Q: 2011 MacBook Pro and Discrete Graphics Card

May 18, 2014 3:24 PMby Xyclade,Oh some dutch movement going on? You can count me in in case you want to start something.
Btw on a side note, my MB pro runs when using integrated only, but unfortunately I use a lot of tools which override the GFXStatus, like just now again.
I got fed up and carefully opened up, and took out the logic board. In complete contradiction with what PS3Specialist said I didnt find a grain of dust, but what I did find was the heat sink screws being rather loose. I could give them 1.5 complete turns with a screwdriver without any force what-so-ever.
After that I put it back together, and turned it on, and of course still the gray screen. But after clearing the nvram it booted up, and it actually didnt crash when it turned to discrete graphics.
The question ofcourse is... How long will it last...

May 18, 2014 4:29 PMby DMC440,XCylade - which programs override the GFXStatus? I'm yet to see that. Since getting my machine back with a replaced logic board, I've been keeping careful note of which applications invoke the discrete GPU, shutting them down, forcing Integrated only via GFXCardStatus, and then reopening them. So far, none have overridden and switched to discrete.

Utilities with the ability to force the use of either the integrated or discrete graphics may not always allow for better battery life and are not recommend by Apple.

Did you replace the thermal paste?
If it is running fine now would really consider doing that.
Get yourself some Arctic Silver CERAMIQUE 2. Apply it sparesly.
Might run a lot cooler and with a bit of luck, who knows how long...
Before I get commented, prefer ceramique 2, as it doesn't dry out like AS5 does.
And if there is a difference at all, it might only be 2c.
Sometimes in favor of AS5, other test the ceramique 2 might be 2c lower.
Hope it helps you.
Btw, I'm not Dutch, but from the Dutch speaking neighbor country .

May 18, 2014 7:44 PMby Ryan Connolly,Got a 3 month warranty which ended about a month ago - assumed the guy knew what he was doing - maybe not! I'm wondering whether he didn't replace the origin chip? Not too sure how it works, how can i make sure I'm getting a good deal next time, and also, can it even be done twice?

May 19, 2014 12:44 AMby mixoita,another victim from italy! apple is not synonymous with reliability but thieves! and the so-called Apple Store technicians are trained monkeys! unfortunately the quality has dropped too much and not worth the trouble to be loyal to a brand that is expensive and does not care about more than the satisfaction of his customers!

May 19, 2014 12:55 AMby fredrik1977,for me is the same in italy, i've checked 2 different technical services and they denied the existance of this fault in MBP early 2011. Still when i sent them the links to this topic they stated that's only misfortune of few users. not sure if it's stupidity or censorship.

May 19, 2014 1:11 AMby lindensmith,Another Late 2011 MBP that just started having GPU problems. The problems just started showing up thursday or friday of this past week when I connect an external monitor (which is my normal operating mode). Now, using gfxcardstatus, it's verified that it's due to the discrete GPU. If I force it to integrated only, it runs just fine. If I leave it in dynamic switching, the screen goes crazy shortly before the machine hangs. I just installed hardware monitor today, and on one of the crashes since then I saw a temp spike on the GPU (~120 C) just before the crash. I haven't been running hardware monitor long enough to have good data on that.
