You're expanding a ThinkSystem SR665 and the Riser 1/2 position needs to carry three cards at different lane widths. One x16, two x8. That's not a one-size-fits-all slot — it's a specific riser geometry, and you need the OEM kit that matches it. This option kit is built for exactly that: PCIe Gen4, x16/x8/x8 split, Riser 1/2 position. No bending a Gen3 card to fit a Gen4 lane. No third-party riser that's two millimetres off and won't seat. If your SR665's been waiting on the right expansion part to go live, this is it. Add to cart
