Regarding voltage selection: It is recommended to give priority to low voltage, low voltage compatible standard voltage, most standard voltage is not compatible with low voltage!
Sky blue, blue does not represent the color of the memory, it is just used to mark the voltage! No practical significance!
Low pressure = recent years (about 13-15 years)Corresponding CPUI3 I5 I7 three-generation four-generation five-generation version
Low voltage notebook computer, DDR3L=PC3L=low voltage 1.35V
Standard pressure = about 12-13 years of correspondenceCPUI3 I5 I7 second generation, third generation, please choose standard voltage more suitable!
DDR3=PC3=standard voltage 1.5V!
