location (figure ).　　　　The memory used by the motherboard is determined by the chipset, because the beiqiao chip contains an extremely important memory controller. It should be noted that some boards using the via and SIS chipset may support both SDRAM and DDR at the same time, but the SDRAM and DDR memory cannot be mixed.　　　　3. Power Supply and motherboard combination:　　So far, The ATX Power interface has completely replaced the traditional at Power

RDRAM use the 184pin interface. In fact, it is unrealistic to distinguish between 168pin and 184pin by the number of pins, but we can identify the gaps in the memory slot by identifying the gaps, and it is foolproof. The memory slots with 168pin have two asymmetric gaps between the center and the right. The memory slots with 184pin have only one gap.The RDRAM memory slot of the 184pin has two gaps on the symmetric position (figure ). The memory used by the motherboard is determined by the chip

From http://blog.mcuol.com/User/luozhen0810/Article/9700_1.htm Printed circuit boards (PCB) appear in almost every electronic device. If there are electronic parts in a device, they are all mounted on PCB of different sizes. In addition to fixing all kinds of small parts, the main function of PCB is to provide the electrical connection between the above parts. As electronic devices become more complex and more parts are required, the line and parts o

Opening one: Server boardServer Board Overview For the server, the stability is the first, the server must bear the high and low workload of the work requirements, and can not be as random as the desktop to restart, in order to improve the reliability of the general approach is the redundancy of the parts of the technology, and all this support falls on the motherboard shoulder. Let me take a look at some of the features of the server board: 1, first of all, the scalability of the server determi

purchased from Ettus. Ettus is probably the oldest SDR hardware producer. They have produced a lot of different usrp. The USRP b200/210 is completely different from the previous old product, which is a "veneer" design and is no longer a combination of "motherboard/sub-board". It also uses the USB3 interface, which supports a wide range of RF bands. The b200/210 has a newly designed GPSDO connector that can be adjusted to several PPB via the GPS module. B210 is also the Ettus's first standalone

Bucket LawThe short board theory is developed by American management experts.PeterProposed. Its core content is: the amount of water in a bucket does not depend on the highest block on the bucket wall, but on the shortest block on the bucket wall. According to this core content, there are two inferences about the bucket Theory: first, the bucket can be filled with water only when all the boards on the bucket wall are high enough. Second, as long as th

capacity of the bucket depends on the height of the shortest board. However, in a specific State of use, through mutual cooperation, you can increase a certain amount of water storage, such as consciously tilting the barrel to the direction of the long board, its water storage volume is much larger than the bucket when it was set up. Or to temporarily increase the water storage volume, you can cut down the long board and add it to the Short Board to increase the water storage volume. The long
