Macbook CPU throttling under full load, average temperature.

I would like to know 2 things:
1)Why does my "2.0 Ghz" macbook refuse to go beyond 1.67Ghz under full load and 57C. It simply will not go above 1.67Ghz, ever.
and
2)Where do I complain, send in feedback.
While I'm aware of certain benefits to lowering CPUclock to save battery power and avoid hardware failure at extreme ambient temperatures, I dont belive this is the case at hand. I paid for a 2Ghz laptop, not 1.67. I want my 2Ghz when I need it; under full load.

I was able to solve my throttling issues by removing the AC power and the battery, and then holding down the power button for 10 seconds or so.
I had a discussion elsewhere on this throttling issue you can follow over here: http://episteme.arstechnica.com/eve/forums/a/tpc/f/8300945231/m/713004711831

Dyeing under full load

Hello all,
my mac pro is getting the black reset screen after being under full load for a few seconds.
for example i can rendering out some 3d graphics or exporting some video from QT and the machine dies.
When it tries to reboot the main hard drive sounds like it wont kick in and i dont even get the apple start up sound. I have to remove the HDD and plug it in to another machine with a usb adapter to get it to kick in again. i put it back in the pro and i'm back in business, but as soon as i get full load it goes again.
drive and permissions repair comes up clean,, as does the apple hardware test.
this is a major problem because this system is the office work horse and i need to be able to put high volume stuff through with out a second thought.
And suggestions?
Thanks
Mark

Is your profile current on this? I ask because I'd guess you have Radeon X1900 which needs to be cleaned out every few months and the fans need to be kicked up a bit, too. So first check for dust bunnies clogging the intake on the graphic card.
The 2nd thing I would do, not related, is boost the RAM to something more like 4 x 1GB or 4 x 2GB.
Disk drives: configured as a dedicated boot drive, OS and apps only; scratch or editing drive array; media drive(s) or array. And image your OS for safe keeping then just use whatever backup tools you have, maybe to run automatically as well as manual.
Don't rely on anything less than Disk Warrior. Permissions repair aren't the problem and what you need to do is insure the directory of all your drives, and your data, is intact. And Disk Utility won't do that.
SuperDuper or Carbon Copy Cloner would help insure you have backups and good data.

Please take a look at the >OC Database< AMD section. How many do you see that are much over 4GHz? Those guys were pretty serious about their OC in the list without trying to kill the MB or CPU. I don't know of any AMD CPU that will remain 24/7 stable at those speeds and none for sure at 4.2GHz+. That would have been like me trying to run my X2 4200+ Toledo at 3.2-3.3GHz when I had it. Sure it would go 3.1GHz 24/7 f@h 100% load but not beyond that. It didn't overheat either but it sure wouldn't run with any kind of a load on it at 3.2GHz

CPU only clocks up to 1.2GHz on full load

I use Boot Camp on my Late 2007 17" 2.4GHz Macbook Pro, with fresh installs of Snow Leopard and Windows 7. I've used Windows 7 to diagnose my problem. I'm using Core Temp to retrieve my CPU performance info and Prime95 to stress-test the hardware.
Definite Problem:
My CPU will not operate at any higher than 1.2GHz under full load. It idles at 800MHz at 42 degrees Celsius, and warms up to 62 degrees Celsius under full load. I expect it to operate at 2.4GHz like it once did.
Best-Guess Diagnosis:
My computer has no battery (it physically expanded beyond functional size), and I read somewhere that the computer is designed to throttle down when no battery is present in order to prevent the computer from drawing more power than is available to it via the 85 watt charger.
Best-Guess Solutions:
1) If my diagnosis is correct, replacing the battery should undo the throttling cap. This is not ideal as it is not a long-term solution (batteries can continue to explode in the future).
2) I'd like to modify my computer's configuration to release the throttling cap/force full frequency. If possible, this would be the ideal long-term solution. This may not be possible if the charger is indeed bottlenecking my CPU's performance.
I'm looking for insight into my best-guess solutions or new solutions. Thanks for taking time to check out my inquiry.

Please carefully read and do both iMac SMC and PRAM reset s, if you need to do each 2X. It also may help to restart in Safe Mode to clear some caches.

MacBook is throttling CPU

Hi there,
i've got a MacBook Late07 and i discovered that if it runs under full load (encoding, etc.) the CPU becomes very hot. It goes up to 100°C very fast, then it lowers the CPU-frequency and voltage, to protect from overheating (Fan is blowing an maximum speed (6200rpm). Is this normal behaviour?
I can't believe that, because it means, that i can't reallly use my 2,2 GHz CPU over a longer time (longer than than a few seconds).
Thx for your help.

