Memory, as one of the important core hardware in computers, serves as a bridge to communicate with other computer hardware and CPUs. Therefore, the performance of memory has an obvious impact on the computer. For game players, memory is also an important factor in the gaming experience.
As computer memory enters the DDR4 era, it is also developing towards high frequency and low power consumption. What are the differences compared to the previous version (DDR3), and what are the areas that users should pay attention to when updating and purchasing memory?
In order to make better contact between the memory finger and the memory slot on the motherboard, the fourth generation of desktop computers has optimized the gold finger design, changing from the original horizontal straight type to a curved type, adopting a design with a slightly longer middle and a slightly shorter two ends; Because the frequency of laptop memory insertion and removal is not high, no such changes have been made in the design of the gold finger.

Capacity difference
In terms of capacity, the maximum single line capacity of DDR3 memory is 16GB, and the mainstream capacity is 8GB. With the increasing demand for memory capacity in systems and applications, the maximum single line capacity of DDR4 memory is 32GB, and the mainstream capacity is 8GB and 16GB (only for standard PC computers). For example, UDIMM desktop computer memory and SODIMM laptop memory are available in four options: 4GB, 8GB, 16GB, and 32GB.

Frequency difference
Frequency, as one of the important parameters of memory products, has always been an important reference factor for users to purchase memory. DDR3 memory has a starting frequency of 800MHz and a maximum frequency of 1866MHz (non overclocking), and a maximum frequency of 2133MHz in overclocking. DDR4 memory has a starting frequency of 2133MHz and a maximum frequency of 3200MHz (non overclocking), and a maximum frequency of 4000MHz+in overclocking. For example, UDIMM desktop computer memory and SODIMM laptop memory have two frequencies: 2666 and 3200, DDR4 memory with higher frequencies performs better than DDR3 in terms of performance.

Voltage difference
With the maturity of technology, the DDR4 memory voltage has reached 1.2V. Compared to the DDR3 memory 1.5V standard voltage and DDR3L 1.35V standard voltage, the power consumption is lower, resulting in a decrease in power consumption and heat generation. This ensures stable operation of the memory module during use and reduces the occurrence of heat generation during operation, leading to frequency reduction.

In summary, DDR4 memory has significantly improved performance and power consumption compared to DDR3 memory. However, DDR4 memory and DDR3 memory are not interchangeable. If users using DDR3 memory modules want to switch to DDR4 memory, the motherboard must be replaced with a new platform that supports DDR4 memory. The memory of SODIMM laptops and UDIMM desktop computers are both DDR4 memory, compatible with mainstream Intel and AMD platforms, and easy to install and replace. After sales, they also enjoy a lifetime limited warranty.
