Recorded variant and source limits

The 164-position x16 connector form does not by itself establish PCIe generation, lane enablement, bifurcation, power budget or motherboard behavior.
Product pitch and orientation do not constitute a fabrication drawing or slot-compliance gauge.

PICMG design-guide x16 reference slot: Source schematic contact identities A1-A82 / B1-B82. The two columns are schematic symbol sides, not a verified mating-face or solder-side view.

Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

Dark pinout view

What the status labels mean

Confirmed: Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source: Only one underlying document, or one pass, supports this assignment.
Device-specific: Supported for the named equipment or wiring only. Check your device’s manual.
Unverified: Missing or conflicting evidence. Do not wire from this row.
Not connected: The source explicitly says NC, no contact or no pin for this wiring.

B distinguishes connector-symbol polarity from deliberately inverted module-side nets; PICMG permits data-lane inversion. A13/A14 clock polarity remains unverified in B because PICMG and Mellanox disagree; data-lane inversion does not settle a clock conflict.

P261 PCIe x16 — **Partial; reference-clock conflict remains** — A's 3M Gen 5 extender and B's PICMG design-guide connector-symbol assignments agree on lane/contact placement after three transcription corrections described below. B distinguishes connector-symbol polarity from deliberately inverted module-side nets; PICMG permits data-lane inversion. A13/A14 clock polarity remains unverified in B because PICMG and Mellanox disagree; data-lane inversion does not settle a clock conflict. Modern 3M CLKREQ#/PWRBRK#/MFG/NC assignments differ from older guide reserved labels at B12/B30/A19 and other positions. Different documents; no universal revision-independent map.
This design guide is explicitly not a substitute for the PCI-SIG Card Electromechanical specification. No mechanical footprint or board mirror is supplied here.
A13/A14 reference-clock polarity conflicts between the PICMG guide and Mellanox manual remain unverified.
This is a source-scoped research map; PCI-SIG CEM normative revisions, later sideband assignments, exact card-side orientation and PCB termination mirrors were not independently established.

Unknowns stay unknown.

The 164-position x16 connector form does not by itself establish PCIe generation, lane enablement, bifurcation, power budget or motherboard behavior.
Product pitch and orientation do not constitute a fabrication drawing or slot-compliance gauge.
