My 17" with 8gb freezes more often than my POS PC with a dual core and 3gb of ram.
I'm pretty disappointed

2011 MacBook Pro Freezing under load

Did the tests...nothing.
So I got my 2011 2.2 15" HR-AG 500GB 7200 launch week. and I tried to tax the **** out of the processor via various apps like handbraking to mp4@720 from a dvd which ran for about 40 mins at an average of 96% cpu usage(super hot), also did a 10 min HD video export with motion graphics from final cut pro, also ran games like starcraft 2, left 4 dead2, and civ5 all at max res and max settings for an hour each. I really tried to break this thing. It definitely ran faster and cooler than my old 2.8 and proved to me this computer is awesome. BUT still nothing froze and everything went smooth. So I'm wondering if this could be a certain batch of computers or something of that sort.
I feel bad for everyone with the problem I know it would drive me crazy.

i tried the terminal method from that apple forums thread on my 15" 2.2ghz mbp and had it running for about 5-7mins and i checked temps and fans and only touched 90 degrees maybe once or twice and fans were at around 6200 and i turned ON the discreet gfx and was running two 1080p youtube vids at same time and a vimeo hd vid and had no freeze
i had no idea how to reverse terminal commands so i rebooted

Either Ctrl + C... or just close the Terminal window.
Tried the yes > /dev/null test with 16 instances and PhotoBooth running, and nothing to report. Currently downloading MacPorts to see if I can build boost with PhotoBooth for the other test...
Could you try booting in 32bit and see if the problem is fixed?
9to5Mac reports that the new MacBook Pros boot by default in 64bit which could cause several problem, especially with VM software

Mine has clearly frozen like this several times. The boost compile trick locks mine up too. Don't think I have SSH enabled, as I couldn't SSH into it from another PC.
It's done it twice while playing WoW, and interestingly enough, displays the same symptoms occasionally while shutting down Windows 7 in Bootcamp. Not sure if anyone has mentioned that in the Apple thread or not, but I've seen at least one other person post up that Windows 7 froze on the shutting down screen causing the fans to go to max and requiring holding the power button to shut down.
Interesting side note. When WoW locked up the computer, it was clear that the system wasn't completely frozen. I could still hear people talking, live, in the voice chat software. I just couldn't get any response from the keyboard or screen.

I can confirm that this is an issue (17" MBP, 2.3 Ghz). Just today, I deliberately taxed my machine: I played a 720p video in the background, opened 40 tabs, processed 10 RAWs in DxO, played Football Manager 2011, opened two Word documents and retouched a RAW in PS. Sure enough, after about five minutes everything froze
It also happened yesterday evening under much less load. The interesting thing about that first crash was that music kept playing in the background. This indicates that the problem is isolated to the display/GPU/GPU-switching; the other hardware continues to function.

I converted a batch of things off a DVD with Handbreak and it was maxed out the entire time. Temp was probably about 85C or so.
I've got iStat Menus and SMFancontrol and not once did it freeze up and I've done quite a few conversions already.
Haven't had any issues with Parallels either.
Maybe for once I got lucky. So I wonder what's going on.
- 6 Instances of yes > /dev/null &
- Re-encoding a 720p version in Handbrake.
- Parallels running with Windows 7 inside with 4GB RAM installing SP1 at the moment.
- Temp is 86-88C on the ATI card, Integrated was also tested.
- Been running for over 30min.

I have a 2011 17" 2.2Ghz MPB
I just tried handbrake and watched a 1080p movie at the same time. It froze up 4 times in a row. First time I could use my mouse and the caps light on/off was functional. Sound was still playing but video was frozen.
I filmed the last lockup in HD. GPU diode 77C CPU maxed at 92C. The machine never crashes completely but the video freezes and holding the power button for 5+ seconds to reboot is the only way to reset the machine. No crash reports after reboot.
What do I do if replacement machines are all going to do the same thing?
I've had this laptop for 3 weeks. Bought in person at the Apple store.

I am right now running 6 instances of yes > /dev/null and using the ATI card and the cpu is 85c. Been runnng this test for about. 30 min and its soild as rock, no issues at all. The fans are spinning at 5300 rpm. No hangs what so ever. Been using the build in to under 30 hour stresstest and no issues...
This is a MBP 2011, 2ghz 8gb ram, no ssd. latest updates and so on...
maybe its a bad first batch? I got this computer on Friday.
I hope apple solve it.

