Hi:

Your notebook was designed that way intentionally.

HP released this document a while back, which explains the memory shortage...

This seems to only apply to some models with the AMD Ryzen processors.

Info on Microsoft PlayReady.

Ok paul but the thing is i am using ubuntu 20.04 on that laptop no dual boot.

and second thing i have got 4x2= 8gb ram installed, can i add one 16gb more to it making it 16+4=20 gb.

Hi:

Yes, you should be able to add a 16 GB chip to one of the 4 GB chips and have 20 GB.

The notebook supports a max of 2 x 16 GB of memory.

Thank you, Paul, appreciate your help.

You're very welcome.

I also answered your other post regarding the memory upgrade in more detail.

Hi Paul

But i am not using microsoft windows, i am using ubuntu.

Hi:

That may be, but the engineering is outside of the operating system, and there is no way to change the memory allocation.

Hi

I installed 16+8=24gb ram and it seems working.

Thank you
