1. Download software CPU-Z
   

2. How to see the parameters of
   CPU-Z CPU-Z detection CPU model comprehensive analysis

3. Check the voltage of the memory , click the SPD tab,
   voltage is 1.50V-DDR3 generation standard voltage memory
   voltage is 1.35V-DDR3 generation low voltage memory
   voltage is 1.20V-DDR4 generation memory
   

4. To view the memory frequency,
   you can directly use the command line window, cmd and then wmic memorychip

   The memory frequency is multiplied by 2, that is, 800*2 is approximately equal to 1600, which is the actual operating frequency of the memory.
