How to see DDR memory type in command prompt in Windows 10

 1. Open an elevated command prompt.

 2. Type the following command

wmic MemoryChip get BankLabel, Capacity, MemoryType, TypeDetail, Speed, Tag
The command produces the following output:





In our case, the information we need is MemoryType. Its value has the following meaning:

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—May not be available; see note above.
25 = FBD2

So in my case, it is DDR3, which is MemoryType of value 24.
Other memory details are as follows:

  • BankLabel - physically labeled bank where the memory is located.
  • Capacity - total capacity of the physical memory—in bytes.
  • Speed - Speed of the physical memory—in MHz.
  • Tag - Unique socket identifier for the physical memory.
  • TypeDetail - Type of physical memory represented. It can be as follows:
    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
    

If Task Manager gives you wrong information or no information at all on the type of memory you have, you can query memory details using the command prompt and see what exactly Windows knows about your memory chips.

That's it.
