I just got this laptop . All fine so far , except I find it laggy at times . I plan on upgrading the RAM & add SSD over the course . I see only around 2GB RAM free with normal browsing so first plan to add more RAM . The laptop came with Hynxix RAM and am looking to add additional 8GB RAM .Not really a heavy gamer so not sure if 2666 RAM or faster RAM would matter ?

Im looking at these 2 RAMs

There are mixed opinions about RAM matching and running in dual channel mode . If not any suggested alternatives ? At the moment the crucial one seems more attractive in terms of price .Thanks
