Q: 2011 MacBook Pro and Discrete Graphics Card

You must get the last word in or your not satisfied.

I am a retired Test Engineer who has setup printed circuit board production lines, designed the devices for determining proper functioning, implemented production process changes and produced production, in more than one country, with over 98.6% plug and play.  When companies had a problem they called me, I didn't call them.

If you think its rational to achieve the highest reliability by using used parts, good for you.

No less rational than claiming to have the fix for 90% of Macs with these symptoms.

I am not a Test Engineer.

That's your choice of course, I doubt that 90% of all failing Macs were repaired that way but, only time will tell.

 

Good luck.

For any machine or device 80% of the problems will be caused by three parts, workman ship being defined as a part for this discussion.  Go to any repair shop of any kind and check for your self.

When the problem is process like this one, common materials are a part.  In this case we are highly suspicious of the solder joints on one part.  Therefore the solder is not the problem, nor is the temp of solder process.  The problem is narrowed to placing the solder.  If the registration is off in one area of the printed circuit board the problem would be repeatable, as is the case with GPU chip in question. 

One than needs to ask if just re-heating will improve the registration of the remaining solder on those failed pins?  If good enough for government work is good enough for you, re-heat and wander on.  If you need a high degree of assurance than you might need another choice.

And it shows

Why would I need "another choice" my Macs (even the 2011) run fine, no overheating (yet) even for the ones that are on 24/7

So I won't need another choice thanks

Oh, who's we?

iI was replying to Csound1, not to you.

Probably hit the send button just after you did.

I was not disputing your statement, as in theory, you are right.

Sorry... I did notice your name after I sent the message and was puzzled by it.

"Test Engineer"

Would that be one who starts his post with (completely unsupported and unsupportable) statements such as "90% of all failing 2011 MBPs can be repaired by replacing one, still working GPU chip"

Got something to back that up or shall we leave it in the "opinion" box.

But you are right, I am not that kind of engineer.

I am married.  Habits have momentum... what do you think will be your last word this time?

since nobody knows what you're doing with your (so many) mac computers, it doesn't prove a thing they're running fine 24/7, even for your so-called-just-bought 2011 mbp.

and since you're trying hard to show how clever you are, guess you know the difference between having one and only computer used 24/7 and seven of them, if not more for you.

maybe all your computers are just powered on and doing nothing, maybe you just truly using one, maybe you don't even own any mac product, maybe you're a girl, who knows since 'people' can say whatever they want on the internet, right?

I'll let you choose.

Go back to the first page and read every entry, make a list of all reported problems and a list of all problems fixed by the re-solder or replacement of the GPU chip.  What is the percentage you get?

While your at it  here is a elementary school math question from 1877 that was part of no paper no pencil test.  See how you do.

2. A boat worth $864, of which 1/8 belonged to A, 1/4 to B and the rest to C, was lost: what loss did each sustain, it having been insured for $500?

I just bought the 2011, they are relatively cheap and I did not have one. I am pleased how well it runs for a bargain Mac.

Believe whatever you choose, it makes no difference to reality.

I am not your researcher, you want real data then you gather them, after all, you are the 'Test Engineer'

The loss is conditional upon the insurance payment, which you did not specify.
