extension of the basic definition of the original meaning and symbolic significance of the role of Northbridge Northbridge Northbridge Northbridge chip features AMD platform, another name for intel platform leading blue-chip North Bridge Causes and solutions of problems the phenomenon of death crash summarizes the basic definition of a bridge north of the original meaning of the standard of the ancient city has four doors, for the east, west, south and north doors. Normally have moat, if you are sitting in the city's north bridge, the general called So now there are many cities in China, Example: Pingxiang City of Jiangxi Anyuan Ping River area have so far on the Ping River as well as And symbolic significance of an extension of computer motherboards, according to a certain method of holding to the north side of CPU socket, then close to the CPU socket to do with a connection from the chip known as the English name: North Bridge Chipset. North Bridge Chip North Bridge chip (NorthBridge) is the motherboard chipset plays a dominant role in the most important part, but also
Intel G45 Northbridge chipset
as the main bridge (HostBridge). Generally speaking, the name of the chipset North Bridge chip is to name names, such as the Intel GM45 chipset North Bridge chip is the G45, the latest is to support Core i7 processor X58 series north bridge. There mainstream P45, P43, X48, 790GX, 790FX, 780G, 880G, 890GX, 890FX and so on. NVIDIA also 780i, 790 / etc. The role of the Northbridge chipset and the CPU North Bridge chip is responsible for contact and control memory (only Intel i7 series than outside cpu, AMD K8 series after series of cpu on the cpu in the integrated memory controller, AMD platform, does not control the Northbridge chip memory ), AGP data transfer within the North Bridge to provide the type and frequency of the CPU, the system's front side bus frequency, memory type (SDRAM, DDR SDRAM and RDRAM, etc.) and the maximum capacity, AGP slot, ECC error correction and other support , integrated chipset North Bridge chip also integrates a graphics core. Features Northbridge Northbridge chip on the motherboard is the latest chip from the CPU, which is mainly taking into account the Northbridge chipset and processor communication between the most closely, in order to improve communication performance and reduce the transmission distance. Because the North Bridge chip data processing is very large, the heat is also growing, so now the North Bridge chip is covered with a heat sink used to strengthen the North Bridge chip cooling, and some will be with the motherboard Northbridge chipset fan for cooling. Because the North Bridge chip, the main function is to control the memory, and memory as standard and the processor change more frequently, so that different chipset North Bridge chip is certainly different, of course, does not mean that the memory technology used is completely different, but different between the chipset North Bridge chip definitely a difference in some places. Northbridge Northbridge another name distinct role to play in the computer plays a leading role, so people used to called the main bridge (Host Bridge). intel platform Intel845 series chipsets 82845E/82845GL/82845G/82845GV/82845GE/82845PE, other than 82845GL support 533MHzFSB (82845GL only support 400MHzFSB), support memory, the more than 845 series northbridge chips support up to 2GB of memory, 82845G/82845GL / 82845E support DDR266, the rest are supporting DDR 333, another 82845G/82845GL/82845GV also supports PC 133SDRAM, except 82845GL/82845GV outside support AGP4X slots; 865-series chipsets 82865P/82865G/82865PE/82865GV/82848P, except 82865P outside support 800MHzFSB, DDR 400 (82865P only supports 533MHz FSB, DDR333, except 82848P outside support dual channel memory, and 4GB maximum memory capacity (82848P only supports single-channel maximum 2GB memory), in addition to outside support AGP8X 82865GV slots; Intel Desktop AGP platform is the most high-end 875 series 82875P Northbridge, support 800MHz FSB, 4GB dual-channel DDR400 and PAT functions.

ATI: ATI AMD platform chipsets into the market relatively late, early K8 series CPU that supports the Radeon Xpress 200 (North Bridge chip is the RS480) and RadeonXpress 200P (North Bridge chip is the RX480), which both support the PCI Express X16 standard, which, Radeon Xpress200 support for DirectX 9.0 also integrates the Radeon X300 graphics chip. Radeon Xpress200 have compared the two technologies unique, one memory, shared memory and the system can also can use on-board memory and system memory; the second is Radeon Xpress200 CrossFire (RD480), Xpress CrossFire 3200 (RD580) and Xpress CrossFire1600, support the HyperTransport 1000MHz frequency and PCI Expressx16 graphics slot and support CrossFire multi-graphics parallel technology. which, Xpress CrossFire3200 (RD580) is in the Northbridge chip with 40 PCI Express Lanes, can support two full-speed PCI Expressx16 graphics slot, you can maximize the power of CrossFire technology. The latest is the Radeon Xpress 1100 and RadeonXpress 1150 two kinds of Socket AM2 platform chipset to support all Series SocketAM2 processors support the HyperTransport 1000MHz frequency and PCI Express x16 graphics slot, and both integrated graphics core ATI RadeonX300, but the core of the two different frequencies, Radeon Xpress 1100 core frequency is 300MHz, while the Radeon Xpress1150 the Core frequency is 400MHz. northbridge chip lead to blue screen crashes cause analysis and solution of a phenomenon of computer use, frequent crashes of the phenomenon. At first I thought was infected by any viruses found after the killing. and that is the hard disk fragmentation too much, resulting in system instability. But even after defragment the hard disk does not solve problems. reformat the system disk, reinstall the system, but the problem is still not resolved, seriously affected the daily work. reinstall the system after the crash of fault is not excluded, seems to be hardware problems. just beginning to question the memory failure. But after the replacement of memory failure is still not resolved. that question in the end there where is it? through careful analysis, since the memory is no problem, most likely the motherboard failure. So Using substitution, the replacement of the motherboard, open the computer, fault disappears, the root of the problem seems to appear in this board. motherboard work with the materials quite general. carefully examined and found capacitors on the motherboard does not breakdown phenomenon, the PCB board, have left no traces of burnt, then in the end, which part of the motherboard problems. So clean up again after re-board computer access into a variety of equipment. boot crash occurred half Shiyou phenomenon, then hand-to-board heat sink on the Northbridge chip, and found a very hot, it seems that the problem is there something like that. to purchase a piece of the radiator with a fan, after some agonizing, finally been replaced, and replacement down the North Bridge heat sink installed in the South Bridge chip. begins after some testing, fault completely ruled out, then through careful analysis, they would understand the reasons for this failure. the original machine is equipped in the winter, the temperature is lower did not have much effect, and then after the summer exposed the problem. The question summed up such problems, in general, consider the memory will go. However, due to CPU Cache problems caused by bad or the motherboard designs are also prone to heat frequent crashes of the phenomenon. The author had a certain brand 845PE motherboard that is not good enough for the motherboard heat caused the failure. surrounding the crash, after touching the motherboard components CPU, found that the temperature is very high and hot. Replace the fan power after the crash fault be resolved. Cache problem for the failure, you can enter the CMOS setup program, the Cache can fix the problem after the ban, of course, Cache after the ban will certainly affect the speed of it.
