## Summary description

Riser kit for Lenovo ThinkSystem SR665 designed for 2U chassis, providing x16/x16/E PCIe Gen4 expansion slots. This riser enables installation of additional PCIe cards in the SR665 server, supporting high-bandwidth devices such as GPUs, NICs, or accelerators. Suitable for system upgrades, expanding I/O capacity and improving compute or networking flexibility.

## Long description

The PCIe Riser Kit Lenovo ThinkSystem for SR665 — 2U x16/x16/E PCIe Gen4 is a server component designed for the Lenovo ThinkSystem SR665 2U chassis. It provides two full-length x16 PCIe Gen4 expansion slots plus an auxiliary x16/x8/e slot configuration, enabling installation of additional high-bandwidth add-in cards such as GPUs, network adapters, and accelerators. The riser is engineered to match the SR665 mechanical and electrical interfaces so that expansion cards operate at PCIe Gen4 throughput when paired with compatible CPUs and motherboard traces.
Advantages
This riser kit increases system expansion capacity without modifying the mainboard, allowing flexible placement of multiple PCIe cards in a compact 2U server. By providing Gen4 signaling on x16 connectors, it supports high-bandwidth devices and reduces potential I/O bottlenecks. The kit is built to meet server-grade reliability and thermal constraints typical of rack servers, enabling stable operation under load. Installation maintains proper airflow paths within the chassis and preserves compatibility with Lenovo ThinkSystem SR665 mechanical mounting points.
Suitable for
Upgrading SR665 servers to add GPUs for AI/ML inference or compute acceleration
Expanding network I/O by installing additional NICs or converged network adapters
Adding storage or NVMe accelerator cards to increase throughput for data-intensive workloads
System refreshes where additional PCIe expansion is required without changing chassis
Key specifications
Form factor: 2U server riser compatible with targeted 2U chassis
Slot configuration: two full-length x16 PCIe Gen4 slots plus an auxiliary x16/x16/E arrangement
PCI Express generation: Gen4 signaling for high-bandwidth cards
Connector types: standard PCIe x16 mechanical edge connectors
Electrical lane support: up to x16 lanes per primary slot (subject to motherboard routing and CPU capabilities)
Mechanical mounting: designed to match SR665 riser board mounting points and retention brackets
Thermal considerations: server-grade design to maintain airflow and heat dissipation in 2U chassis
How to use
Power down the SR665 server and disconnect power and external cables before installation. Remove the chassis top cover and locate the riser bay designated for the replacement or addition of the riser kit. Align the riser with the motherboard riser connector and the chassis mounting points, then seat the card into the riser connector until it is fully engaged. Secure the riser to the chassis using the original retention screws or brackets. Install desired PCIe cards into the x16 slots, secure them to the chassis bracket, and reassemble the server. Reconnect power and peripherals, then power on and verify that installed devices are recognized at the system firmware and operating system levels. Ensure firmware and drivers are updated for full Gen4 performance.
Usage recommendations
For best results, use this riser with PCIe Gen4-capable CPUs and firmware that support Gen4 lane speeds. Confirm card heights, bracket types, and power requirements before installation, and ensure adequate cooling for high-power devices such as GPUs. Follow Lenovo service manuals for torque and seating procedures to maintain warranty and system reliability.