Well, then, that seems to be your answer. The computer is functioning normally and the temperature rises dramatically when you stress the CPU and GPU to maximum loads.
I don't see anything in what you've described thus far that suggests any problem. So, all I can add is that if this is an unsatisfactory answer for you that you take the computer in for repair to determine if there is a hardware issue. You can also try running the hardware diagnostics to see if anything pops up:
How to run hardware diagnostics for an Intel Mac
Boot from your original OS X Installer Disc One that came with your computer. After the chime press and hold down the "D" key until the diagnostic screen appears. Run the extended tests for a minimum of two or three hours. If any error messages appear note them down as you will need to report them to the service tech when you take the computer in for repair.
Some "common" error indicators:
SNS - sensor error
MEM - memory error
HDD - hard disk drive error
MOT - fan error

Macbook CPU full load, 99 degrees celsius

On my late 2008 13" Macbook 2.4ghz when I run 2 instances of "yes > /dev/null" for 10 minutes to stress the CPU, the CPU temperature is at 99 degrees celsius even with the fans going at the maximum 6200 rpms and while using a cheap cooling pad. I took the computer to an Apple store "genius" and he thought this was normal. Is anyone else seeing temperatures like this using this stress test method? I looked at the website http://www.intelmactemp.com/ and highest full load temperature I see for this computer is 84 degrees celsius. I have noticed problems running intensive 3d games where the system slows down from high temperatures and more so under Windows XP.
This computer is 4 months out of warranty but until recently I never ran intensive programs and so never noticed the problem. What can I do about this, I feel Apple should be responsible for this.

Hi MindBrain,
Saw your post last night but didn't have immediate access to 13" MacBook (Aluminum). So I've got a 2.4GHz unit with 4GB of RAM and ran two instances of the same command in Terminal.
All information is reported via iStat Pro:
CPU Temp before test - 76 (fans at 1998 RPM)
CPU Temp @ 5 minutes into test - 96 (fans at 2001 RPM)
CPU Temp @ 10 minutes into test - 97 (fans at 3100 RPM)
CPU Temp @ 15 minutes into test - 103 (fans at 5800 RPM)
CPU Temp @ 20 minutes into test - 106 (fans at 6200 RPM)
CPU Temp @ 25 minutes into test - 108 (fans at 6200 RPM)
For thoroughness, I also opted to run the test on a brand new 13" MacBook Pro, a 2 year old white MacBook 2.2GHz and another MacBook Aluminum. It's convenience I have when surrounded by 5600+ Macs across campus. All of the other machines also reported similar numbers, breaking the 100 degree threshold between 12-13 minutes into the test.
While I do not wish to discredit that URL, in all honesty I've probably had three times the number of entries on that website (611 as of this post) come across my desk in the past year for various reasons. So I really can't see that as being a valid resource to support an argument.
Not to mention it was your decision to not purchase AppleCare on your computer within the one year window, it was also your decision to not properly ensure adequate function of your machine prior to conclusion of the one year limited warranty. There was no responsibility on behalf of Apple to obligate you to stress test the machine 4 months after the one year warranty expired.
Lastly, is the sluggishness only in Windows XP or is it occurring on the Mac side as well?

W520 corei7 2720QM - 1 core is throttled under load!

Hi all,
I've been using my w520 for almost 2 years. It ran really great until recenty (these 2 weeks), I noticed that the core 2 & 3 constantly ran 20 degreer higher than core 0 and 1 under stress (i.e. wPrime) - please see img1 below as the screen shot of CPUID that shows the temperature under load.
In HWiNFO64 (img2) also shows that the core 3 was THROTTLED under stress.
All cores look fine after wPrime finished (img3).
Here's the configuration: corei7 2720QM, 1000M, 8GB ram, 500HD.
I just updated the bios to ver 1.38 in December, I'm not sure whether this is the cause of the 1 core throttle or not.
Has anyone experienced the same thing? Or does it sound like a CPU failure to you?
Thanks!!

Ok, I've reverted the BIOS back to ver 1.36 and then 1.32, the same throttling is still happening when running wPrime. Core 2 and 3 are consistently 20c higher than others when under load ...
I recall that the temperature on all the cores under load was like 85c max before ... and the machine was able to complete wPrime 32M under 10s, now it takes >11s everytime due to the throttling.
I've called Lenovo support 2 days ago, they said their safety team will contact me as it sounds like an overheating issue. However, i still haven't recevied any call from them ...
Can any tech. support from Lenovo help on this issue please?
Thanks!!

Retina Imac`s M295x GPU Temperature is 105°C @ Full Load?

Whats about the temperature of the M295X ? At full load it reaches 105°C within a few minutes and then it seems to be throttled.. I use my mac as a work horse 6 hours a day, so i am concerned about its longevity. Will it survive that high temps for many months or even years?
I have apple care but i dont want to have a big paperweight at the end...

I have just played Watch Dogs, Ultra Details, in Windows 8.1 (All Patched up, and the latest Drivers).
I have an M295X. Core i5 4690 CPU. And yeah it hit 105 degrees for GPU and 72 degrees for CPU... the fan I guess was at around 2000 RPM...
After that horror show, I downloaded Macs Fan Control, and set it to 2300 RPM, CPU temp at least got down to 65 degrees
Ambient Room Temp is around 20 degrees and not too humid, my room window is open there is some cool air blowing so pretty good.
I guess I'll wait for Winter to game haha. Or I could just game on my old WinPC
Seems like there is only 1 Fan thou.

