Memory

8 GB DDR4-3200 MHz RAM (1 x 8 GB)

• Dual channel memory architecture (One DIMM per channel)
• Two DDR4 UDIMM (288-pin) sockets
• Supports up to PC4-25600 (DDR4-3200)
• Supports 4 GB and 8 GB DDR4 UDIMMs
• Supports up to 4 GB on 32-bit systems

  note:

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

• Supports up to 32 GB (unbuffered) with two 16 GB DIMMs on 64-bit systems

if so, then it might work
but there is always a risk of incompatibility, and especially with the module already in place..
so, if ever it won't work with both modules, you will have to try the new one alone
if it works on its own, then you will probably have to buy the same one!
But sometimes it won't be a problem, it's quite random
