I have an extra 8 GB of memory on one chip left over from a team update. I know it'd fit inside a co-worker's laptop, but she currently has 16 GB and her computer only has two slots.
She's extremely busy, and our team lead, and I don't want to take apart her computer just to find I can't do anything. I'd like to have her look up what she already has before I raise her hopes. She's on Window's 10.
In addition to answer provided by Dark Matter I found a command line tool.
You can run the cmds natively in Command Prompt.
Or you can run the cmds as follows in Powershell.
PS >
cmd.exe /c "wmic MEMPHYSICAL get MemoryDevices, MaxCapacity"
cmd.exe /c "wmic MEMORYCHIP get BankLabel, DeviceLocator, Capacity, Speed, PartNumber"
Command: wmic MEMORYCHIP get BankLabel, DeviceLocator, Capacity, Speed, PartNumber
C:>wmic MEMORYCHIP get BankLabel, DeviceLocator, Capacity, Speed, PartNumber
BankLabel Capacity DeviceLocator PartNumber Speed
ChannelA 8589934592 Bottom-Slot 1(left) M471A1K43BB1-CRC 2133
C:>
I can tell that I have 8 GB in 1 slot... 8589934592 bytes = (8589934592 / 1,073,741,824) = 8 GB
BankLabel column will tell you which slots the RAM chips are installed in. Capacity columns will tell you that how large each module is expressed in bytes. DeviceLocator is another entity to tell which slots the RAM chips are installed in. The PartNumber is the exact part you have installed; You can look up this part number online at your favorite parts store (Amazon.com, Newegg.com, etc), and find more specs there.
Command: wmic memorychip list full -- For full list of memorychip data fields

Furthermore, use the following command to display the Number of slots you have on your motherboard and the Capacity for each slot.
Command: wmic MEMPHYSICAL get MemoryDevices, MaxCapacity
C:>wmic memphysical get MemoryDevices, MaxCapacity
MaxCapacity MemoryDevices
33554432 2
C:>
MaxCapacity is in kilobytes, so on my computer it is 32 GB max capacity per slot... 33554432 / 1,048,576= 32. That is 64 GB total max capacity.

Credit: Command "wmic memphysical get maxcapacity" gives wrong number
Two better answers:
1) Go to the dos command line ("cmd") and enter: "wmic memorychip list full"
2) Task Manager, Performance, "Slots used" (bottom right).
I guess there is other ways but, there is a program called aida64(formerly everest or something). You can use it. Here is your link https://www.aida64.com/downloads
You can use a very simple software called CPUID - https://www.cpuid.com/softwares/cpu-z.html
Some websites have plugins that allow you to discern this. One such is Crucial. http://uk.crucial.com/gbr/en/memory-info
