DDR4 RAM operates at a voltage of 1.2 V and supports frequencies between 800 and 1600 MHz (DDR4-1600 through DDR4-3200). Compared to DDR3, which operates at 1.5 V with frequencies from 400 to 1067 MHz (DDR3-800 through DDR3-2133), DDR4 offers better performance and energy efficiency. DDR4 speeds are advertised as double the base clock rate due ...
Low-Power Double Data Rate (LPDDR), also known as LPDDR SDRAM, is a type of synchronous dynamic random-access memory (SDRAM) that consumes less power than other random access memory designs and is thus targeted for mobile computing devices such as laptop computers and smartphones.
Compared to DDR2 memory, DDR3 memory uses less power. Some manufacturers further propose using "dual-gate" transistors to reduce leakage of current. [10]According to JEDEC, [11]: 111 1.575 volts should be considered the absolute maximum when memory stability is the foremost consideration, such as in servers or other mission-critical devices.

The SDRAM module has two notches (rectangular cuts or incisions) on the bottom edge, while the DDR1 SDRAM module has one. Also, each module has eight RAM chips, but the lower one has an unoccupied space for the ninth chip; this space is occupied in ECC DIMMs. Three SDRAM DIMM slots on a ABIT BP6 computer motherboard.
The Surface Pro 4 is an update over its predecessor, featuring Skylake CPUs, more RAM and SSD options, and a 12.3-inch display with a greater resolution. At the same time, the device is compatible with most of its predecessor's accessories.
