Clockworx: Which model celeron is it supposed to be? I've NEVER heard of a celeron of any kind have any sort of throttling. I don't trust Vista either. I didn't notice any difference between 4.8 and 4.9 regarding sleep, but I can't speak for everyone.

 

Here's the official spec sheet from intel for the specific one I have.

 

http://processorfinder.intel.com/details.aspx?sspec=sl9wn

 

Honestly, I'm kind of scratching my head as well. Notebook Hardware Control (my previous favorite for throttling on my old Pentium M laptop) doesn't seem to be able to make it work, but I checked the processor speed using CPU-Z. Vista wasn't telling me what the clock speed what, I just used Vista to set the "power saver" mode and noted the clock speed drop in CPU-Z. It seemed to work by throttling down the bus speed (originally at 133), with the multiplier staying locked 12x. So original speed is 133 * 12 = 1.60 Ghz, but then it drops as the bus speed throttles down. I've seen the core clock speed drop to around 400 Mhz if I'm not taxing the CPU at all. I fired up SETI@home to tax the processor, then paused, restarted, repeat......watching the processor clock speed rise and fall on demand.

 

I downloaded the RMClock utility and that seemed to do a very good job of throttling on demand. Vist seemed to either throttle at 800Mhz or 1.6 Ghz, whereas RMClock hit lots of levels in between and went down to 400Mhz when idle.

 

I'm actually more interested in getting sleep working than SpeedStep, I just found the experiments w/ CPU throttling on another platform to be interesting and might be an option for celeron users on Mac.

Not knowing how my CPU was throttling when I didn't have speedstep was irritating me, so I found my own answer. The celerons perform something called ODCM - On-Demand Clock Modulation. It appears to be a pretty crappy feature, and does little to truly increase battery life (except by limiting performance intentionally). Here's a bit more about it:

So it looks like I won't get any speedstep til I buy a new processor. Any hints on getting it to sleep?

Hey guys,

 

Guess what. Mr Paulicat has done it again. This time he has fixed Semthex's kernel to support Sleep - aka S3 Sleep. Usually , you could sleep the hack , but then if you try to wake it up..It does not. So , Mr Paulicat has found a way to fix it , its simply by creating a patched Kernel to support SpeedStep Extensions and S3 Sleep. So if you're on a laptop , you'll know that you need it soo much

 

Please bear in mind , this whole thing is 'Beta'. Meaning that , it might or might not work for you.

 

 

Please backup your kernel and your Library/StartupItems folder.

 

Oh one more thing , if you plan to use your Old Kernel back , make sure you delete the ACPI Folder from the StartupItems. Otherwise you'll get a Kernel Panic

 

Oh yeah , it does not work on AMDs !

 

Okay , enough of the blah blah blahing . Now lets get back to our topic

 

Firstly , please make sure you're using OSX 10.4.8 with 8.8.1 Kernel [and please make sure your Processor supports SSE3 Extensions and Intel ® SpeedStep ™ Technology [ this includes the enhanced version found on Core 2 Duo , Core Duo , Core Solo processors]

 

 

Link down

 

3. Install it and reboot . If everything goes okay , you should have OSX Kickin' In. You may want to test Sleep [if it wakes up - kudos] , if it does not [Then I am sorry]. Thirdly , you might also notice that this 'patch' increases your battery life. Whenever you unplug , the processor automatically goes to power-saving mode a.k.a the 'slowest' speed to 'extend your battery life'

 

where is the link

CPU Temp. Sleep doesn't work in 10.4.9 Upchuck 1.4 on Toshiba A200-TR6 core 2 duo 1.73 Mhz. The speed step display shows the current speed. My concern is battery and temp though. Not sure how accurate the temp display is. Cinebench 9.5 increases the rendering 2 cpu test to 69c ouch. 48 to 52c on idle. Battery seems to fast drain after 45 min the render test wouldn't run, or cycle higher than 800MHz probably from heat. It was Bloody Hot. S Off Topic I know . Got a ACPI error installing Jas 10.4.8 so took the easy route and used the above install.

Here is creen shot of my hackintosh It is plain old
uphuck
v1.4i r3
10.4.9
paulcats sse3 /speedstep patch

I have tried and tried to get the wake to happen goes to sleep fine but on wake there is HD activity but the screen still stays black.I love my hackintosh it is much faster then my xp or vista was I have nothing but osx on this laptop , by the way a

Dell 6400/1505
coreduo 1.85 gb (t2600)
1gb of 533 ram
40 gb hitatichi hd (Os X native)
intel 950 graphics 1390 truemobil
broadcom 10/100 ethernet
DVD rw /cdrw combo drive
anyway i give up I have tried this for a week.

Thanks all Bunkerboy

i have an intel core 2 duo 6320 processor. I nedd to install this kext or not install this kext?

 

Mac OS original give support for speedstep?

 

i'm using uphuck 1.4.9 v4ir3 and I install speedstep package of this CD (uphuck 1.4.9 v4ir3

 

sorry for my english

I'm having a bit of a problem...

 

I installed something called speedstep.pkg on my T7200 core 2 duo machine. The computer froze up right when I clicked on restart, and now the computer won't boot past the gray apple screen. I'm running JAS 10.4.8 with the 10.4.9 update (used the tutorial here, and everything was working fine until I installed that speedstep.pkg).

 

Anyways, can someone please tell me how I can remove the files/folders included in this package using single user mode? I would be forever thankful.

 

Your friend,

Well here's how I resolved the problem, thanks to Mr. Bluedragon1971:

 

At the Darwin bootloader, hit F8 to get the options prompt and enter -x to start up in safe mode (skips loading startup items). Go to /Library/StartupItems/ and delete the ACPICPUThrottler folder. Then you can delete the SpeedStep.app from your Applications folder. That should get rid of it. You can then reboot and should be working fine.

<br /><br /><br />MAC system quote" the item mach_kernel cannot be replaced because it is invisible", and how can i do ?

can i have the link to the file that fixes the sleep problem?

 

 

Hi.

May I ask where can I download it?

Thanks!

 

I'm going to third that inquiry. Could someone post a link? Is this thread dead?

Disable Safe Sleep (pseudo hiberbate), especially useful if ram is misreported - sleepimage is created the same size as reported ram.

 

To check how much space you are losing, open terminal and:

ls -l /var/vm/sleepimage

To disable:

sudo pmset -a hibernatemode 0
sudo rm /var/vm/sleepimage

reboot

 

to enable again:

sudo pmset -a hibernatemode 1

reboot

How can i get speedstep running on my 10.5.1 vanilla kernel?

You can't, unless you have a real Mac.

Is there a 10.5.1 speedstep-kernel? Where do i get it?
Look here: http://forum.osx86scene.com/viewtopic.php?f=16&t=2727

or go to IRC, irc.osx86.hu #leopard channel

attempts: I tried the solution today, it didn't break my Kalyway install but my computer is still not waking up from sleep.

 

First time I tried to use sleep after I applied the patch, when it woke I got a black screen and no response from Keyboard and mouse, so I decided to go into my bios to activate "repost video on s3 resume" then I retried it. It was still not working, when it woke up, I had a black screen but now, there's a string of text on top left.
