Silicon Power Hynix IC Compatible for Apple DDR3 DDR3L 16GB (2 x 8GB) RAM 1600MHz (PC3 12800) 204 pin CL11 1.35V Non ECC Unbuffered SODIMM Laptop Notebook Memory RAM Module Upgrade

Easy to install and had ZERO compatibility issues with the Lenovo Thinkpad W550S!

I used this memory to upgrade my Mid 2012 Macbook Pro. It was painfully slow to get anything done before, even something as simple as opening a pdf file. Now I can multitask and run programs seamlessly and 10x faster than before. I dont run any processor heavy applications but I do need to get things done in a timely fashion when I do use my Macbook, and this memory upgrade is definitely is the reason Im able to get things done now.

The product is amazing and price too.

Installed and works like a champ

Highly recommended!!

Great price and works great -- all 16 GB available...

The 8GB memory stick was perfect for my Dell 15 5555. Added this to existing Ram to increase capacity - works well no compatibility issues

Works great on 2012 Mac. Cheap upgrade and lots of performance for the price.

Installed easily and now iMac is running like a new computer! Loads much faster, no spinning beach ball even when running multiple programs (even some adobe products at once). Well worth the money!

Installed this 16gb ram on my MBP 2012 two weeks ago. It was fine until last night where my start up screen flashed the prohibitory circle. After running the repair disk utility, the MacHD drive was replaced with Disk0S1. The partition map efi was corrupted etc and will not boot up and needs to be removed.
