hey,so i have an ASUS x555Lb laptop whic has a 4gb of ram installed on the motherboard already,its all godd but when i add my 4gb of ram to an free ram socket the pc only reads the 4gb of ram which i added.My laptop ony reads motherboard ram or the ram i put in the socket,doesnt read the both at once.When i add my ram then motherboard ram just dissapears,when i take it out then the motherboard ram works fine.What could the problem be?
Thanks in advance,
