What is FBD memory

FBD is Fully-buffer DIMM (full cache module technology), which is a serial transmission technology that can improve memory capacity and transmission bandwidth. It is a new type developed by Intel based on DDR2 and DDR3. The memory module and interconnect architecture can be used with current DDR2 memory chips or with future DDR3 memory chips. FB-DIMMs can greatly increase system memory bandwidth and greatly increase the maximum memory capacity.

FB-DIMM memory technology is Intel's performance in order to solve the constraints on the overall system performance and developed to achieve a leap in performance improvement based on existing technology, but the cost is relatively low. In the entire computer system, memory can be said to be a key factor in determining the performance of the whole machine. There is a fast CPU, no good memory system to match it, and the CPU performance is excellent and can not be played. This situation is determined by the computer principle. The data required by the CPU during the operation is obtained from the memory. If the memory system cannot supply data to the CPU in time, the CPU has to wait for a long time in a waiting state, hardware resources. Idle, performance is naturally not available.

Compared with the existing ordinary DDR2 memory, FB-DIMM technology has great advantages: it can provide four times the bandwidth of ordinary memory and the maximum memory that can be supported at the same memory frequency. The capacity is also 24 times that of ordinary memory, and the system can support up to 192GB of memory. The biggest feature of FB-DIMM is the use of existing DDR2 memory chips (later DDR3 memory chips will be used), but it converts parallel data into strings by means of a buffer chip AMB (Advanced Memory Buffer) on the memory PCB. The data stream is streamed and transmitted to the processor via a point-to-point high speed serial bus like PCI Express.
