Hello.

 

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.  

 

Thank you!

Hi,

 

I think the problem is the voltage, the laptop only accepts 1.35V modules and your new module needs 1.5V to work.

 

Using the Kingston memory search it only lists modules that work at 1.35v

and the same with Crucial
