app)
The power light has a solid white light on when depressed, but goes no further. I've investigated the cause quite thoroughly and read all the forums about the G4 PSU failure,PRAM reset,battery changing,CPU reseting etc. I've done all of those and have the +5v trivkle on pin 1 of 24 of the PSU.
I've also tried a different hard drive in the machine - trying to ascertain whether it is the CHUD tools causing the problem (software/hardware problem?)and it still won't power up. Therefore I think that it's just a crazy coincidence that I launched CHUD and then had this failure as the 'non-CHUD infected' drive should have enabled the machine to launch I think.
So I'm wondering, I think it has to be either the PSU or power switch itself. I have the 5v trickle as mentioned, but are there further tests I can do on a 24 pin supply to confirm its status please?
If not, Is there a way of testing the power switch on the front of the machine please?
THANKS VERY MUCH IN ADVANCE FOR ANY HELP!
regards
Dan

Even if by 'PRAM reset' you mean use of the PMU switch, you may not have hit upon the single most useful first approach to an MDD that fails to start up: resetting the MLB.
Switch off mains power at the wall or power-board. Open the door and ground yourself on the internal metalwork, Remove the PRAM battery. Unplug the mains cable at the Mac end. (This is Apple's recommendation, but I don't follow it because Australian GPOs—power outlets—are universally grounded three-pin sockets. If your GPO tests as reliably grounded, as well as switched, you don't need to do so, either.)
Wait at least 10min. Replug the mains cable into the Mac (if you separated it above), but do not yet switch on mains power. Ground yourself again. Restore the PRAM battery only if it shows above 3.3V in circuit. Otherwise, replace it with a new battery. Wait 20sec. Press the PMU reset switch for 1sec once, and once only. If the switch bounces it will be interpreted by the PMU as two presses, with an entirely wrong outcome. The PMU is extremely sensitive to stray charge, so make sure that the hand that presses the button is also in contact with the metalwork of the door.
Close the door, switch on the mains supply and start up the Mac from the touch-sensitive 'button' on the ADC display. Given nothing worse than the Mac's former confusion as the cause of its failure, you should be up and away. If not, failure of your PSU is a distinct possibility.

Computer idling sound | CHUD tools...

Hi there,
Since a few weeks (I guess since I installed OS X.4), I've noticed that my computer makes a subtle sound (kind of metallic) every single second. It's driving me crazy.
In the this page: http://docs.info.apple.com/article.html?artnum=86523 I discovered that my computer makes the the computer idling sound (the first one on the page).
I downloaded the CHUD tools, but I have no idea how they works... I don't understand anything! (Apparently, it will install a System Preference pane for the processor. With it, you can disable CPU nap, which lessens the noise for some.)
And turning the speakers up a bit won't help me because I work without music... I need quiet to concentrate.
Thanks!
Chris.

Krissserz --
There are various opinions on whether it will damage your machine over a period of time. It does indeed increase the temp' though (I have tested it on my 2.3 dual machine). My opinion is that you should monitor the G5 while using it with NAP off. In my case, it only varied by 10 degrees, which is not a lot.
Just do a search on the word "NAP" and you will see many emails on this subject. It was a hot (no pun intended) topic on this forum at one time.

CHUD tools failed to install (want to disable HT)

hey all.
I have a 13" macbook air (2011 late version) i love it but would like to turn off HT. i have Hyper-threading off on my gaming PC and i love how much less power it uses as well as less heat output.
well when i installed the CHUD tools it fails at the end. but im still able to install the processor system pref icon. when i open up the settings the settings are missing. like clock speeds are not being shown and if i chose to unchech hyper threading and or maybe a core the settings dont stick???
is this a known issue with macbook airs or OSX 10.7.2??
i really really would like to disable Hyper threading. please help me out. thanks

i have a late 2011 2.4ghz 15" mbp and am also interested inturning off HT. all the other forums i look at say There is a command you can use to turn of hyperthreading it is "sudo nvram smt=0" once you type it in it will ask you for your password. Try it and see if it changes anything becuase i have set the smt to 0 and nothing has changed for me but it may change something for you. what are you using to see how many active cores there are? istat menus?

Chud Tools 'Allow Nap' Problems

Hi all, before i go down the road of trying to get my powerbook looked at by an agent can anybody tell if they have had the same problems and managed to get them resolved via an apple specialist or will i just be fobbed off.
Here's the problem. I launch Pro Tools and the powerbook makes a real loud static fuzz sound. I untick the 'allow nap' feature in the processor pane of chud tools and the sound stops. Also when i'm using intense apps like FCP and Motion i get a grinding hamster wheel sound. Once again i untick 'allow nap' and the problem go's away. I think downloading a developer tool and messing with the processor isnt really much cop for a £1300 laptop. Can anybody shed any light and more importantly has anybody managed to resolve this problem.
Regards
Mike
PS: The sounds emit from around the top left of the powerbook and they are not coming out of the speakers.

