Great - Also had the RAM contact problems. What did i do? Got a 1.5mm (.60 cal) piece of flat styrene about 3mm wide and 7 or 8 mm tall, put BOTH RAM sticks in place and with a little plastic tip/spudger push down the stick closest to the keyboard so the clip can make its full travel inward and insert the styrene pieces one in each side in the slots between the clip and where the screws for the bracket are and then push them towards the RAM contacts to make pressure inward so the clips are pressed firmly against the sticks (you wont be able to remove the sticks without removing this styrene pieces). It seem the CLIPS that hold the stick closest to the keyboard are worn and do not have enough pressure so they do not hold the ram in place all the time, a little bump and the RAM stick springs up like half a milimeter and the problem appears. apparently, as i said, and for everyones happines it migh not be the soldering at all!! So I took it apart again, and what did i find. I'm having exactly the same problem as this. I've been reading forums about this problem and after watching this video I have a MBP 15" early 2011, had the logic board replaced in the apple program for the video chip, after that, i started to get kernel errors once in a while, all was pointing to RAM, but could never actually find a defective stick and tried many, after a while of seating and reseating the sticks and a fresh install os the macOs it stopped for almost a year with no problems i thought i was done only to begin crashing, powering off and beeping this week. Hey everyone, after having this problem, i found out the problem might not be the soldering at all. one day there, one day to repair and one day to send it back. Next morning there is an overnight FedEx box on my door step. I call 1-800-MYAPPLE and request it, give them a credit card. Total time for this is four days including the first call day. For that they will fix any and all problems if the machine has not received liquid damage or incurred a major impact. Due to the cost of the part, I have sent two into Apple requesting a "Flat Rate" depot repair. Let's also ask if he has run into The only solution I have found on the GPU issue is a logic board replacement.
This will check both the sticks and the slots. On each try take a look at the system configuration and see if it is reading correctly. Try it in one slot and then the other slot.
To test use just one stick of RAM and remove the other. However, recently I have seen three 2011-2012 machines where it is not and is the logic board. The three beeps has historically been a RAM issue.
