Lenovo G500 RAM Upgrade Issue

Hello there,


I own a Lenovo G500, a 2013 model, and I just bought a 2 x 4GB 1600 MHz Kingston HyperX DDR3L memory kit.

I pulled the old 4 GB memory out and put the new cards in, but both my Windows 7 and the BIOS see only one of them, so the laptop only uses 4 GB of RAM.

I tried putting the cards in one by one, the bottom slot works, but when I only use the top slot, the laptop does not boot. It's likely this is the problem, cause even CPU-Z only sees RAM in one of the slots and displays "Single Channel" running.


My question would be: is there a possibility this is a software issue? Is there a way to enable dual channel?

If not, could this be a motherboard issue?


Thank you.

Re: Lenovo G500 RAM Upgrade Issue

Hi blender917 , 


Welcome to the Community Forums. 


Memory specifications:

Up to 16GB DDR3- 1600Mhz(Support Dual Channel) [2 SODIMM slots (1x2GB/2x2GB/1x4GB/1x2GB+1x4GB


Would the working Old stock RAM or new Kingston from the bottom slot work alone if fitted on the top slot?

The top slot should be able to be detected by both BIOS and WIndows.


As so it may be more of a hardware issue on the board.

You may check  on the slot itself if there are any particles preventing contact maybe using a compressed air can.

Make sure that it fits securely. Try using the old ram on the top first .


Would both new ram work ok on the bottom slot ? 


Update us how it goes.
