Make sure that your motherboard’s BIOS is up to date, along with any updates for your operating system. Also, look at each RAM stick individually to make sure that they are indeed exactly the same. If one of them looks inferior for any reason, you could consider replacing it. My laptop has a cheap factory 4GB SDRAM stick and a better 8GB SDRAM stick that I purchased as an upgrade. They both work together, and it doubled my laptop’s speed while enabling more browser tabs, etc. to be open at the same time. Get to know your computer’s motherboard, it’s capabilities, your RAM details, and any drivers or software that could be useful. Good luck! I hope this helps.
