    You may be right, I don't know anymore.
    But say you bought a 09 Ford Mustang,... and word got out that line had problems. Problems that could cause even more major problems "down the road". You've read in the press of them, you can even see what they are talking about using your own new car. But Ford denies any problems, or worse, stays completely silent about them.
    So 2010 comes along, new 2010 Mustangs come out, and all of a sudden those problems don't exist in the new cars anymore. What would that say, and what would the reaction of 09 Mustang owners be?

    Well, wait to worry, I think. I'll give Apple the benefit of the doubt that they'll do the right thing. They don't want another G5 fiasco on their hands. If peoples very expensive new Macs keep shutting down like the gentleman's here did, just by playing a song in iTunes, they will be forced to address it and soon.

    Post back with how you make out, Pierre

    Read on AYM that people sending in laptops with the 8600M, even if for other problems, are getting those repaired while in for service. Lucky this isn't a fire or brake petal problem - or LCS which also are getting serviced.

    Okay, there is a beata flash 10.1 that offloads workload to GPU out today. And new ATI/Nvidia Windows drivers also are ready.

    OCZ lets loose the Colossus - OCZ's new 3.5" solid-state drive family
    Can you imagine 1TB SSD and it isn't even 2012? But you'll need deep pockets and a shot to calm your nerves if you even think of going for one!
  • Samsara Level 4 Level 4
    I read about the beta flash 10.1 just last night. That's good news. But it looks like a little squabbling will prevent Mac users from seeing the full benefit of it for awhile. If ever. When has Apple ever shared it's "secrets" with someone. Weird that these companies who rely on each other so much, seem not to like each other in real life.
    Still, it is good news. I asked Rob Art if he would look into both the iTunes heat issue and the flash issue, so that's good for him, he has one less thing on his plate. He said he would check both out though.

    It's hard for me to say, but even I can't think of a reason for getting the Colossus. Well, I guess I have so many drives already I don't need that kind of space and I'm sure for high end video companies they would be the cat's meow. It is a good sign for the SSD industry, they must really be here to stay. And as I noticed the other day, their prices don't seems to be dropping. The OCZ's seem to be even a little more expensive now.

    TOT, are you sure it was 2012 you made it to the other day?

    Oh, the feathers, they do fly. Adobe flash banned from iPhone; and the clashes of titans. Eventually, all these companies and vendors are just people, and I don't know why it breaks down. I left psych/sociology for math/science and engineering a long time ago.

    Microsoft is also planning on what Windows 8 will be, 128-bit being one possible feature. But also, What was learned between Vista and Windows 7
  • Samsara Level 4 Level 4
    Apple and Adobe,... I always thought they were bedmates...
    Maybe now that they have bigger beds, they've added lawyers between them to fill the void.

    Windows 8... I'm very glad our companies are looking for ways to improve our existing products down the line. But just how far down the line concerns me. Sort of a 285 thing. Which reminds me, I have to check out that link you gave. Don't know why I didn't.

    And by the way, I just got an email from an OCZ rep who says it's past time to install their latest firmware update. I'll give it a try today. A nice guy, I really like that company. I'll have to get a Colossus just to put on my mantle and admire it from afar...

    Ok, machine return from Apple.

    Temperature is normal... yes, is strange all that heat from iTunes or another audio program but the machine was tested working in heavy processing and didn't fail. The higher temperature was 176F.

    That's it... if the machine keeps working and don't shutdown, nothing wrong with that... Mac Pro generate lot's of heat when pushed hard... and, i have one old iMac that operates under 150F all the time and it's fine.


    p.s. - see other post's to mouse/4870 problem
  • Samsara Level 4 Level 4
    Heck, 65 Celsius? As I said when I play a song in iTunes, my temps are in the 80's. That's a problem.
  • abains Level 1 Level 1

    I think Apple has somehow clouded your view of this issue. You are right that 176F under heavy processing is fine, but listening to a song in iTunes is NOT heavy processing. These machines WILL fail prematurely due to the fact that even a light user who does no heavy processor intensive work will be cooking his CPU by just listening to media. Unacceptable and Apple needs to fix this ASAP...
  • The hatter Level 9 Level 9
    Nothing is being 'cooked' running 70*C.
    Pure bunk.

