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).

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.

An example Haswell:

https://ark.intel.com/content/www/us/en/ark/products/78939/intel-core-i7-4910mq-processor-8m-cache-up-to-3-90-ghz.html

  • Max 2 slots
  • Max 32 GB (I assume that's 16 GB x 2, not 32 GB per slot)
  • 1333 or 1600 DDR3L/PC3L (L is low power version, is low voltage)

Side notes:

DDR3L is 1.35V low power, regular DDR3 1.5V

On my laptop I know that regular DDR3 non-low power works. So the processor can do 1.5V. And I've subsequently A/B tested both DDR3 and DDR3L across 4910mq, 4810mq, 4710mq and others across several HP J series motherboards and a Clevo w650 motherboard. It's clearly supported in actuality electrically, though its not on the spec sheet. So at your own risk. 1.5V in most cases is slightly faster. I hit these very very hard with testing and real loads over long periods.

I've never tried 16GB module, but I stumbled across this looking to buy a 16GB module. Wanted to share what I knew for future travelers. If I buy one I'll report back.
