The issue is that I have a Bangho brand notebook (Argentina) that has the following mother: W130EW, manufacturer clevo (source: https://www.clevo.com.tw/clevo_down.asp?lang=en)
Its specification says that it supports 8gb but when I use the command wmic memphysical get MaxCapacity, MemoryDevices it tells me that it supports 16gb.
So what is my actual memory capacity?

wmiccommand assumes that you have all the memory channels available along with multiple DIMMs on each channel. It is the processor maximum. Most commercial processors have 2 channels with 2 DIMMS per channel. Your motherboard manufacturer may not have wired up multiple channels or DIMM slots and if you can only fit 2 DIMMs (when the processor supports 4) then you will have half the memory capability. – Mokubai Jun 09 '22 at 19:54