    Poorly designed code, yes, and that means Mac OS has to catch up to what Microsoft and Intel learned and now have in Windows.
  • Samsara Level 4 Level 4
    But 176F is 80C. And my temps go even higher than that, sometimes hitting the dreaded 90c mark. And all this on Nehalems, not another model is affected. Will Apple optimize iTunes code anytime soon for just their latest models? Because, frankly, I'm not comfortable with these temps.
    But like a few other things, I'm just going to let this go and see what happens. Just curious I haven't seen anything in the Mac press about it.
  • The hatter Level 9 Level 9
    I didn't mean to imply 85*C was okay, even if it is within what Intel's safe zone.

    Heck, I'd try to get it replaced, take it in at the least.

    I don't know when OS X will be rewritten, and that is what it is going to take.

    Use Windows 7 just to see what all that talk early about "thread locking" and stuff is about. (and I forget what thread I am in, but that was in another thread, wasn't it?)

    Optimizing code to optimize multi-core systems

    One process can either run wild and block everyone else, or one process can keep trying and trying and trying, and still result in 100% on one core.

    Open an app; one a window; do anything; and while you are, on my systems I see a quick immediate spike in temps, something that is amazing. I doubt iTunes for Windows is all that much better coded, so I'll guess that the Windows Dispatch Manager is, and why it runs cooler and so much better.
  • abains Level 1 Level 1
    Heat is the primary cause of component failure. Having a processor running at 60-70C unnecessarily is likely to cause premature failure of something. Having said that, the definition of premature must be taken loosely. If a component fails in 6 years, then maybe it would have lasted 8 if this issue was resolved. My worry is that these systems start running into issues just outside 3 years when peoples warranties expire. Apple is notorious for system failures just outside of warranty due to design flaws. Just look at the G5 Power Macs and the 1st Gen Intel iMacs. I wish Apple would just fix this...
  • The hatter Level 9 Level 9
    Your 60-70C though is not even what Intel would call "hot" for Xeon Nehalem processor.

    And I know a lot of Core i7 that of course water cool, push them to 4.0-4.2GHz and run within the thermal envelope.

    Intel warrants Xeon for running 24/7 at more than your 60-70*C. And it is Intel that designed the processor and cooling.

    Apple is still replacing and repairing G5's with LCS failures.

    With hard drives, it is the changing of temp from cold to hot and back over and over that is the most severe.
  • Samsara Level 4 Level 4
    Oh, I agree, it is definitely getting hard to keep track of the threads. Especially for ones like this, where it relentlessly keeps starting over. The first way back, was Loa, remember? And I believe we are no closer to an answer.

    I could never take this thing in anymore, so they'd have to come to me. And just like Pierre, although his temps are far from the danger zone, they'd say what other Apple techs have said repeatedly, "Hmm, that is odd, I guess it's ok though". One guy was told, 'Wow, that's bizarre. I'll give Apple a call about that and see what they say". Never heard the result of that one.
    And probably in my case too, they would see the one cut sata cable in the optical bay and say, Oops, that the problem right there. Then my option would be to spend maybe a few grand, bring the MP home, and find it still does the same thing. Because all the Nehalems do to some degree. Most people temps rise 20 degrees more when they play a song in iTunes. Pierre's case sounds like that.
    With my MP it may be a little like the G5 Dual 2.7s. The just pushed that machine a little beyond it's sustained capability, like from 2.5 to 2.7. Maybe that's the case with mine, going from the 2.66 to the 2.93 and that's why my Mac runs hotter than most. Even my base temperatures run higher than most.
  • abains Level 1 Level 1
    It may not be out of processor limits but it is still totally unnecessary. 30C is better than 70C no matter which way you slice it. There is clearly something malfunctioning to cause this behaviour, and I want it fixed.
