I'm trying to upgrade Lenovo B50-80 with another 4 GB RAM stick. First I made sure to buy a stick compatible with the one I have installed. After upgrade my BIOS and OS still show only 4 GB of RAM, while CPU-Z, and RAMMon for instance show 8 GB (both sticks). Also 4 GB is not an OS limitation, I have a 64bit OS. Also, I have tried booting with just my new stick, and in either SO-DIMM slot, and it doesn't work. On the other hand, RAM stick I got with the laptop works fine in either SO-DIMM slot. I have attached the output of RAMMon (RAM analyzer software), where the program is detecting the newly added RAM stick.
This is RAM stick I got with my laptop - https://www.amazon.c...ology PC3-12800
This is the one I bought to upgrade - https://www.amazon.c...gston PC3-12800
Is the RAM stick faulty, or can I try something else? Any help would be greatly appreciated.
