This article provides information on DDR3L memory currently shipping on newer Dell notebooks and laptops
Newer Notebook systems are utilizing Intel 4th Generation processors that require a new type of memory SoDIMM 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.
fig1: image shows the difference in labelling between DDR3 memory module and DDR3L memory module.
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.
