What is DDR3L memory?



This article provides information on DDR3L memory currently shipping on newer Dell notebooks and laptops.


DDR3L Memory Compatibility

Newer Notebook systems are utilizing Intel 4th Generation processors that require a new type of memory SoDIMM known as DDR3-Low Voltage or "DDR3L".

Note: Systems utilizing Intel 4th generation processors are not backward compatible with regular DDR3 memory modules.

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.

DDR3 vs DDR3L

DDR3L:

  • DDR3L is pin-compatible with DDR3.
  • DDR3L is a dual voltage capable memory SoDIMM, which supports operation at both 1.5V and 1.35V.

DDR3:

  • DDR3 is a single voltage capable memory SoDIMM, which supports 1.5V operation only.
  • It is NOT compatible with systems using 4th gen Intel processors, which exclusively support 1.35V operation for memory.

The DDR3L SoDIMM has "PC3L" whereas the DDR3 SoDIMM has "PC3" in the JEDEC compliant text.
