A set of high-end Core i5 750 processor with DX11 special effects HD5770 graphics platform generally needs at least 6000-7000 yuan price. Today, some dealers have offered a price of less than 6,000 yuan for this platform. Regarding the accessories of this computer configuration, the MSI P55-CD53 motherboard is one of the most popular P55 products in the first line. The overall workmanship of the main board is solid, and there is no design that is not used by mass consumers, so the price has also shrunk dramatically. However, some regrets that although it is a P55 motherboard, it does not support dual-card crossfire capability. Be aware that this is the technology that the P55 motherboard natively provided, not from vendor cracking.
Let's take a look at this civilian-class Core i5 750 configuration that has been turned into a mass consumer.

Computer configuration comment: This set of assembled computer configuration performance is good, and there is not much difference with the full price for the product, but this is based on the premise of loss of peripheral products and other product performance. Low-end display, low-end power supply, chassis, low-end mouse and keyboard. Presumably, these peripheral products have seriously affected the overall performance. In particular, the performance of the display seriously affects the 3D picture quality. Of course, if you build on such a low price, you can only endure it.
The problem
Throughput is an important indicator of Ethernet testing. Many engineers believe that the Ethernet switching throughput should be its line rate, that is, no packet loss can occur at 100% traffic, and that it is illegal for the Ethernet frame interval IFG to be less than 96 bits. However, in the Ethernet switching throughput and packet loss rate test, a small amount of packet loss occurs in the long-term error test under the line speed condition. The reason is the cross-clock domain architecture of the Ethernet.
With the rapid development and application of industrial Ethernet technology, a large number of network problems have appeared along with it. According to statistics provided by Siemens, the network communication failure rate accounts for more than 70%, and the network equipment failure rate is less than 30%. After a network failure causes the system to shut down, the time required for fault diagnosis and location accounts for more than 80% of the total system downtime, while maintenance measures take up less than 20%. Therefore, real-time monitoring and analysis of network traffic is a major problem in the development and application of industrial Ethernet. Real-time monitoring and analysis of industrial Ethernet network traffic and timely detection and location of network problems play a vital role in improving the stable operation of the entire system. .
