Okay this was the first time running Cinebench so I hope I did this correctly; I just ran all tests.

Specs are: 2009 Mac Pro 8x2.66GHz, 12GB RAM, 2x1 TB HD, ATi Radeon 4870

1. No Audio/HDs
OpenGL: 5271
Single CPU Render: 2832
Multiple CPU Render Test: 21910

2. Audio(iTunes playing an .mp3 loop)
Open GL: 5271
Single CPU Render: 2819
Multiple CPU Render Test: 21060

3. FW800 Transfer(WD Studio Edition)/No Audio
OpenGL: 5087
Single CPU Render: 2817
Multiple CPU Render Test: 21913

4. No Audio/HDs
OpenGL: 5370
Single CPU Render: 2821
Multiple CPU Render: 22380

I forgot to log the starting temp, but it generally is around the low 30 C without audio but the machine averaged 61 C, with a high of 63 C when the music and hard drive portions of the test were conducted.

Your scores don't really move at all. Mind doing the tests again restarting the app everytime?

Cheers!
 
i think this is pretty much the finished product, i think dragonforce should send this off now.

>Summary (Title):
25% Performance Degradation Due to Excessive Power Consumption in 2009s Mac Pro

>Description of the Problem:
2009 Mac Pro family computers suffer performance degradation up to 25%, consume excessive power and thus generate excessive heat during any simple audio playback and/or some firewire traffic, although being at low CPU load.


>Software Version of OSX?:
10.6.2

>Does it happen on a previous OSX?:
Yes, from at least 10.5.8

>Is it seen on any other OS (Windows/Linux)?
Not seen on Windows, not tested Linux.

>Which Mac computer is produced on?:
This has only been seen on 2009 Mac Pro

>Which Year model of Mac is it produced on?
2009 Mac Pro

process of reproducing the performance Loss of up-to 25%
1. play a audio file through this process
2. Using 1525 1080p JPEGs, time to encode from hitting "Save" from the export menu into a 1080p, 10Mbit H264 mov file. Timing stops when it finishes.
3. note time taken for the whole processing
4. repeat this with no Audio file playing
5. Notice a big difference in time we noticed the following:
7 Minutes 24 Seconds (no Audio)
8 Minutes 33 Seconds (+11.9%) (with Audio)decrease in performance when playing audio. (see benchmark section for more details.)

>2nd way Process of Reproducing high load & heat issues:

1. Copy large files over Firewire
2. Observer large temperature increase (without CPU load), also power drain
3.

>3rd way Process of Reproducing high load & heat issues:

1. plug in any external audio card such as a firewire audio interface.
2. Observer large temperature increase (without CPU load), also power drain
3.

>4th Process of Reproducing the Temperature issues

1. Install/run Temperature Monitor or iStat Menus
2. Play any audio (eg. an iTunes track)
3. Observer large temperature increase (without CPU load), also power drain.


>How long after a reboot does it take to reproduce the problem using the processes above?
Immediately after following the processes above.

>Actual Behavior of the computer?:
1 Heat generation.
2 No fan speed increase
3 No CPU load indicated in Activity Monitor
4 Performance loss

>Expected Behavior of the Computer?:
To play a tune in iTunes (or any audio app), negligible power drain, no discernible temperature rise.

So as we can see, major, major issues...

>How often is the problem seen (out of 10 attempts of trying)?:
Every time, perfectly repeatable symptoms.

>how long after a reboot does it take to reproduce the problem using the processes above?
the problem should be visible instantly after running through one of the above processes.

happens in any/every circumstance (all times of day/year).

>Are there any Applications running whilst the issue is produced?:
Symptoms occur in virgin new install and heavily loaded system, with minimal systems processes in idle or when running any other applications.

>What are the symptoms of the problem?
CPU temperature rise (under load into the 80C range or higher),
no fan speed increase,
power drain,
performance loss.

>Does a reboot of the Mac fix the problem?:
No. Nothing remedies or avoids the problem.

>Does Repair permissions fix the issue?
No.

>Does Resetting SMC Controller fix the issue?
No.

>Does a PRAM fix the issue?
No.

>Does a Clean install fix the problem?:
No.

>Are there any ways of temporary fixing the issue (deleting files,not running certain apps etc)?

found by csmallman
by remove AppleIntelCPUPowerManagement.kext in /System/Library/Extensions/ and rebooting.
I finally found some time to do this, and conduct some testing. I am happy to report MAJOR PROGRESS.

Good News
Temperature no longer increases when audio is played
CPU appears to run ultra cool compared to before with max core temperatures under a stress test hovering around 80C
System seems stable

Bad News
There seems to be a performance loss of approximately 10% across all tests (Geekbench, Cinebench, Xbench) when compared to tests conducted with no audio playing prior to removal of the kext
Performance seem to be comparable to an unmodified Mac Pro playing audio. Multi-threaded benchmarks (ie. cinebench multiple cpu render test) are the exception and score slightly lower even than an unmodified system playing audio
I don't know what other features of the processor are not working with this kext removed
CPU consumes 21.5 watts at idle now as opposed to 3 watts before (I suspect Apple screwed up with this kext which should be switching in and out of CPU power saving state
Mac Pro doesn't awake from sleep correctly.
 
