PCI Express* 3.0 438-Pin Riser Card Edge Connector Spec
This document provides specifications for the PCI Express* 3.0 438-pin riser card edge connector that interfaces with a riser card supporting up to 48 PCIe lanes at 8 Gbps and power at 12 V, 5 V, and 3.3 V. It contains mechanical, electrical, and environmental requirements of the connector accepting 2.36 mm (0.093 in.) nominal ...thickness add-in card. The intent of this document is to enable connector, system designers, and manufacturers to build, qualify, and use the PCIe riser card edge connectors as the standard interface between the PCIe riser card and the Intel® server Platform.
