As an important tool for the information age, computers have been upgraded and updated with the increasing use of users and the continuous upgrading of software. As one of the important accessories, the improvement of technology and the demand of the times drove its replacement. From the iconic DDR era to the DDR2 era, to the longer DDR3 era, DDR4 was finally ushered in. Currently DDR3 and DDR4 are common. Become the mainstream choice in the memory market.

Taking the Swift Sirius series DDR3 and DDR4 as an example, what is the difference between DDR3 and DDR4?

First of all, in terms of appearance, DDR3 and DDR4 are very different in the design of the golden finger. The gold finger of DDR3 is designed in parallel along the line, the gold finger of DDR4 is convex in the middle, and the curve of the two sides is designed to be better inserted and removed. , has the effect of extending the life of the memory. The DDR4 memory gold finger is in full contact with the memory slot contacts to ensure stable information transmission. There are 288 DDR4 gold finger contacts and 240 DDR3s. Compared to DDR3, DDR4 has more bandwidth, and the 'gap' is closer to the middle, and the probability of users inserting wrong memory is lower. So how to identify the difference between the DDR3 and DDR4 of the Swiss Tiave series, in addition to the different vest appearance, can also be distinguished by the different shapes of the gold finger.

For performance, the first is the change in capacity. The same unit of DDR4 chip has more storage space than DDR3, and DDR4 can carry up to 8 modules, which is twice as large as DDR3, which means that the maximum capacity is more than DDR3. 4 times, such as: DDR3 capacity can be 8GB, and DDR4 capacity can reach 32GB. The Sirius series DDR3 memory capacity is 4GB-8GB, and the Sirius series DDR4 memory capacity 4GB-16GB is more widely available. In addition, the voltage changes, the voltage of DDR4 is 1.2V, and the DDR3 is 1.5V, which is reduced by 20%, which is more energy-efficient.

The focus is on the replacement of the processor. The frequency of DDR4 is significantly improved compared to DDR3. The starting frequency of DDR3 is 1333MB/s, the highest frequency is 2133MB/s, and the starting frequency of DDR4 is already 2133MB/s. The frequency can be increased to more than 3200MB/s. Currently, DDR4 high-frequency memory is mostly maintained at around 3000MB/s. The frequency of the Swift Sirius series DDR4 is maintained at 2400MB/s, while the upcoming Rising overclocking memory wolf series and the Wolverine series have reached 3200MB/s. The increase in frequency has led to a small drawback of DDR4 over DDR3. In the case of the same frequency, DDR3 has a lower latency, which has a certain impact on large games. DDR4 needs to be strengthened in this respect.

The replacement of memory has important significance and impact on the memory industry, but currently DDR4 has not yet surpassed every aspect of DDR3. For example, latency is an important issue, and the recent price hike of DDR4 has caused the market demand for DDR3 to re-emerge. Improvement, it can be seen that it is still in a period of collision. It takes a long time and a perfect opportunity for DDR4 to completely replace DDR3.

In order to adapt to the replacement of DDR3 and DDR4, motherboard manufacturers have also adapted to the motherboard platform. At present, Intel H61 chipset, some D3 versions of Intel H110 chipset, AMD A68 chipset and other motherboard platforms support DDR3; Intel Z370/Z270 The mainstream motherboard platforms such as the /B250/H110 chipset and the AMD X370/B350 chipset are suitable for DDR4. Whether the motherboard is selected correctly has a decisive influence on whether the memory can be read correctly and the normal running memory. It is necessary to recognize the type of memory supported by the motherboard when selecting.
