Has anyone tried two 16gb dimms? I'd like to upgrade to 32gb of ram


Do they exist?  I have not seen a 204 pin SoDIMM for a notebook computer.

I have 16GB of RAM in our T430s.  Those sticks were previously in a T420.

Theoretically if 16GB SODIMMs were available would a T430 (Ivy Bridge CPU) support 32GB? Would a T420 (Sandy Bridge)?

 

I suspect the T430 would but not the T420.

 

Traditionally Lenovo's official RAM maximums are based on what's available at the time the model is announced. For instance I'm posting this from an X61s with 2x 4GB RAM even though PSREF says "512MB, 1GB, or 2GB std / 4GB max31 / PC2-5300 667MHz DDR2, non-parity, dual-channel capable, two 200-pin SO-DIMM sockets."

Hi,

Sorry for digging such an old thread, but can anyone confirm if Lenovo T420 type 4180 Intel Core i5 2520M supports 16 GB of RAM? I have Windows 7 Professional 64 bit
