Do DDR3 SODIMM modules come in sizes greater than 8GB?

Question

I'm really interested on buying a 1x16GB DDR3 SODIMM module because my laptop has only one memory slot. I know that DIMM modules with 16GB do exist. But I can find only packs with two 8GB modules of SODIMM. So, where can I find such a module if it exists ?

The laptop I want to upgrade is an Asus UX32VD with 2GB of DDR3 memory on mother board (can't change it), and 1 slot. I upgraded it to 10GB (2+8).

Solution

Yes, they only recently did.

However, if you are using an Intel processor from 2013 or earlier then you may not be able to utilize 16GB sodimms.

The only exception is the Atom C2xxx series Avoton.

The i3, i5, i7 Sandybridge, Ivybridge, Haswell processors all can take only 8GB UDIMMs or SO-DIMMs.

Not sure about the latest generation of Intel processors though.

On AMD platforms, the Intelligent Memory 16GB modules are said to work fine.

It generally is not the processor, but the BIOS/Chipset/Firmware that limits the addressable size of memory module.

Given that the memory controller is 'on-die' of most modern processors, it is now the main factor that limits any memory sizes.

@David: In the case of Intel processors, it is the MRC code in the BIOS that needs to be updated to support 16GB unregistered DIMMs.
