Thinkpad T420 16GB Memory Upgrade

[ Edited ]

I want to upgrade my Thinkpad T420 to 16GB, however, the memory advisor only shows 8GB(2x4). How can I find what 2x8 memory modules work in the system?

 

I know that initially the system was only certified for 8GB max but the Intel i5 has been proven to handle 16. Looks like it takes DDR3-10600, 1333MHz.

Hi Greywolfe49,

 

Yes, the part number you referenced CT2KIT102464BF1339 matches all the specs of your system. We haven't done any testing on our end so we can not guarantee the compatibility, however. If you happen to purchase and have any issues we do have a 45 day return policy. Please let us know if you have any other questions or concerns.

FYI, just installed this memory and all 16GB show up in system and works fine.

Re: Thinkpad T420 16GB Memory Upgrade

It's Jan 2017 and I want to upgrade my recently purchased Lenovo T420 from 8GB to 16GB RAM.

I searched for the 16GB memory upgrade kit ( CT2KIT102464BF1339 ) identified in this thread and the kit no longer exists on crucial.com.

What is the replacement equivalent of CT2KIT102464BF1339 or is there a better choice of 16GB upgrade kit for the Lenovo T420?

My T420 is the Intel Core i7 2640M version.

 

Thanks,

I got the same problem. I just purchased a Thinkpad T420 with the same Core i7 version. It'd be helpful if you tell me whether you found out the way to up to 16GB of RAM.

 

Thanks,
