DDR3 vs DDR3L
Summary: The difference between DDR3 and DDR3L is the consumption of the voltages. DDR3L is the newer version and consumes less voltage as compared to DDR3 which ultimately makes the operations faster and reduce heating.
DDR3 stands for Double Data Rate Type 3 which is a type of DRAM (Dynamic Random Access Memory) which came after the DDR and DDR2 in the market as a new version of DRAM. The first DDR3 was introduced in the market in 2007 now most desktop or laptop computers are using DDR3 as RAM. DDR3 use 1.5 Voltage and consumes very less power as compared to the older versions of DRAM, DDR and DDR2. DDR3 allow chips capacity up to 8 GB. In market DDR3 is available for different types of frequencies such as 1066, 800, 1600, 1333, 2133, 1866 MHz. A DDR RAM which has 240 pins and length 133.35 mm is used for personal computers. But the DDR3 Modules used in laptops are much smaller having length of 67.6 mm and 204 number of pins and are known as SO-DIMM.
A special type of DDR3 was then introduced known as DDR3L where the letter “L” in the name refers to the low voltage standard. It uses only 1.35V which is 0.15V lower than the ordinary DDR3. So, the plus point using DDR3L is that the power consumption is low. And when there is less power consumption, your battery life will be enhanced. DDR3L is mostly used in mobile devices, embedded computers and laptop computers rather than in Personal Computers. The benefits from low power consumption your computer will get is less heat generation, useful for mobile devices. Other specifications of this DRAM such as frequencies, memory density and other protocols are same as DDR3. And the DDR3/DDR3L Modules used in laptops are much smaller having length of 67.6 mm and 204 number of pins and are known as SO-DIMM. DDR3L have SO-DIMM Slots and is targeted for mobile devices.
