Hope all is well.
just 1 question
Does md103ll/A logic board fits mc723ll/A ?!
i dont want to buy a new logic board wich i know will fail after months again ... hate amd geaphics they overheating issue is always there since intel pentium
Greetings From Egypt

May 22, 2014 4:44 PMby DMC440,I accept that dust and “environmental factors” ultimately cause the failure of these machines in the same way that everyone dies of cardiac failure, but that is no indication of actual cause of death.
I also accept that dust can been found under the solder of the GPU BGA.
The problem is, why does it get in there? And the answer to that must relate to shortcomings in the overall design of the machine.
The problem machines are predominantly early-2011 15” and 17” MacBook Pros. The 13” model aren’t being reported which would be because they do not have an additional discrete GPU.
The problem machines are the first MBPs to be based on 32nm Sandy Bridge architecture and the first to use AMD Radeon discrete GPUs. Sandy Bridge runs hotter than previous chipsets. Anecdotal evidence suggests the 6750 Radeon also runs very hot (some PCI cards have been reported for this).
The predecessors (Mid 2010) ran NVIDIA GT330M discrete chips and Penryn-based chipsets. No long forum threads listing premature deaths there.
The late 2011 models occasionally throw up the issue but they are running a different GPU, for one. And perhaps they got the cooling sorted.
The successors (mid 2012) use the 22nm Ivy Bridge architecture. Now, while this is reputed to inherently produce less heat - as they draw less power - they actually run hotter due to the smaller size. Again, maybe they learned from our machines that better cooling was required. Interestingly, the machines also went back to Nvidia discrete GPUs.
The problem machines are also the first MBPs to be assembled with lead-free solder with all its shortcomings.
If dust is easily accumulating and impeding the cooling system that must also be considered poor design.
So ultimately it feels like this generation of machine should never have been released.
I’m happy to be contradicted on any of the technical detail here.
I’d also like to hear from anyone who can identify another single generation of machine from any manufacturer that is reporting such significant numbers of failures.

How about the late 2007 MBP (last pre-aluminium generation) with NVIDIA GeForce 8600M GT graphics processors ? Similar story - only that Apple issued a replacement program ... after numerous failures.
Took a while though until they came up with it....

Anyway guys, the real problem is not the GPU but rather it is the heat of the CPU to be too high. If monitored temperatures you will find that all the other components have temperatures that are normal. Rendering high-quality video raises the value of cpu to 90+ degrees but the GPU temperature is usually about 64 degrees maximum during this. So the real problem is the CPU that going to deteriorate the GPU. And this has always been there! Try to look for articles on the release of MacBook Pro in February-March 2011 and you will see that the problems were initially only system crash for overheating. But now the problem has become much more serious. Then I repeat again as I did in another post that Apple delayed the release of MacBook Pro early 2011 for this reason. Now they should remedy the problem that is already known from the first moment!
Please stop posting nonsense when you have clearly no idea what you're talking about. This CPU is rated for a maximum operating temperature of 100°C and it will automatically throttle when it reaches the point. While it is not a good thing that it might get as hot (semiconductors age faster when they're operated at high temperatures) it is a known fact that the problem here is not caused by overheating but by physical damage at the soldering level -- to the GPU, not CPU.

I see here suggestion to upgrade the GPU while at it, and to be sure that a reball has been done.....
but as far as i know you can't upgrade the GPU?
even with reballing?

Why not upgrade ? Same motherboard, same AMD GPU series, same pinout. Upgrading to a 6750/70 should not be a problem at all since they were available for the 2011 MBP.
Strange: this was the response of a official Apple Premium Service Provider "Not Possible"....would like it to have it verified?

They didn't "came up with it" but were forced to it due a class action suit.
Just as they were forced, with fines, even threatened to be banned from selling in some countries, like Italy, to give a real 2 year legal warranty in Europe.
They really did everything they could to keep it to a 1 year only warranty....
If you look into it all, Apple isn't that "premium" for me.
Only premium money grabbers they are....
