32 GB RAM UPGRADE on a MacBook Pro, Mid-2012
THESE ARE THE ORIGINAL SPECS:
This 15-inch Mid-2012/USB 3.0 MacBook Pro 9,1 features a 22 nm “Ivy Bridge” 2.6 GHz Intel “Core i7” processor (3720QM), with four independent processor “cores” on a single silicon chip, a 6 MB shared level 3 cache, 8 GB of 1600 MHz DDR3L SDRAM (PC3-12800) installed in pairs (two 4 GB modules), a 750 GB Serial ATA (5400 RPM) hard drive, an 8X DL “SuperDrive,” dual graphics processors -- an NVIDIA GeForce GT 650M with 1 GB of dedicated GDDR5 memory and an “integrated” Intel HD Graphics 4000 graphics processor that shares system memory, as well as an integrated 720p FaceTime HD webcam.
After purchasing it, I put in 16 GB, and it works great. From experience, it can significantly improve my speed when running concurrent tasks.
Can anyone tell me if there are any compatibility issues with this upgrade?
I have yet to be negatively forewarned; specs show it will handle 32 GB, which I will purchase if I don’t hear anything from you all!
