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 .

Systems with CAMM memory already installed cannot be expanded through adding additional CAMM modules in the same way that 2 DIMMs can be added alongside 2 existing DIMMs to expand total system memory. Instead, the entire CAMM module must be replaced with one with a higher capacity. So CAMM may be of benefit for laptops and ITX systems.
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.
