The standout feature of Transcend's DDR2-667 Fully Buffered DIMM is its optimum performance Advanced Memory Buffer, which acts as an intermediary between the DRAM and the system bus, using an efficient serial-based uplink to communicate with the memory controller. The AMB also performs real-time error correction, which is essential for executing mission-critical or compute-intensive tasks, as it can greatly reduce the risk of computational errors, while at the same time increasing overall system stability.
