b) Go to Start Menu, Accessories or Windows System(Windows 10), and click on Command Prompt.

In Command Prompt,

Use part or all of this command as desired:

wmic memorychip get banklabel,capacity,devicelocator,memorytype,speed,tag,typedetail

From the above wmic query result of my PC,

I have 2GB + 1GB + 1GB + 1GB = Total 5GB installed in A0, A1, A2, A3 Slots of MemoryType DDR2, Speed 667MHz Physical memory (Hardware RAM).

BankLabel - Physically labeled bank where RAM is located.
Capacity - Total capacity of the physical memory in bytes.
DeviceLocator - Physical labelled slot numbers.
Speed - Speed of the RAM in MHz.
Tag - Unique socket identifier for the physical memory.
MemoryType - Type of memory. For eg DDR3
TypeDetail - Type of physical memory.

MemoryType identification values:

0 = Unknown
1 = Other
2 = DRAM
3 = Synchronous DRAM
4 = Cache DRAM
5 = EDO
6 = EDRAM
7 = VRAM
8 = SRAM
9 = RAM
10 = ROM
11 = Flash
12 = EEPROM
13 = FEPROM
14 = EPROM
15 = CDRAM
16 = 3DRAM
17 = SDRAM
18 = SGRAM
19 = RDRAM
20 = DDR
21 = DDR2
22 = DDR2 FB-DIMM
24 = DDR3
25 = FBD2

DDR4 may show 0 = Unknown

TypeDetail values:

1 = Reserved
2 = Other
4 = Unknown
8 = Fast-paged
16 = Static column
32 = Pseudo-static
64 = RAMBUS
128 = Synchronous
256 = CMOS
512 = EDO
1024 = Window DRAM
2048 = Cache DRAM
4096 = Non-volatile

Now that you know, type the command and find out all about your RAM without the need of a scan tool.
