V100 SXM2 pinout and NVLink reference

By · Published by Everything Blog

In short

The documentation details 800 canonical contacts across twin connectors, supplying developers with signal designations and electrical notes. Editable project files are supplied for KiCad to support layouts ranging from single modules to four-GPU clusters. However, implementations require external differential clocks, including a 156.25 MHz clock for NVLink and a 100 MHz clock for PCIe.

This project aims to become an open-source carrier-board design for NVIDIA V100 SXM2 modules, including NVLink connections for two- and four-GPU configurations.

While that board is being developed, this reference kit shares the pin mappings, connection plans and connector-only KiCad resources so other people can develop their own designs.

My contribution so far is primarily curation: gathering public information, comparing sources, reconciling connector orientation and signal names, and making the results easier to follow. The original reverse-engineering work belongs to its authors, credited in Sources and attribution.

- Download the complete reference ZIP from v0.1.0-reference, or use Code > Download ZIP for the current development files.

- Extract the archive and keep the directory structure. Choose a single-, two- or four-module KiCad starter, then open its

.kicad_pro

file in KiCad 10.0.7 or a compatible newer version. Keep the wholekicad/

folder so the shared symbol library is available. - For reading without KiCad, use the complete schematic PDFs or standalone workbook.

The download guide includes print editions and library-path help. Change notes identify reference editions. This is a public reference pre-release,…
