Pros: Nice notebook for the money. Came with 4 GB of memory, has a hard time finding upgrade memory. Took a chance on the Acer chat site, here is the actual chat message: Helika Sumi: Michael, thank you for being on hold. I appreciate your patience. Helika Sumi: I have checked the information for you. Helika Sumi: As per our resources, your computer is upgradeable up to 16GB SODIMM DDR3 1333/1600. Helika Sumi: It has 2 DDR3L Socket. Helika Sumi: The Support DIMM voltage is 1.35V. Michael Dunn: I purchased the notebook from Newegg and it says the max is only 8 GB. just want to be sure before ordering more memory. Helika Sumi: The support memory size per socket is 2GB/4GB/8GB. Helika Sumi: The maximum memory is 16 GB. I took a chance that the chat was correct. I ordered G.SKILL Ripjaws Series 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1600 (PC3 12800) Laptop Memory Model F3-1600C9D-16GRSL from NewEgg. The laptop does support 16 GB of memory. Initially I put in both dimm's and the laptop didn't boot up. Took one dimm out and the laptop booted up without any problems. Powered down the notebook and took the 8GB dimm in the right slot and move it to the other slot and then inserted the other 8GB dimm. I'm kind of impatient and I believe it just took a while for the BIOS to recognize the new memory. My notebook running with 16GB of memory without any problems. loving it!!!

Cons: Didn't come with an internal DVD R/W optical drive, but my USB DVD drive works fine.

Overall Review: Had no problems upgrading to Windows 8.1 (free upgrade), also downloaded a nice utility called "Classic Start" that give you a start button in windows 8 for people like myself who still like the windows 7 start button feel,

Pros: Great Price

Cons: Didn't read the features of this memory. States: Designed Specifically for Socket LGA1156. Will not work in a Socket LGA1155 motherboard. A important little piece of information I forgot to read when I ordered this memory. Now I have to return and get new memory, thought I was going to have a computer to play with tonight. The sad thing about this is the ASRock H67M motherboard - memory support list on their web site states this memory is supported on this motherboard.