As for the sound issues have a look as there is some idea about a fix comming in 10.4.5
http://www.appleinsider.com/article.php?id=1519
Likely you might have more luck with the UNIX forums under support/osx technology's /unix as maybe there might be inteligent life but not when I needed it.
PS: the NAP option is not permanetly disabled and if you managed to get it permanently disabled the you should be well on you way.
I just erased / reinstalled and avoided any unneaded files/programs and mine is running like a charm.
I even stress test it with UT2004 at max playable options for 5 hours spectating online and getting some good maps in the same time and it still runs like a charm.
There where just a few creaking movement noises as the part adjusted to the heat but it runs cool @ avg 60C.
Hope this helps.
Have you seacrhed for "disable nap" on google or macupdate.com etc. etc.
There might be a permanent fix there.

CHUD tools for current-gen 13" and Lion

Hello,
I have a current-gen 13" and I'm looking to disable hyperthreading and possibly one core and underclock using CHUD tools and hwprefs:
sudo hwprefs -v cpu_count=1
sudo hwprefs -v cpu_ht=0
When I tried installing the CHUD tools the installer went all the way through and then told me it failed, however hwprefs is available in Terminal. Running those commands shows me this:
* 2 processors available *
* processor hyperthreading enabled *
I'm glad it's smart and knows that stuff but that's not what I wanted. Does anyone have experience with this?

I just sucessfully installed the CHUD tools on 10.7.2, and am now using CPUPalette.app, located in /Library/Application Support/HWPrefs. What version of Lion did you try to install CHUD on?
Alternatively, you can go into the Preferences for Instruments.app, which is installed with Lion's XCode from the App Store, and turn off processor cores.

New chud tools 4.6.1 - confirmed working on MDD

Hello everyone,
I would like to take this time to say that I am happy to report the success of installation of chud 4.6.1 on my MDD 2003 dual 1.25 system. As you all know only 3.5.2 was the last known working chud tools. It appears that the new version also has nap mode built in. No further need to select it anymore. Below is a pic of the new layout:
How do I insert a picture from grab to the forums? I would like to show that 4.6.1 works?
Help.

Hi TTabby-
No worries....
Might want to have a look through This if you haven't already.
I do know that CHUD 4.5 Nap mode works automatically on my single processor machine.
Can't say about dual processor G4's.....
I will check further before I make any changes here, to my otherwise functioning-quite-well 3.5.2 Chud.
Good idea.
If it ain't broke, don't fix it!

CHUD tools universal ?

Does anyone know if the latest CHUD dev tools (4.3.2) are Universal binaries? I want to use some of the tools but I noticed there are pref panes in the tool set and I don't want them if they aren't Universal.
Anyone know?
Peter

Without stating the obvious, these are development tools for the processor, low level stuff so it is to be assumed you can't develop properly for a proc through emulation. Yes they are UniB.

Turning off one processor with CHUD tools

So I need to turn off one processor on my MBP running leopard 10.5.4 to solve a sound problem with Myst III Exile. When I switch to just one processor in the processor preference pane the computer slows down, which is normal, but what doesn't seem normal is that there are processing spikes that happen every 5 seconds or so. The computer seems to freeze during these spikes. I'm not running anything out of the ordinary. I have my linotype font explorer running, transmission torrent client running and thats it. Once I turn the second processor on again the computer functions normally with no spikes. Any help would be appreciated.

Thanks for stating the obvious, does anyone have any intelligent suggestions rather than casual observations?

Nap with chud in 10.5?

Will it be possible to activate nap with the so called chud tools in leopard using an mdd 867?
Message was edited by: Martin Heidingsfelder

I'm guessing here, but I think the problem with the cache showing as unavailable in CHUD 3.5.2 may be a reporting / display issue, rather than the caches really being turned off or disabled. I'm running Leopard on a PowerBook G4 1.5GHz and the CHUD Tools display the cache as off when the preferences panel is first clicked. But the machine still appears to be running at full speed.
Now, if I flick the CHUD option to 'on' (512KB L2 in my case) - no change. Flick it back to 'None' and things slow right down. Turn it back on, speed is restored, quit and reload system prefs, check the Hardware panel... and it's saying 'None' again.
It's definitely having problems, and I really hope someone can fix it properly, but I don't think there's a performance hit here.

AppleScriet CHUD Disable Nap G5 problem

I've been using an AppleScript I found a long time ago to automatically disable the nap function in the "Hardware" pref (installed with the CHUD tool v3.5.2) in the system preferences. Since I updated to Leopard it doesn't work and I get this error message:
ERROR: unable to initialize CHUD.framework - CHUD
function: utilGetOperatingSystemInfo()
status: chudBootstrapFailure[-11999] (src/chudUtil.c:432)
Here's the AppleScript:
"hwprefs cpu_nap=false"
According to what I've sussed out on the web, the last version on the CHUD Tools that had an allowance for the Hardware pref was 3.5.2. Anyone able to diagnosis this one? Is there a better place for me to post this question? Thanks in advance!

nothing?

