Laptop question, RAM

[Bisto 17]

Hi,
https://www.amazon.com/Acer-Flagship-Performance-i5-7200U-Dual-Core/dp/B01M5G7EQ3/ref=sr_1_3?s=pc&ie=UTF8&qid=1485709564&sr=1-3&keywords=i5+ssd+laptop&refinements=p_n_feature_four_browse-bin%3A2289793011%2Cp_n_feature_two_browse-bin%3A610553011%2Cp_n_feature_five_browse-bin%3A7817224011%2Cp_n_feature_twelve_browse-bin%3A9521908011%2Cp_n_operating_system_browse-bin%3A12035945011%2Cp_n_graphics_type_browse-bin%3A14292273011

I found this laptop on amazon.com and it looks quite interesting, but i have a question about the RAM?
The title says it's DDR4 8GB RAM but if you look in the technical specifications, it says "Computer Memory Type DDR3 SDRAM"
Now i'm no idiot with computers, but is this tellling me that the ram is actually DDR3 and not DDR4? and they're being naughty by advertising it wrongly?

thank you

Advertising mistake can be made, intentionally or not. Manufacturer's manual is Godspel.

It's an advertising mistake. The laptop uses DDR4 RAM; likely a single stick of RAM. Below is a link to Acer's website for that laptop.
