T470s can't see extra RAM

Hi - I have a T470s that came with 8GB RAM onboard. I've added another 16GB - DDR4 2400MHz - but the computer can't see the extra RAM - it still thinks there's only 8GB.

 

Has anyone else had this problem?

 

Thanks,

 

Paul

Re: T470s can't see extra RAM

What is the spec for the DDR4 RAM that you are trying to use on the T470s? I have 8gb on the planar and an additional 8gb DDR4 module for a total of 16gb. No issues with recognizing the memory, but I am having a mysterious power on problem (AC Adapter boot up only) that is forcing me to replace the system.

Re: T470s can't see extra RAM

Thanks for getting back to me. Some more info: my colleague had the same problem, trying to add a 2400MHz RAM chip into a brand new T470s - we believe this is the correct RAM for this machine. However, it worked for him when he tried it with a 2133MHz RAM chip, so it looks like that's what I'm going to have to do. 

 

Can't help you with the boot problem I'm afraid - that's not one we've come across.
