Today, computers have become the people's work and play an indispensable equipment, more and more people choose a DIY their own PC. Prior to the actual installation, further understanding of the hardware is necessary, Take memory, although now the mainstream is already selected DDR4, many people still do not know the difference between these two DDR3 and DDR4 specifications that bought the hardware is not compatible. Hong Wang and below semiconductor look together DDR3 and DDR4 in the end what difference.
DDR3 memory specification is a computer, it belongs to the family of SDRAM memory products, provides operational performance and lower voltage compared to DDR2 SDRAM is higher, DDR4 memory is the next generation of memory specifications, it is based on the development of the DDR3 up, more dominant than DDR3. Compared to the previous generation DDR3, the new generation DDR4 memory mainly the following core change.
Appearance change
DDR4 memory is obvious change in appearance, reaching 284 contacts, finger into a curved shape, is easy to plug and reduce the pressure of PCB, the slot position different from both modules. This means that, DDR4 memory is no longer compatible with DDR3, DDR4 old platform computer memory can not be upgraded, unless the CPU and motherboard replaced with a new platform.
Memory clock speed
Terms of frequency, starting DDR3 memory frequency of 800, the highest frequency reached 2133, DDR4 memory starting frequency reached 2133, the highest frequency of mass production reached 3,000, the frequency of view from memory, DDR4 DDR3 upgrade compared to great. Bandwidth, each pin DDR4 memory can provide bandwidth 2Gbps (256MB / S) of, DDR4-3200 and that is 51.2GB / s, more than 70% higher than the ratio of DDR3-1866. On the whole, DDR4 DDR3 memory performance than the most significant improvements of up to 70%, or even higher.
Memory capacity increase
Memory capacity, DDR3 memory singled maximum capacity of 64GB, the actual can buy basic is 16GB / 32GB, while the next-generation DDR4 memory, a single maximum capacity up to 128GB, comparable to the SSD.
Lower power consumption
Power consumption, DDR3 memory with standard voltage 1.5V, DDR4, decreased power consumption, the voltage drops below 1.2V or even lower, the decrease in energy consumption, less power, and can reduce heat generation of memory.
DDR4 and DDR3 memory can be generic it?
Obviously, due to the appearance of the slot position is not the same, DDR4 and DDR3 can not be universal. Two kinds of memory uses a different form of the interface, the motherboard can only support one. The motherboard supports DDR3 memory, does not support the use of DDR4 memory, empathy, support for DDR4 memory board can not install DDR3 memory.
ICMAX DDR Model
Overall, DDR4 and DDR3 compared in various aspects have improved significantly, superior power and performance to the more powerful and robust multitasking and run the big game provides a solid hardware foundation, mostly in the field of PC DDR4 memory modules, DDR3 also have their own application market. Hong Wang semiconductor ICMAX DDR due to the superior cost-effective high performance with high competitiveness, with many well-known manufacturers.
1, different specifications
DDR3 memory starting frequency only 800MHz, the highest frequency up to 2133MHz. The initial DDR4 memory frequencies have 2133MHz, the highest frequency up to 3000MHz. DDR4 memory frequencies higher performance in all aspects of DDR3 memory and has significantly improved compared to, each pin DDR4 memory can provide bandwidth 2Gbps, then DDR4-3200 is 51.2GB / s, which is more than DDR3-1866 the bandwidth upgrade by 70%.
2 , different appearance
DDR4 DDR3 version as an upgrade, a number of changes in appearance. DDR4 memory of Goldfinger into a curved shape, which means that DDR4 is no longer compatible DDR3, DDR4 memory if you want to put on, you also need to replace the motherboard platforms support the new DDR4 memory.
3 , the memory capacity of different
DDR3 largest single capacity of up to 64GB, but the market can buy only 16GB and 32GB. The DDR4 largest single capacity of 128GB, more capacity means that DDR4 can provide support to more applications.
4 , different power
Typically, the DDR3 memory operating voltage of 1.5V, more power, memory and easy to heat down, affect performance. The DDR4 memory operating voltage of 1.2V or even lower and more, bringing the decline in power consumption is less power consumption and less heat generation, enhance the stability of memory, the basic cause of the fever will not drop frequency phenomenon.
Overall, DDR4 and DDR3 compared in every respect has significantly improved. Superior power and performance to the more powerful and robust multitasking and run the big game provides a solid hardware foundation, so my friends the best choice for high-frequency low-power DDR4 product when installed, so as to out a DIY Taiwan excellent PC, you say is not it?
