    Nice. Settings aren't identical to what i've been using. I updated my previous post. Image settings should be set to 1024*768. 8cores+GPU. If it behaves nicely on that, then certainly not an overheating issue (that is....with regard to your machine, mine almost certainly is).

    Adrian, bump it up to 1024x768, CPU*X+GPU
  • rockngroll Level 1 Level 1 (0 points)
    Very sad - Same problem here. Hard Freeze while every CPU-intensive Operation. iMovie rendering ends after seconds in a freeze. What do you think - wait for an update or back to apple? And it seems, that every macbook pro 2011 has this problem?

    Another user, similar issues. MBP 15 e2011, out of the box OS, 64-bit kernel, CTO with 8GB RAM, high density glossy screen. Have it connected to a 750GB lacie external FW drive, ethernet and 30 inch cinema display. Originally was seeing random freezes when either rendering a lot of RAW files in lightroom or rendering large panoramas (APG, using all 8 cores.) However, have used info in this thread to isolate it to a very simple set of steps:

    Steps to reproduce: (1) Reboot, let machine cool down (2) run photobooth (3) run 6-7 "yes > /dev/null &". Crash occurs within a few minutes. No other steps needed.

    Am running with the "automatically switch" option selected.

    On the phone with Apple tech support now. They think the machine is dead on arrival and want to replace it.
  • Chullo Level 1 Level 1 (0 points)
    To be determined. I'm hoping my replacement is from a different batch in which apple wised up and used less thermal paste on the machines. If not then I'll probably have to get a refund and wait 'till the issue is resolved (have 2 wks since time of receipt for full refund).
  • costa.bas Level 1 Level 1 (10 points)
    I started photobooth and I started about 10 of "yes > /dev/null &" and I let them run for ~10min. I could hear the fans going crazy but it didn't crash.
  • Chullo Level 1 Level 1 (0 points)
    Yea, that's a variable solution suggested by Jeremy. Check my earlier post near the bottom of the previous page to reproduce the issue.
  • Adrian J. Level 1 Level 1 (10 points)
    Further confirmation - pay special attention to the (CPU temperatures)

    after 807 seconds of testing (still running, see the green text "Rendering Time" for confirmation):

    ~5 seconds after test ends:

    ~20 seconds after test ends:

    Rapid temperature drop after the test, and no lock-ups of any kind during or after the test. Just laggy response during the test, as expected. 91C was my CPU's max temp, and those 8 blue squares at the top show everything was "maxed". Though I've seen the CPU hit 99C under Windows (but never higher). FWIW, I saw my 2010 hit 105C in Windows at some point last year.

    For me, the problem isn't overheating related. YMMV, of course. But for some of us, we get lockups that are unrelated to any sort of thermal event.

    hope some of this helps further direct the conversation.

    Very nice Adrian, thanks for giving us hope lol. Your freezing seems to be more of firmware/software conflict etc. My suggestion is to install OS X on another partition; On the same drive would b ok (so as to avoid having to waste time reinstalling your current partition and have the same problem persist). Boot from that virgin partition and try it out for a day or so with very few third party drivers installed. As for the rest of us.....we need a machine like yours! Btw, when did you get it?

    Will do.

    I ordered mine as a CTO on March 1. Got it on the 7th.

    Hopefully it is indeed some sort of software/driver conflict. Considering how few apps I ever really run, it should be easy to pinpoint if the issue is in one of my pieces of software or in one of Apple's apps.

    I'll be sure to keep the thread abreast. Best of luck to all.

    Out of curiosity, what temperatures are you guys' systems idling at? Mine right now is at 53C with Chrome open to ~30 tabs, Mail open and Audirvana playing music. I'd say it's usually sitting in the 50C-70C range. Those that are experiencing a thermal issue may have generally higher temps, no?

    Did that already .. problem persists. Still wondering if anyone knows of a MBP owner that does not have these problems? The problem that concerns me the most is during / after full screen gaming. I've had this with Dragon Age. I've checked the Dragon Age Mac forums and other users with new MBP are complaining there as well. I've see no response by anyone that indicates they are not having this problem.

    If a firmware fix is being worked, is it to work around a hardware flaw, or to deal with a real bug in the firmware....
  • Chullo Level 1 Level 1 (0 points)
    Mine idles pretty cool, if I max out smc fan control it idles in the 40s. Under apple defaults, it's usually in the high 40s to mid 50s. I ordered mine CTO on the 2nd and got it on the 9th, so we have similar times on that. I just ran another test doing all I could to try to cool it down (placing the vents toward a high speed fan while suspending in the air) and sure enough....crashed again in about 20s.

    Chullo-
    I ran smalluxGPU using the settings you suggested and didn't get any lock-ups (I quit the run after ~1000 seconds). It seems to me like there are possibly two things going on here -- one's an overheating problem and one's a driver/firmware issue. Hopefully Apple won't decide to cure the overheating issue by underclocking the GPU or throttling the CPU's turbo features.

    FWIW that was a very good stress test -- my CPU topped out at around 90C and my fans spun up to 6200rpm -- no other stress tests I've tried thus far have been able to generate as much heat. I suspect that was because it stresses both the CPU and GPU heavily.

    I know "it didn't happen without pics" so [here's a screenshot|http://home.earthlink.net/~kfscoll/images/MBP_smalluxGPU.JPG].
  • Chullo Level 1 Level 1 (0 points)
    Hey Michael, Adrian happens to be in a unique situation in this forum with his issue not being heat related. Most of our systems will crash when running the smallluxgpu test @ 1024x768on 8 cores + GPU.
  • Chullo Level 1 Level 1 (0 points)
    Schwa72-- I agree. And I hope they don't solve it like that either...my geekbench score is 10013 now, so I'll know if they took the easy road.

    Just did another one....10215.
