Modern memory microcircuits for use in personal computers are placed in sets of several pieces on textolite strips with a length of slightly more than 133 millimeters. The number of microcircuits determines the total capacity of each such bar, and in addition to this parameter, the type of microcircuits used is also important - the speed at which information can be read or written to the RAM depends on it. The type of memory can be found from the information stickers printed on the strips, but the user does not always have access to the computer hardware. You can also get the necessary information programmatically.
Instructions
Step 1
The best suited for determining the type of installed memory chips are specialized programs designed to collect and organize data on computer hardware. The most common applications of this type are CPU-Z (https://cpuid.com/softwares/cpu-z.html) and AIDA64 (https://aida64.com/downloads). The first of the programs is completely free, and the second has wider possibilities and is not limited only to passive collection of information. Choose the application that suits you the most, download it, install and run it.
Step 2
If you decide to use CPU-Z, then go to the Memory tab of the application interface. You will find the memory type in the upper section (General), in the Type field, and in the line below (in the Size field) you can find out the total amount of all memory chips installed in the computer. In total, this tab contains more than a dozen fields that display in real time information related to memory chips
Step 3
If the AIDA64 program is installed, find the "Computer" section in the left column and click the "Summary information" subsection. In the right column, in the "System memory" field, you will see the available amount of RAM and its type. The next few lines provide more detailed information separately for each memory slot of the motherboard - not only the type, timings and speed are indicated here, but also the chip manufacturer
Step 4
If you cannot use application programs, you can try to determine the type of memory using the built-in components of Windows. Press the Win + R key combination, type powershell in the program launch dialog and click the OK button. This will open a command line interface where you enter gwmi Win32_PhysicalMemory | ft DeviceLocator, MemoryType -a. As a result of its execution, a small table will be displayed, the number of lines in which will correspond to the number of memory slots used by the computer. The MemoryType column of each line will contain the memory type code - number 22 corresponds to DDR-3, number 21 corresponds to DDR-2, and number 20 corresponds to DDR.
