Maximum memory for an HP 3047h Motherboard

A family member said a Windows 10 system she is using for gaming is running slowly and inquired about adding additional memory to the system. I didn't know the model of the motherboard in the system nor the maximum amount of memory it could accomodate. Rather than opening up the desktop system, I checked on the manufacturer and model of the motherboard from a command-line interface (CLI) with a Windows Management Instrumentation Command-line (WMIC) command and found it was a Hewlett-Packard (HP) 3047h motherboard.

I also saw 3047h listed as the "baseboard product" ("baseboard" is another name used for "motherboard") when I typed System Information in the Windows "Type here to search" field and selcted that application.

System Information - HP 3047h

Specifications I found for the motherboard at Hewlett-Packard 3047h Mainboard Specs showed the motherboard could accomodate 4 DDR3 memory modules in 4 DIMM slots for a maximum of 16 GB of memory.

And checking details for the memory modules with a WMIC command showed that the 4 memory slots were occupied by four 4 GB DDR3 memory modules (MemoryType 24 signifies DDR3 SDRAM).

So I realized I will need to replace the motherboard to increase the memory in the system since the motherboard installed in it can not accomodate any additional memory.