Try converting a 1080p movie so your CPU is pegged. Then watch the same movie at the same time. This will crash it. Mine lasts 1-5 minutes. Use this software http://codykrieger.com/gfxCardStatus and switch back and forth from I to D. It only crashes in D. Check youtr CPU my diode was 77C when it crashed. It's only 68f degrees in my house. It's going to be even worse when the temps are up.
It's not the CPU crashing, it's the GPU causing problems so get the GPU hot by watching a 1080P movie while running handbrake.
I think this may effect the new 13in macbook pros as well. I was trying to convert a movie via handbrake yesterday along with emptying some trash the secure way and all of a sudden it frooze. Temperature was around 95 degrees while the converting was being done.
Why do some people think istat has something to do with it? So the consensus so far is that it might be fixed with a firmware update?
also, for whats its worth, i was the i7 model with an ssd and alot of ram installed.

I just updated some more info in my original post.
CPU is absolutely and utterly pegged, converting the HD video with parallels installing SP1, 6 instances of the crashed test.
Just can't get it to crash at all, and this thing is going FLAT OUT.
LoL, we got the same issue you and me. I cant get it to crash either even running handbrake to convert a 1080p to 1080p, view a 1080p, running 6 instances yes written to dev null...
Damn apple!

OK I've only learned about this problem an hour ago but I've found "several" ways to get it to crash.
It seems like it's a low voltage while hot issue.
Turn your monitor on full brightens before doing the tests.
Dev null, handbrake and run a 1080P movie. If that doesn't do it then switch between I and D a few times with this program. http://codykrieger.com/gfxCardStatus
I also found another way. Set Laptop on Bed. Reduce airflow a little. "Top and back airflow" a rag will do it and the same thing happens when the GPU temp climbs a few degrees. The trigger point is full load and just a little more heat. 74-77C on the GPU diode does it for me.
I'm not saying to trash your machine. Just reduce the airflow a tiny bit to get the CPU a little hotter. 2-3 degrees C. At full CPU load and full Brightness the Voltage to the hot GPU may be too low.
The fix will probably be a firmware that throttles back the Turboboost on the CPU's!!!
What sucks is that this problem is probably going to be a nightmare in the summer. I'm going to heat a small room to 95F degrees tomorrow and see how much "room" temperature plays into the picture. It's only 68 degrees right now.
Hmm. I think you're on to something with the brightness. I just tried the /dev/null thing with photobooth open and it didn't lock up. Cranked the brightness up and it locked up in a matter of seconds.
2011 15" 2.2. SSD 8GB
edit: running test again, same scenerio and it seems to be doing fine. Fans blowing at 6200rpm, temp at 88*C. Processor pegged out at 97.8% according to top and activity monitor.

ugh
All 5 of ours at the office do it ( 2.2 15" ) mine seemed fine but sure enough today it froze up. Mouse cursor moves and I can access files on the machine but the gui's dead. I left it and it actually finished encoding with handbrake in its zombie state. Needless to say we're not impressed over here.

Yea I "think" the power is sagging to the hot Discrete GPU. Hopefully they can bump up the GPU voltage .1-.2 volts instead of throttling down the CPU or Turbo boost. You can see the battery Charging is kicking off at high loads. Running this http://codykrieger.com/gfxCardStatus while in integrated only mode keeps it from crashing but the video is all choppy while the CPU is under load.
Yeah, I had the bootcamp shutdown issue once also, which I thought was unrelated until you mentioned it.
Run the Windows User Experience test thing in the VM and while its running hit the expose/dashboard keys as fast as you can with a couple of yes > /dev/null instances running under OSX. If you really want to be sure yours is OK, do this with the Cinebench GPU test running at the same time. I'll be very surprised if it doesn't freeze under those conditions.
In my case at least it seems related to the timing of it all. If you time it so you start the intensive stuff up at the same time while the machine is cool it will almost always be frozen before the fans can hit their max speeds. On my specific machine it is rare for it to freeze while the fans are at max speed.
Edit: This might seem a little extreme so some of you but keep in mind we are trying to reproduce it here. On my machine it will lock up 50/50 just booting up a VM using Fusion so you don't need to be using to the level above to see these issues.
