Lenovo 4X67A86438 ThinkSystem SR655 V3 GPU Enablement Kit

Overview

The Lenovo 4X67A86438 is a GPU enablement kit designed to unlock discrete GPU support in the ThinkSystem SR655 V3 rack server. If you're expanding an SR655 V3 for GPU-accelerated workloads — AI inference at the edge, high-density video analytics, or compute-intensive security applications — this kit provides the internal hardware components required before a GPU card can be installed and recognized. Without it, the server's mechanical and power delivery configuration does not support add-in GPU cards. The 4X67A86438 ships at 2.00 lb, reflecting internal riser or cabling components rather than a standalone card.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR655 V3 platform. This kit is not cross-compatible with the SR655 V2, SR645, SR665, or other ThinkSystem 2U/1U platforms — chassis geometry, power routing, and PCIe riser layouts differ across generations. Verify your server's exact model designation (SR655 V3) and existing riser configuration before ordering. If you are deploying GPU acceleration across a rack of rack servers, confirm per-node kit requirements with your pre-sales engineering contact, as GPU slot count and PCIe bandwidth allocation vary by SR655 V3 build configuration.

Installation Notes

Installation is performed inside the SR655 V3 chassis with the server powered down and removed from the rack. Standard ESD precautions apply when handling internal riser and power components. Consult the SR655 V3 Hardware Maintenance Guide for torque specifications on riser bracket fasteners and PCIe slot sequencing rules — GPU slot priority affects which physical slots are active post-enablement. No external tools beyond a standard screwdriver set are typically required, but confirm against the server's service manual for your specific build configuration.
