Identify MacBook Pro logic board, presumed to be 15" Early 2011

I have searched for hours and hours to find a solution, but I cannot identify this logic board! Could someone please help me? I really need to figure out which processor it has, in addition.

On the RAM slots:

(small sticker) CI3A 21PWIMB04Z0

(sticker with bar code) C021495037NDYN4A2

^ from this I gathered that the EEE code was "DYN4"? But even then, I can't look it up with the Ultimate Mac Lookup tool.

Logic board number: 820-2915-B

I've seen that part number lookups exist too, in the XXX-XXXX format, but I can't find that either.

I would be so grateful! Thank you.

15" MacBook Pro (Late 2011) 2.4GHz Logic Board

Apple MacBook Pro "Core i7" 2.4 15" Late 2011 Specs

Identifiers: Late 2011 15" - MD322LL/A - MacBookPro8,2 - A1286 - 2563*

Brian, while there have been some failures of the dual GPU set up on this machine, I believe Louis is greatly exaggerating the issue. From Wiki: n August 2014 the law firm Whitfield Bryson & Mason LLP had begun investigating the problem to determine if any legal claim exists.[77] On October 28 2014, the firm announced that it has filed a class-action lawsuit in a California federal court against Apple. The lawsuit will cover residents residing in both California and Florida who have purchased a 2011 MacBook Pro notebook with an AMD graphics card. The firm is also investigating similar cases across the United States.[78] Apple, as of mid-September 2014, refuses to comment on the issue.

Just as the earlier nVidia 8600 GPU had a class action law suit, not all of them failed. I do have a stack of the older machine with failed boards but there are many, many others that are still running just fine. If you feel you have a failed board, I would contact Apple first and see if they will repair it for free (if nothing else, have the request on record). Ask for a "Warranty Exception", Apple knows they are facing a law suit and may just fix it for you. That failing, I would request a "Flat Rate repair from them and send it in for a Depot Repair (total time 4 days), if you do not live near an Apple retail store. The cost is around $320. Then keep a watch out on the results of the law suit. If it succeeds, then you can request a refund from Apple.

I would be interested to see what Louis thinks of this resolution path.

+ Informative answer, well researched. On a side note: Law firms such as Whitfield Bryson & Mason LLP make their living pursuing/investigating "problems" to determine if any legal claim exists, aka Class Action Lawsuits. They take over 50% of the coffers when they get a positive result. Leaving little compensation for the parties that were damaged. Because these attorneys know they stand a chance of losing, most of those cases are settled, allowing the defendant to deny problem existed. Rarely are they ever tried on the merits.


I appreciate it, mayer, you nailed two birds with one stone in your answer - thank you!


Cellers, I do not advise joining the suit. All we want is a working Mac. But after the 8600 law suit, Apple did, on most occasions, do the repair for free, albeit for only 4 years. (It wasn't actually paid for by Apple but by nVidia). I, personally sent in about a dozen of them for myself and my customers for free repairs. Once Apple admits there is a problem they have been pretty good about doing the repairs. I'm currently seeing this on the 2011 27" iMacs with bad GPUs. (But I don't see it on their recall list, you have to know about it.) mThat is this list:


Mayer, I apologize if I did not articulate my thoughts well. I don't believe you are or would promote joining litigation against Apple. I was actually, in my own way, expressing that most of these lawsuits have little merit. Backing you up, that the problem maybe not as prevalent as some people would like to believe. I pay attention to what you have to say on issues such as this. I believe you are more informed "on the real world" of them than the hype others wish to be.


Thanks Cellers, All i really want is for people to have their machines work as they were intended to do. I believe Apple should be more prompt doing what AA says: Step 10 "Continued to take personal inventory and when we were wrong, promptly admitted it.."

I don't understand, it is an 820-2915 which makes it a 2011 logic board for an A1286 machine.

Which, being 2015, should have a dead AMD GPU by now since it shares a heatsink with a quad core, sandy bridge processor.

Thanks. I didn't realize there was an overheating issue for these.

Can you tell the processor from that info? That's the main point of confusion.


All 820-2915 are quad core i7, sandy bridge architecture, which combined with the AMD 5770 you can cook a thanksgiving turkey on.