Leopard and processor/NAP/CHUD settings/m-audio 410

I've got a G5 DP with the infamous white noise problem coming through my speakers that was only fixed after downloading the chud tools and disabling the NAP settings - does anyone know if I'll have the same issues if I install Leopard? Want to upgrade but don't want to waste my money if the noise comes back and I can't get it to work. Also, I'm using an m-audio firewire 410 that doesn't have drivers yet; has anyone used the Tiger drivers with success on Leopard? Hoping that Leopard will fix intermittent problems; system locking up, etc., that have plauged me for years...
Thanks!

This sounds perfect. I'm on a pretty chirpy G5! However, this going to sound really silly but where can I find the pref pane you mentioned. I've looked for the path you gave and I don't have a /developer directory. I've looked on my Leopard install disk and I can't see it there either. I then looked in the optional installs on the Leopard disk for something that might make sense...but sorry nothing looked right. I've also used spotlight to search for lots of things like 'developer' and 'Processor.prePane' but no luck.
Any help would be great - sorry to be such a noob!
Cheers,
James

Leopard + CHUD + G4 MDD and FW 800

Many know that CHUD 3.5.2 can be used to set NAP to cool down CPU, but only until 3.5.2, after that Apple took this feature off. There is another problem too, with Leopard this version of CHUD doesn't work.
So using Pacifist from http://www.charlessoft.com/ on CHUD 4.5.0 I found out that Hardware preference is included in CHUD 4.5.0, but not as a System preference anymore but as an application.
If you installed CHUD 4.5.0 you can find it at /Library/Application Support/HWPrefs it is called CPUPalette, just double click to run. There is no menu in this app, Apple took off all the good features. Click on the lower processor or on the minus sign to turn it off. Click on the window’s red bullet to close it. Just simple as that.
But I think most of us wont like it. I don’t.
Again using Pacifist I managed to find out that in CHUD 4.4.4 Apple included a System preference called Processor.prefPane and it has many good features. First of all, it works in Leopard, appears in menu bar, it is easy to turn on/off the processor, controls L2 and L3 cache, shows lots of information of your processors and also has the Processor Palette.
So, grab and install Pacifist, grab CHUD 4.4.4 from here ftp://ftp.apple.com/developer/ToolChest/…formancetools/ and mount it. Drag to Pacifist CHUD.pkg and you will see the contents of it, click on the arrow of System folder and Library folder. Now you see the PreferencePanes listed, give a single click on the PreferencePanes folder to select it and click Install in the Pacifist Window.
It will ask for your admin password and will install the Processor.prefPane.
I hope this can help many of you.

You don't necessarily need Pacifist. You can download *Chud tools 3.5.2* (the version known to work for MDDs!) here: ftp://ftp.apple.com/developer/ToolChest/Testing_-_Debugging/Performancetools/
You can download this applescript (which now works with Leopard) which will automatically turn on nap mode at startup.
Enable nap script (Leopard) here: http://www.macosxhints.com/article.php?story=20071101231643321
It's my understanding that a single cpu MDD default has nap mode enable already, so you don't need this if you only have one processor.
Also,see this: http://coolstuff.wordpress.com/2007/02/19/powermac-g4-mdd-cooling-and-noise-redu ction/ a great ongoing blog/discussion/comments of the MDDs noise and heat issues. Much information about fan replacement and Chud tools.

Tiger 10.4.4. Update WARNING! (CHUD)

For those who use CHUD tools to disable Nap mode (because of high pitch whine and other weird processor and firewire noises)
I recommend to uninstall older version of CHUD tools.
After I did software update my fans always started to get crazy 2-3 minutes after booting. No matter which app I started, even if any. The fans went so fast and loud I thought they are thinking that the 10.4.4. update turned them into some Rolls-Royce engines (used to "move" airplains) and they probably decided to fly my Mac away...
Then I realized I can not connect to the Internet, because my USB cdma modem "did not exist" even if I checked the connection and the power-on statement...
I uninstalled the CHUD tools and the problems were gone.
There is a new version of CHUD tools from 2006-10-01 available here: http://developer.apple.com/tools/download/
dualG5 2,5GHz 3,5GB RAM WDRaptor drives(no Raid) Mac OS X (10.4.4) Yamaha 01x, i88x, motu828, MidiExpressXT

to ifwuh:
this "chripping" noise is known mostly / and only probably when using firewire interfaces. Many G5 machines are affected-some people reported that changing PSU unit solved the problem....
After you install CHUD tools you have to reboot your Mac. Than will find new Processor pane under Preferences. Here you can untick (disable) Nap mode.
Good news is, that "the CHUD package installer no longer depends on the Xcode Developer Tools package being installed"
(taken from it's latest release notes)....
To everyone else: glad to see it helped
And tobytheuba: I haven't seen that movie, it seems that it is a horror movie right? No, I wasn't feeling SO bad because I knew that I am in OSX world, no Windows anymore, hence I hardly believed it must be solved immediatelly. And it was
