MacBook Pro 15-Inch, Mid 2012
Processor: 2.6 GHz Intel Core i7
Memory: 8 GB 1600 MHz DDR3
SSD Crucial MX300 1TB
Graphics: Intel HD Graphics 4000 1024 MB + NVIDIA GeForce GT 650M
1680x1050 antiglare display (Non-Retina)
After a system scan on crucial I've bought the 16gb kit on amazon but on OSX 10.10.5 keeps crashing with both dimms.
I ran several Rember cycles for each 8gb dimm on both slots with no issue, the lap works fine. But crashes in few minutes if 16gb are installed.
Thinking the issue might be the dimm itself, I bought a second kit, this time from it.crucial.com. Same issues.
I've contacted the italian IT, they've tried to help me as much as they could but the only solution they kindly offered me was a complete refund (once sent back the kit) and try to buy a Micron updat of the kit (the code 00XXX0 differs from usual .C16FPD in .M16FPD).
Due to the time it would take and digging into the web I found out other users had a SMC 2.1f175 and Boot Rom ver MBP91.00D3.B0C (same SMC ver on Yosemite but the BR was MBP91.00D3.B0B) I tried first a down grade to OSX 10.9.5.
Since I've just finished the downgrade I will update you if this solution works.
UPDATE >>>> Unfortunately even this last attempt failed. I'll be refunded but the point is that this product is not compatible with my mac =(

Number of Processors: 1
Total Number of Cores: 2

Thanks for any insight!

Thanks for contacting us. I pulled up your system and it does appear your Macbook Pro will allow you to upgrade to 16GB of RAM. We would recommend this upgrade for your system:

Hello. Was wondering if I could get some help. I purchsed this:
Crucial 16GB Kit (2 x 8GB) DDR3L-1600 1600 MT/S SODIMM Memory for Mac (CT2K8G3S160BM)
Mid 2012 Macbook Pro
2.6 Ghz i7
Nvidia 650M 1 Gb
I keep getting 3 beeps when I try to turn on with 16GB installed. When I take out one of the cards leaving 1 x 8 GB card in, it boots up fine. When I put in my specs to the site, it shows I should use this:
Crucial 16GB Kit (2 x 8GB) DDR3L-1600 SODIMM Memory for Mac CT3327433
But it's out of stock and I can't seem to find it anywhere. I can't really see a difference in specs from the two memories. Any help is appreciated.

Thanks for contacting us today. CT3327433 is identical to CT2K8G3S160BM, so you shouldn't be experiencing so many issues with this RAM. I am sorry for the problems you've been having. I would advise following this link to see if this solves the issue:
If you are still experiencing issues I would advise contacting us directly using the information in my signature.

Thank you for contacting us. No, this RAM is not compatible with your system. The Macbook Pro 2012 model with the Retina display has memory soldered to the board and is not user upgradeable.
Please let us know if you have any questions or concerns.

i've recently purchased 2 x 8gb memory slots for my 2012 macbook pro based on what crucial said was compatible. I have just installed both yet it shows up that my memory is only 8gb and not 16gb.
does this mean that i've installed it incorrectly?
please see screenshots below?

I have the same system, so was looking to order this upgrade on Amazon, however I don't see that part number listed (CT3327430).
Thanks for your help.
