• Two PCIe 4.0 x16 slots for full-height, full-length add-in cards
• Supports PCIe Gen4 devices with up to 16 GT/s per lane
• Internal riser card for Riser 2 position; no hot-swap support
• Kit includes riser card and necessary mounting hardware
• Operating temperature: 0°C to 55°C (server environment dependent)
• Humidity range: 8% to 80% non-condensing

Why choose it

This genuine Lenovo riser kit ensures exact fit and reliable signal integrity in SR665 servers. The dual x16 Gen4 slots unlock maximum bandwidth for demanding accelerators, enabling faster data processing and smoother virtualisation. Its server-specific design simplifies installation and maintains proper airflow for consistent thermal performance.

Ideal use cases

• Adding dual GPUs for AI training or inference in rack servers
• Installing high-speed network adapters for 25/100GbE connectivity
• Expanding storage with NVMe controller cards
• Upgrading existing SR665 systems for new PCIe workloads

Good to know

The riser card is not hot-swappable; power down the server before installation. It is intended for the Riser 2 slot and may require additional cables depending on the add-in cards used. Always verify server machine type (7D2V or 7D2W) before ordering.