Hello, brave also-Apple-customers, please excuse if my English isn't 100% polished since it's late in the day and I'm not a native speaker.

At first, big compliment for your great work so far. Work that had been Apple's job! But they also seem to have to save money in those days so let us do the beta-testing. A strategy which was traditionally attributed to Microsoft and one of the great arguments that Apple “thinks different” (I hoped so).

I've read this whole thread (which took some days ;) ) since I also have temperature issues on my MacBook (fresh end 2009, 2.26 GHz C2D, polycarbonate unibody, OS X SL, my first Mac!), however not with respect to audio. So my issue only seems to be the awkward fan management in OS X SL (one of your 4-5 points, see below).
the problem is not related to Macbook or Macbook Pro: it's a MP-only issue.
So if your Macbook has a similar problem it should be defective.
 
A few thoughts here...

With all the high-power users on this forum, there isn't anyone who has any connection with Apple corporate that can help out? Have we exhausted all the options of trying to contact such a person as an interface into people at Apple who could actually make a difference?

Perhaps it's the thread name that makes it less visible to others that could potentially help us? Maybe we should start a thread for "PR" purposes entitled "YOUR 2009 MAC PRO IS DEFECTIVE. TURN ON iTUNES TO SEE". The current "Audio Decoding... etc. green factor" doesn't have the same sense of urgency and seems to address the audiophile Mac user--not every 2009 Mac user, which it should. The way I see it, we need to network our way to the people who can solve the problem. Hoping Apple will notice us here is not the best approach in my view. For example, look at all the complaining that has gone on with regard to Apple's ridiculously poor miniDisplay port to dual link DVI adapter cable. The thing still doesn't work properly after having been on the market over a year. Apple continues to sell a defective product. Even Apple's website has hundreds of exasperated comments trashing the cable, and yet, Apple has done nothing. It pretends the problem doesn't exist.

By bypassing the standard call-screen "Applecare" first line responders and useless Apple geniuses and instead going straight to the engineers themselves is our best approach, in my view. How can we accomplish this?

Good thoughts, and I agree. I however am exhausted with this issue. I have been told 5 times that the issue is within limits. I have been told to purchase my music from the iTunes store to avoid issues. I have been told to avoid listening to audio if it causes a performance problem. I have had Apple Engineers tell me that this is all normal behavior and no fix is in the pipeline. I have been threatened by Apple Customer Service, and told that my Applecare agreement will be terminated with immediate effect if I share details of my case with the media. I have wasted countless hours emailing numerous editors at Apple publications, only to be ignored because they are afraid to publish anything negative about Apple.

I am honestly out of steam. This Mac Pro was a $5000 mistake that I will never make again.

I have been following this with you for some time - one last suggestion - why not try these folks: http://www.theregister.co.uk/ I try to read their column every day. This site doesn't seem to need to curry the favor of the manufacturers to maintain a living. With a tagline of "Biting the hand that feeds IT" it just might be worth one last try.

Good thoughts, and I agree. I however am exhausted with this issue.

Big empathy from here too. And you have put so much work into this smacman.

Reading around perceptions of the iPad a quote came up which rang a bell: "Apple is moving from technical culture to popular culture". Our issue is technical. In technical things Apple do whatever they unilaterally choose to do, only internally. With the unwashed masses like us, their interests are marketing and selling.

I wonder if the issue is not this MacOS bug, but our being stuck in the past. Apple IT has moved on and we didn't realise it. They are a gadget company now (and very good at it), we are dumb consumers of gadgets (OK a $5,000 ones, but support is the same if it were a $59 one).

There are other worlds that probably suit us better, Open Source, Linux, even Windows. Anyone reading this cannot really be prime Apple customers. It is a matter of consumers versus thinkers. Apple Think Different has become Don't Think, consume and conform.

Back to smacman's bereavement analogy. Exactly. But it is not loss of faith in Apple, or frustration with the roasting bug, it is being faced with the loss of our model of how things work. No longer being able to assume that there is any sort of fair play. Apple is a dictatorship, they are in the gadget market, and their fans love them for it.

Your democracy just went Stalinist, and you are appalled to realize that your investment in Apple (the mental one) just crashed. You are almost peeved that the bling and consumer success that Apple has wrenched from the world is making them a darling to the masses and investors.

So to your future. Walk out of the warmth into the cold unknown? You will not be in fashion, your company will be similar outcasts, freedom lovers. Or give up, be pragmatic, close that chapter of your life, move on, join the herd, be a consumer. Treat your gadgets like cabbages - if there's a worm in one, return it, bin it, or get something else. Just don't go on about it.

Will Apple go the way of IBM, then Microsoft, the Roman Empire, ... hang itself through its own arrogance, unilateralism, through believing its own propaganda. Probably, but that will take time.

Apple is waging total war, commercial war, pursued without mercy. Every company does. You are cannon fodder.
And there you were hoping to be objective, neutral, relish technical excellence, extend your being through reliable and natural digital means.
But that's not what Apple allows, you have to live the way they determine. It can be hard to be indifferent/neutral, so often it is a matter of being with them or against them.

