FBD is the Fully-buffer DIMM (full cache module technology), which is a serial transmission technology that can increase memory capacity and transmit bandwidth. is a new memory module and interconnect architecture developed by Intel on the basis of DDR2 and DDR3, It can match the current DDR2 memory chip, and it can match the future DDR3 memory chip. Fb-dimm can greatly increase the system memory bandwidth and greatly enhance the maximum memory capacity.
FB-DIMM technology is intel to solve the memory performance constraints on the overall performance of the system developed, on the basis of existing technology to achieve a leapfrog performance improvement, while the cost is relatively low. In the whole computer system, memory is the key factor to determine the performance of the machine, the light has a fast CPU, no good memory system with it, CPU performance is no good can not play. This situation is determined by the principle of the computer, the CPU in the operation of the data required are obtained from the memory, if the memory system can not provide data to the CPU in a timely manner, the CPU has long been in a waiting state, the hardware resources are idle, the performance of nature can not play.
Compared with the existing common DDR2 memory, FB-DIMM technology has a great advantage: in the same memory frequency of the current can provide four times times the bandwidth of ordinary memory, and can support the maximum memory capacity is also up to 24 times times the normal memory, the system can support the largest 192GB memory. The biggest feature of FB-DIMM is the use of existing DDR2 memory chip (DDR3 memory chip will be used later), but it uses a buffer chip on the memory PCB Amb (Advanced Memory buffer, advanced memory buffer) to convert parallel data into serial data streams, The data is transmitted to the processor via a point-to-point high speed serial bus similar to PCI Express.
