“Some of the posts and Q&A state the RAM can be updated. Others say "no". It appears that you can add 8GB DDR4. Once suggestion was 8GB DDR4 2133. I don't see this size available on BestBuy.com. Can DDR3 be used as an alternate?”

2 RAM slots are featured. Upgrade with 8GB DDR4 2400MHz [laptop]. This will match existing 8GB chip. Comes with Samsung made chip, some made in China while others are made in Philippines. Standard chip serial number is typically M471A1K43CB1-CRC - 8GB PC4-2400T-SA1-11.
Sorry, there was a problem. Please try again later.No, as the Different "levels" of DDR are vastly different, DDR2 is faster than DDR, DDR3 is faster than DDR2 and DDR4 is faster than DDR3, part of it is the physical shape of the RAM, but it is not a good Idea to mix and match them, I would take a look at Ebay or amazon to find ram, Newegg is also a good option!