Apple owns the iPad CPU design & manufacture, the OS, software development tools, apps, stores, marketing, domain words, support, ... Even app developers are largely Cocoa copy/paste artists now. They want to own you too.

Your desktop box is legacy. The same old cheese grater box, Intel's latest inside but otherwise mediocre. The price you paid was a premium for a limited production run. Easy money for them, if you must stay in the past. It may look like a computer as you understood they were, but it is not the same. It is a gadget, just a big one.

The world has moved on.

Pity this machine roasts itself, if it's the last one, it could have had a very long life.

Your choice: Give in, join the herd, bling up, accept being a gadgeteer. Or move on, join Robin Hood and live in the woods.

PS. I think you hit the spot smacman when you were bitten for mentioning getting through to the media. The only reaction we have had to date. So the battle plan seems headed that way. Quality newspapers, tabloid headlines, blogs, TV, radio, … we need to work out an equivalent message to the recent one for Apple. A strap line that is inflammatory but honest and constructive.

Any copyrighters, journalists, or PR people care to volunteer suggestions of words that the media would like and also will kick Apple into constructive action?
 
It sounds to me like you have already recognized the jist of the issue. Apple has moved onto 'gadget' products and are neglecting the consumers who still purchase their work-station computers with the assumption that they are getting a reliable machine that is worth the premium.

It'll be hard getting the press interested in a story that revolves around Apple's smallest market having overheating issues that as of now hasn't caused mass failure in 09 Mac Pros.

I'm guessing more attention could be gained by spinning the story as Apple's neglect to a market that helped make them what they are today. How the pro user market has been left asking wheres the support? Wheres the company that once took pride in creating durable computers?

If I were a caual Mac fan who owned the latest iPod touch or whatever, I'd be much more interested in reading an article about the company whos priorities changed. A more broad overview that mentions the audio issue as a representative of the predicament that current life-long (and 09) Mac Pro users face.

An article about a heat issue when playing audio in 2009 Mac Pro is quite niche, it'll be hard getting attention from people other than Mac Pro users.
Write an article that entices any Apple consumer to read it by talking about how Apple's products have changed and that the consumers it targets have changed. Compare this current state to how different Apple was 10 years ago. Bring light to the audio issue as a negative of this change.

anyone here familiar with the Consumerist website (http://consumerist.com/)? They may have email addresses, phone numbers or contact information for us to launch an EECB (electronic email carpet bomb). This means we get to board members, directors, etc, let them know the short and repeatable version of the issue.

We also let them know some of the "rubbish" we've been told, such as not playing audio on our VERY expensive computers.

EECBs do get results in most cases, it raises visibility and companies do react, especially if we get the Consumerist to carry the story on their site.

Anyone?
 
I have been threatened by Apple Customer Service, and told that my Applecare agreement will be terminated with immediate effect if I share details of my case with the media..

:eek: WHAT?


If somebody from Apple would told me that, than that would be definitely the last time I ever bought an Apple product!
Neither the Pro, nor OS X is so good that I could excuse such an insolence!

I'm not paying thousands for a seriously flawed machine PLUS extended warranty that they cancel in case that I make THEIR faults public.

That insolence definitely needs to go public! Playing the nice guy to the media and being a first-class ******* to their customers. Nice play Apple!

Great idea. Smacman, you have done a great, great job so far. Gentlemen and ladies... it is time for the army of 2009 Mac Pro owners to start the drumbeat. We need to bring this problem to the fore. We need to mobilize. We can't just sit here with very, very expensive machines and all just take it from Apple. Especially where this fix appears within reach with some engineer's time on it.

It's time to start the fire under their proverbial behind...
 
Wow. Just when I finally make the case to my IT dept to let me switch over from a Dell 690 to one of these. Back to the drawing board.
 
i want to try something. someone interested in finding a fix, pm me with your AppleCPUpowermanagemtn kext.
 
guys im pretty sure I came up with a fix.

can a 10.6.2 09 mac user please PM me. pref if you're one of those who can test and measure cpu load and power usage, aka no nabs.
 
Xeocon, agreed.

A general story is how Apple staff threatened smacman when he mentioned speaking to the press.
 
I sent an email to a writer at the register that wrote the article on the problems with the imac 27". Just hoping for a reply now lol
 
Hey guys,

Just catching up on this issue. I'm getting ready to buy a Mac Pro whenever they release the new one. Since I'm an audio engineer and composer it is not good news that the machine struggles with audio. Does this happen to every 09 Mac Pro or just some? Does it happen to any other model of Apple computer (imac, mini, etc)? Has there been a determination if its a hardware or software issue? Does it happen with WAVs, AIFFS, etc., or just MP3s and AACs?

Thanks!

Mike

Not to be a douche, but reading through the thread will answer this. I spent a good hour (I'm buying an 09 mac pro today) reading through.

To answer, yes it seems to affect most machines. With most types of audio/audio program. Not in windows. Not happening in other models. Seems to be a software issue.
