I have an ASUS UX501VW-DS71T, currently with 16GB of RAM.

According with the official documentation at ASUS ZenBook Pro UX501VW about the RAM is indicated the following:

Memory
DDR4 2133 MHz SDRAM, up to 16 GB, OnBoard Memory 8 GB , 1x DIMM socket

Therefore is not possible do an upgrade to 2 x 16 = 32GB. But would be possible do either 8 + 16 = 24GB or 8 + 32 = 40GB. Note: Lets assume is possible do an upgrade until 40 GB

Now, to be honest, since years ago I always have read and listened that is very important have a parity of RAM, I mean: 2 x R such as 2 x 8, 2 x 16, 2 x 32, etc. It for performance reasons and if my memory does not fail me to avoid the OS crash or hang (it mostly for Windows - not sure if Linux can be affected here too)

So far or in this point of time perhaps this situation was fixed due the current improvement of both hardware and software throughout these years.

Question

  • Is safe do an upgrade of RAM but without parity equality?

Currently this laptop uses in peace Windows 10 Home, but in the future is considered to moved to Linux when Windows 10 passes to EOF. And well is used VirtualBox to use Linux as Guest

Of course, the goal is do an upgrade of RAM as maximum possible and have the OS and apps running in peace

Two identical RAM sticks are only required in order to enable dual channel.

Dual channel memory is a technology that allows your CPU to access two memory modules simultaneously, doubling the bandwidth and speed of data transfer.

In your case, as you intend one stick to be much larger than the other, dual channel is impossible. If you could get your hands on an identical memory stick to the existing one, dual channel might be possible with 16GB total, although I must say that I haven't found any documentation of whether this feature is supported by your motherboard.
