1. Unplug your computer memory from the computer motherboard, and then check the working frequency of the memory yourself. If you find it inconvenient to remove the memory of the computer, you can use the second method at this time.
2. Use software to test the memory model, such as installing CPU-Z on the computer. You can download and install CPU-Z from Baidu, then install it on your own computer, and finally run the installed program.
3. after opening CPU-Z, click on the memory here to see the memory model and display the DDR3 generation memory.
4. Then, in order to see more accurate information, we click SPD to open it, click the slot here on the left, and then check the information such as memory model and bandwidth frequency. Click the slot here on the left to see how many slots have memory sticks.
Extended information:
There are two types of memory, namely DRAM and ROM. The former is also called dynamic random access memory, and its main feature is that data will be lost after power failure, which is what we usually mean by memory; The latter is also called read-only memory. We usually start the BIOS program stored in ROM on the motherboard at first, and then use it to call Windows on the hard disk. One of the main features of ROM is that data will not be lost after power failure.
according to the number of pins on the memory stick, we can divide the memory stick into 3 lines, 72 lines and 168 lines. The 3-line and 72-line memory banks are also called single-line memory modules SIMM (SIMM is a memory structure in which both gold fingers provide the same signal), and the 168-line memory banks are also called dual-line memory modules DIMM.
the p>3-line memory stick is gone; The popular variety in the first two years is 72-line memory chips, and their capacities are generally 4 megabytes, 8 megabytes, 16 megabytes and 32 megabytes. The mainstream variety in the market is 168-line memory chips, and the capacity of 168-line memory chips is generally 16 megabytes, 32 megabytes, 64 megabytes, 128 megabytes, etc. Generally, it is OK to plug one into a computer, but only motherboards based on VX, TX and BX chipsets can support 168-line memory chips.
