If a dual core processor with GT330M scrapes the TJmax, what more would an i7-2630QM with a Radeon 6750 do with the same configuration?

It's like overclocking with a stock heatsink, expecting it to be all right when it's not.
Heat has nothing to do with the issue. End of story.

Edit: Honestly though. Furmark or Intel Burn Test on OSx would be nice. Everyone's got a different way of "stress testing" that they get inconsistent results everytime.

imagine the heatsink you could buy with 2000$ it would be better then liquid nitrogen

OnTopic: not suprised

Also. That guy, he claims to have set his fan speeds to maximum before running those "stress tests" he was not able to get a crash, lockup, or freeze with Portal(GPU accelerated game) or Handbrake (CPU encoding. Unsure if it utilizes GPU as well.)

All this without a kernel error(which poopascoopa's pushing). If it really were a software issue, then he wouldnt be able to get into Portal at all. He'd have to wait for a fix, as he is unable to use his MBP at all.

FTL1776: Link that video of the guy locking up with just Handbrake.

Also. If it were a Kernel error, that could be the equivalent of a BSOD spurred on by overheating of a component. Let's say, overclock, your OC is unstable. You get BSOD. You hit TJmax, BSOD.

If it were a driver error. On Nvidia, it would return nv4_disp.sys has stopped working, or a BSOD with nv4_disp explicitly listed as the source of error.

Sorry, I'm a sponge...

If you watch the video you posted, you will see the guy said with the normal factory settings it would lock up with just handbrake, but with his settings he was able to run Portal too.

couldn't the theory of MBPs overheating be tested by installing win 7 on the affected machines and doing a stress test?

The crash could be triggered by improperly applied amounts of thermal paste. When the discrete GPU is switched on, it overheats and causes a system hang because of overheating GPU. Apple's heatsink is also smaller than competitors' heatsinks.

Apple releases OS X 10.6.7 with fix for MacBook Pro display issues



It may be a minor update for most, but those with a brand new MacBook Pro will no doubt find the just-released OS X 10.6.7 upgrade particularly welcome. In addition to various minor improvements for all Macs, it includes a fix for early 2011 MacBook Pros that promises to "improve graphics stability and external display compatibility." That sounds like it may actually fix both the freezing issue we reported on earlier today and the flickering issue that's been plaguing Thunderbolt-equipped MacBook Pros since day one, though we've yet to confirm either ourselves. Let us know how things work out for you in comments.

Update: Early indications are that it does indeed fix both the freezing and flickering issues. We'll let you know if we find anything else.

[Thanks to everyone who sent this in]

Time will still tell if Apple truly fixed the issue. Did Apple change the GPU clocks or voltage?

No way of telling for sure, sadly. I dont think GPU-z or HWmonitor exist for Apple. =P
