Without opening my ThinkPad is there a way to determine if the 2GB of memory are in 1 slot leaving 1 slot available for additional memory? If you want to know whether the factory shipped rams are either occupying two slots or one slots without opening.

We already have written a tutorial article in which we have shown how to check the RAM Speed using software called Piriform Speccy. And, today in this tutorial will show you how to check ram frequency using cmd (command prompt) in your Windows 10, 8, 7 and XP PC. The CMD method is fast but if you want to know about your installed RAM memory stick in details and easy way, then you can see our article:How to check ram frequency and RAM type in Windows 10, 8.1, 7, Vista and XP.
In Windows, if you just want to check the RAM speed and RAM Type then you can use two methods one is via Windows Task Manager and the other one is the command prompt. We will discuss the command prompt one here.

How to check ram frequency using cmd via WMIC command
- Go to start menu and type CMD
- Run the CMD command prompt on your Windows system administrator.
- Type the command “wmic MEMORYCHIP get BankLabel, Capacity, DeviceLocator, MemoryType, TypeDetail, Speed” or simply copy paste it.
- If you just want to know the total amount of available RAm on your system, type: systeminfo | findstr /C:”Total Physical Memory”
- And to get information about the available amount of RAM out of the Total physical memory then type: systeminfo |find “Available Physical Memory”
Tutorial with screenshot
The steps we are using in this article are the same for Windows 10, Windows 7, Windows 8, and Windows XP.
We can check the RAM frequency, type and total available memory using two commands in the Windows. One is wmic and other is systeminfo both are the basic Windows command and easy to use. We show you how to use both commands in the steps given below.
Step 1: From the start menu, type the CMD and select the Command prompt option.
Step 2: Once the command prompt of Windows opened, Type the following command and press Enter button:
BankLabel: This will assign a physical label to your RAM like 0,1,2,3… depends upon the number of RAMs installed on your PC.

Capacity: This option will show the capacity of each RAM (in bytes) available on the Windows PC of yours.
DeviceLocator: This syntax of command will show in which slot or channel your RAM has been installed.
MemoryType: If you want to know about your DDR RAM type using the CMD (command prompt) in Windows then this Syntax will show. However, the DDR memory types output it provides are in numbers. Here are the MemoryType output value and its corresponding RAM type installed on your system.
- 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
Here, while performing this tutorial, I got value 24 for Memory Type that means my system RAM type is DDR3.
Speed: Here, you will get the speed or so-called frequency of the RAM of your system in MHz; for which you are reading this article.
TypeDetail – It will tell you type of the physical memory installed on your system. The different value output represents different Type; please follow the value and its corresponding Type details output given below:
- 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

Another Windows Command that will show complete details about your installed RAM is
The output of this a bit clutter and confusing but still you use it to get full detail about the RAM of your system.
Command to see the total amount of RAM and Available Physical memory on the Windows
As I told, you can use the sysyteminfo commands on CMD of Windows to know about the total physical memory, here they are:
First will show the total amount of RAM and second gives info about the available RAM to use out of the Total.

1 Before you learn how to check RAM type in Windows 7, you need to know what the technology actually does.RAM is generally the acronym for RANDOM ACCESS MEMORY. Clearly, it indicates that it can store the randomly accessed memory or information that are necessary for running various programs on the system.
But it is important to know that RAM can store any piece of information as long as the system is on. When the system is turned off, it will lose all the randomly stored data.
Now the common question is why you need to know the type of your RAM. Well, on a precise scale, it will tell you about the processing speed of your PC and you can apprehend what better option you can opt for RAM to increase the speed furthermore.
Here in this article, we would provide two basic tricks to help you know your PC’s RAM type in Windows 7.
Trick #1: Use CMD to Know RAM type in Windows 7
CMD, commonly abbreviated for command prompt, we all know helps to coordinate any task with the help of certain commands.
Though it is risky to use if you are not adept with command lines, yet very powerful if you know how to.
The steps for the trick to follow are:
Step 1. Press “Windows logo + R” and “Run” search panel will open up at the bottom left corner of the home screen.
Step 2. Enter “cmd” and click “Ok”.
Step 3. As soon as the black dialogue box pops up, enter the command recommended below:
“wmic MEMORYCHIP get BankLabel, Capacity, DeviceLocator, MemoryType, TypeDetail, Speed”
Now the output of the command will brief you about the number of installed RAMs, their capacity, speed, type, etc.
But here in this section we only want to know the RAM type.
For this look under the output column “MemoryType” and you will find few numbers. Each number represents a particular type of RAM. The list of numbers and the corresponding RAM they represent are given below:
- 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
Trick #2: Use Third-Party Tool to Know RAM Type
This is a very direct and smooth approach towards knowing the RAM type. Here we would make use of a free third party utility to know the RAM type.
The steps for the method are detailed below:
Step 1. Firstly, go to CPUID and download the freeware CPU-Z software on your PC:
Step 2. Install the program and launch it with admin privileges if possible.
Step 3. The software will do a quick scan of your PC and will display all the details of your PC. The detailed are organized into convenient tabs.
Step 4. Next, go to the “Memory” tab, and all the information of RAM, that is RAM type, frequency, size, NB frequency, etc. will be displayed.
Conclusion:
Both the above methods are easy to work out on how to check RAM type in Windows 7, but if you have poor internet connectivity, the first method using cmd will be more appropriate.

On a manual scale, you can also check the RAM type by opening the CPU cabinet and excavating out the RAM from its slot to check its type in case none of the trick works. But surely it would be hectic so mostly avoided by users.
