The difference for DDR3L 1600mhz & 1333mhz
There are two main differences between DDR3L 1600 mhz compatible 1333 mhz and DDR3 1333 mhz:
1. The working voltage is different. DDR3L memory is low-voltage version of the memory, its working voltage is 1.35V, lower power consumption and more energy-saving; and DDR3 memory is ordinary elegant version of the memory, its working voltage is 1.5V
2. The supported working frequencies are different. The DDR3 1600mhz supports an operating frequency of 1600MHz. Compatible with 1333MHz means that the memory can also operate at 1333MHz. The DDR3 1333 supports a maximum operating frequency of 1333MHz, which cannot work at 1600MHz.
