into the CPU. The functionality of the chipset in Figure 3 is similar to the South Bridge, functionally like an I/O hub (I/O hub) or called "IOH" in Intel's jargon.Each channel (lane) can transmit 20 bits at a time, where 16 bits are actual data and 4 bits are redundant error correcting codes (CRC). The first version of the QPI has a working frequency of 3.2GHz and is capable of transmitting two data in one clock cycle (that is, DDR technology), whic

The first version of the QPI has a working frequency of 3.2GHz and is capable of transmitting two data in one clock cycle (that is, DDR technology), which makes the bus operating frequency appear to be at 6.4GHz (Intel uses

Intel's QuickPath Interconnect technology is abbreviated as QPI, which translates to fast channel interconnection. In fact its official name is called the Csi,common System interface public interface, used to achieve direct interconnection between chips, rather than connecting to the North Bridge via FSB, directed at AMD's HT bus. Regardless of speed, bandwidth, the bandwidth of each stitch, power consumpti

My company's new website highlights encyclopedia was launched and encountered this problem when using FTP. The main manifestation is: the transmission speed starts to be fast, and then gradually decreases in a few seconds, and finally changes to 0. After a while, the system prompts a new connection and overwrites the upload, but the speed remains the same You have to disconnect and start again !! This probl

Although the Win7 system installed faster than other systems, but as the use of time, will lead to slow down the speed of the system, and just installed the system when the operating speed gap is very large, so how to speed up the speed of the Win7 system? In fact, there are many ways, The following Win7 's small serie

In the contest, when the large data is encountered, the reading file becomes the bottleneck of the running speed of the program, and it needs a faster reading mode. It is believed that almost all C + + learners have stumbled over the slow speed of the CIN machine, and have vowed not to read the data on the CIN. Others say that the speed of Pascal's read statement
