    Check the documentation for you motherboard. – SiXandSeven8ths Nov 18 '16 at 17:02
  • There are too many answers to this question and all of them depend on whether it is a desktop or laptop, what processor is fitted and what the manufacturer decided to wire up. – Mokubai Nov 18 '16 at 17:27

These would depend on your motherboard.

On Unices, commands such as dmidecode would help you identify what hardware you're working with. Without knowing such, we can't tell.

Not being familiar with Windows, I can point you to: How can I find out what motherboard is in my computer?

As of Z170-A, you would find the exact specs on Asus website (https://www.asus.com/Motherboards/Z170-A/specifications/). As suggested already in the comments, it is limited to 64GB of DDR4.

  • This is correct, different motherboards have different chipsets that can have different values. Modern computers from 2015 and up can handle 8GB RAM per slot, exception would be small tablets and netbooks. – Peter Nov 18 '16 at 17:13
  • @Peter how about ASUS Z170-A motherboard? it has 4 slots and support 64GB !! – hossein safavi Nov 18 '16 at 17:48
  • If it supports 64 GB, the logical conclusion here is that each slot can use 16GB modules. I haven't seem 16GB sticks in stores, only online and very expensive. – Peter Nov 18 '16 at 18:04
