Notebook systems that are using Intel 4th Generation processors require a newer type of DDR3 SoDIMM memory that is known as DDR3-Low Voltage or DDR3L.
If a DDR3 SoDIMM memory module is inserted into the system, the system will not complete Power On Self-Test (POST). You may get no video displayed with flashing diagnostic lights.
The DDR3L SoDIMM has PC3L whereas the DDR3 SoDIMM has PC3 in the JEDEC-compliant text.

This form of memory operates at 1.8 volts as opposed to the more traditional 2.5 volts and is commonly used in portable electronics. As with all DDR memory, the double data rate is achieved by transferring data on both clock edges of the device. which consumes very low power, produces less heat.
