What RAMs would be compatible with the existing 4gb 2400mhz stock fit?

[Adwith]

Using-but windows 10 hp slimline  270-p0xx which comes with a 4gb 2400 mhz stock RAM. Was looking forward on combining it with a crosair or adata 16 gb 3200mhz ram. Would it function together seamlessly?

@Adwith Welcome to HP Community!

I understand that you would like to upgrade the memory.

I have checked the specification 

Memory upgrade information

• Dual channel memory architecture

• Two DDR4 UDIMM (288-pin) sockets

• Supports up to PC4-19200 (DDR4-2400)

• Supports 2 GB, 4 GB, and 8 GB UDIMMs

• Supports up to 4 GB on 32-bit systems

  NOTE: 

  32-bit systems cannot address a full 4.0 GB of memory.

You could purchase the part from HP, use the HP Parts surfer to identify the part: http://partsurfer.hp.com/search.aspx 

And order it via the HP Parts store: https://parts.hp.com/hpparts/CountryChoice.aspx?mscssid=&ccode=ZZ&lcode=ZZ 

Or alternatively, Contact HP for setting up an order/service via phone support
