DDR3 Memory Module Sockets Amphenol FCI Memory Module Sockets are designed to accept most industry standard memory types (DDR, DDR2, DDR3) and form factors such as DIMM, SO-DIMM, or VLP DIMM. The DDR3 Memory Module Sockets allow convenient memory expansion in servers, workstations, desktop PCs, mobile PCs, and embedded applications in communications and industrial equipment. Amphenol FCI DDR3 memory sockets accept 240-position DDR3 memory modules as per JEDEC MO-269. Low contact resistance versions support the use of RDIMM (registered DIMM) which is becoming more and more popular in use because it helps further reduce power consumption in data communications systems such as servers.
