1.00mm (.039") Pitch Fully Buffered DIMM Socket 240 Circuit With Color Options FEATURES AND SPECIFICATIONS Molex offers the Fully Buffered DIMM with color options for server applications. The development of Fully Buffered DIMM (FB DIMM) came from the need for larger and faster memory capacity where memory coordination and accuracy at high speeds are critical which DDR2 is not capable of supporting. 48206 Vertical, Through Hole The FB DIMM is a variant of the DDR2. It combines the high-speed internal architecture of DDR2 with a bi-directional point-to-point serial memory interface which links each FB DIMM module together in a chain. The difference is here in which the DDR2 uses a single memory bus. Molex is an active member of the JEDEC work group that defines industry standards for memory. This allows Molex to ensure that all our memory sockets are 100% industry compatible.