High cpu load average

Hi Experts,
I have a SOA deployed on AS 10.1.3.2 which is integerated with BI EE 10.1.3.2 on OHEL 4.
With this setup, I have seeing very high load average on cpu side. When I stop the soa oc4j the load average comes to normal level of under 1. While with soa process started it goes as high as 15 which is pretty abnormal.
Any pointers to debug what could be the issue will be helpfu.
Thanks,
Rishi

Why is my load average always above 1 regardless of cpu usage?

My load average is often ridiculous. For example, when I wake from sleep it's usually 45 or so. Even when I'm doing nothing with the machine (CPU is about 10% in each core) I still see load averages of 1.2 to 1.6 or so. Why would this happen?
Is there a way to figure out what is causing the load?

Activity Monitor could see what happens on your MacBook.
Resetting SMC could solve the problem.

MacBook Pro Retina 2013 load average constantly above 1

I have a recently purchased (3 month old) MacBook Pro Retina - Late 2013.
I've noticed that the load averages appear to be rather consistently high.
So after a fresh reboot, with nothing other than background applications and the dashboard running, I've noticed that the CPU load stays above 1.0
The CPU itself is idle, at 100% nearly all of the time, it certainly doesn't correspond to '1' unit of load on this system.
I suspect something is amiss but have been unable to figure anything out.
I have tried the instrutions for clearing the SMC and this does not appear to have sorted anything.
The in-built diagnostics suggest nothing is wrong.
Any thoughts?

Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.

High load averages, low CPU usage

HI,
I recently upgraded to Lion and I am noticing high load averages ~0.7 for my system. The CPU is, however ~95% idle. I am not running any intensive apps. I first thought it is an I/O issue, but I have almost 500 MB free memory, and there is no disk activity. The system is perfectly fine, with all the eye candy/animations running smoothly. Is this a bug?
Thanks for any help.

Same problem here
Did a clean install of Lion, moved everything manually. System was clean and running fast. Then, for some reason started to slow down after a few months. My last system (macbook snow leopard) was running fine for 3 years.
I noticed HIGH load averages (over 2.5!) while CPU is ideling (only 'round 30% for user and system). System is slow and CPU gets hot, resulting in loud fan noise.
Googled a lot, did standard maintenance tasks, tried to pinpoint cause - nothing so far. Will update when I find out more. Maybe someone else has a clue or Apple releases a fix. Fingers crossed.

System load average over 1.5 while cpu idle

Running 10.9.4. My load averages are continuously around 1.5 or higher while my cpu is around 95% idle, no apps running, I've just rebooted and logged in. This is very common now for my machine. Any suggestions? Thanks

On Unix systems that are idle I generally see near-zero load averages. I would expect OS X to be in that general vicinity and seem to recall seeing near-zero numbers in the past when the system is idle.

Persistent Active Requests causing high CPU usage and load average

Hi, we've deployed a JSP application on standalone OC4J talking to Oracle DB. The whole thing runs on Sun Solaris. On some occasions (still investigating what causes this), the number of active requests rises (as seen from EM console) and never drops down. The weird thing is, the load average numbers are proportional to the number of persistent active request. If there are 3 active requests, load avg will be [3.x 3.x 3.x], and whenever persistent active request exist, CPU usage will shoot up to over 90% (usually between 95% - 100%). When the system is running normally, CPU usage is usually less than 20%. Is it possible to track down this problem and how? Many thanks.

Welcome to Apple Discussions!!
The icons on the right of the menu bar … show a beachball when I put the cursor over themWell, if this was your only problem I would put it down to a corrupt preference or cache file. Nevertheless, it is worth seeing how much this helps.
The file you need to trash is 'systemuiserver.plist'. But there are potentially two of them, plus it is best to delete your caches as well, so ...
In "/Users/<yourname>/Library/Caches", delete everything
In "/Users/<yourname>/Library/Preferences", delete com.apple.systemuiserver.plist
In "/Users/<yourname>/Library/Preferences/ByHost", delete com.apple.systemuiserver.xxx.plist where 'xxx' is a 12 digit (hexadecimal) numeric string.
See if this improves the situation, and post back with any remaining oddities.

Hi, I'm going to buy the new MacBook AIR full loaded but I have been reading all the discussions here and look like it has so many problems. My other option is the MacBook Retina.

I am worry about these amount of problem that I just read about MBair. I want to change to apple because most of my genetic software runs very good in these computer. As I said MBP retina is my other option. I am thinking to buy a full loaded MBair. I will appreciate your comments or/and recomendations. Thanks

Keep in mind what you are reading here is a biased sample, by definition. People mainly come here because they have a problem. A user who is not experiencing any problems is very likely to have never eveh heard of these forums.
Keep in mind that Apple sells millions of laptops every year, and you have no idea how many of them do NOT have the problems you see being discussed here. And if there were truly huge numbers of dissatisfied customers, how has Apple continued to sell so many computers consistantly for so many years?
