The machine:
late 2011 15in MacBook Pro
i7 Sandybridge 2.2 GHz
8 GB/8 GB (1333MHz,DDR3) = 16 GB RAM
Intel HD graphics 3000 512MB

The background:
I have had this Mac for awhile now. I have dropped it twice now and both pretty hard times (dropped open). After this I started to notice kernel panics initially when I would open up a folder full of pictures. This continued and El Capitan was released so I figured I should just wipe it clean and start fresh, thinking the problem might be software related.

After initially just installing the new OS over the existing one(leaving all my previous data intact), I finally just decided to wipe it clean and do a fresh install. This was complete and I thought that I might have solved the issue.

I started to experience more and more frequent KPs yet still no predictable schedule to when they would occur(some a hour apart, some ten minutes). At this point I started to look into the hardware side. I ran AHT (both sticks of RAM) and I got a 4MEM/60/40000000 error = memory module.

Once the error pointed to my issue I then began to open up the MBPs' backplate and preceded to reseat the memory in hopes of a simple fix, which did not work. I then tested each stick separately and in each respective bank. The results were as follows:

bank/dimm01(lower)  
stick A = no error  
stick B = no error  
bank/dimm02(upper)  
stick A = 4MEM/60  
stick B = 4MEM/60  

I figure at this point that the bank/dimm02(upper) slot is bad (probably damaged from a drop of something similar).

I take stick B seat it into bank/dimm01(lower) and boot it off one stick. Just to be extra sure I ran rember too and it came back clean. Finally I thought the problem was 'resolved'.

24 later, on the single stick boot, guess what? another KP and not just one, a nice and lovely triple kick of repeated KP for my holiday splendor.

Does anyone have any insight? All info is appreciated.

Looks like a Graphics crash from this…

panic(cpu 0 caller 0xffffff7f837c350e): "AGC GPU REGISTER RESTORE FAILED : rdar://7254528, VendorID invalid"@/Library/Caches/com.apple.xbs/Sources/AppleGraphicsControl/AppleGraphicsControl-3.12.6/src/AppleMuxControl/kext/AGCPowerManagement.cpp:1158

I'd check with Apple whether you have one of the machines with a known problem -
MacBook Pro Repair Extension Program for Video Issues

  • Even if this isn't a covered repair - flat rate $300 rework of all the parts that are bad isn't that costly when you consider trying to buy used logic board and swapping it yourself. – bmike Feb 17 '16 at 1:42

The machine was taken to Apple, and test were ran to see if it qualified for the repair extension program, it did not.

I've ran a few other sticks of RAM in the Dimms but to no avail, still random KPs. I'm supposing at this point that it is something with the logic board, memory controller... and at this time weighing my options accordingly.

UPDATE: The machine is being repaired at apple, new logic board.

Thanks for all your insight cheers
