Actually, I can't find a 32GB Kit (16GBx2), 240-pin SODIMM, DDR3 PC3-12800 memory module
Because no one makes 16GB DDR3 laptop DIMMs to begin with...

The Intelligent Memory 16GB SO-DIMM modules are already available, full production.
But the Lenovo/Intel BIOS can not identify them.
The BIOS contains the memory initialization routine, also called Memory Reference Code (MRC), which is a piece of software programmed by Intel for each of their CPUs. This software reads out the parameters from a little Eeprom on the memory module and then sets the registers to drive the memory.
For whatever reason this software can only work with memory-chips with a maximum of 4 Gigabit per IC. This is good enough for using 8 Gigabyte SO-DIMMs, but a 16 Gigabyte module is made of 8 Gigabit DDR3 chips, which the MRC does not know how to handle. The result is that the system hangs when it starts the BIOS.
Lenovo or Intel might be able to fix it and release a BIOS update, but per my information nothing is planned here.

oucha.....Thanks for the technical information, very instructive.
Well it is a bad news news for us on the T430s if Intel or Lenovo does not plan to move in this bios upgrade direction.
I will look and follow bios update than !

Awesome detali, thanks.
I have a T430s and just got the 16GB SODIMM from Crucial (CT204864BF160B.C16FA 16GB DDR3-1600 SODIMM 1.35V CL11 ) and it did not work. I'm on BIOS 2.63 from Lenovo. Anything I can do/check before I return the memory?
