CYPRISER3RTM Intel Riser Card

High-Density 1U Passive PCIe Expansion Riser Card for low-profile add-in cards with the CYPRISER3RTM

The CYPRISER3RTM is an Intel 1U RHS passive PCIe riser card engineered to extend PCIe Gen-ready expansion in space-constrained rack servers where low-profile adapters are mandatory. By mapping a single PCIe x16 host interface into two low-profile PCIe x8 connectors, the CYPRISER3RTM enables clean integration of high-bandwidth I/O devices while maintaining predictable lane allocation and chassis airflow constraints typical of 1U platforms.

As a passive design, CYPRISER3RTM relies on the server’s CPU/platform PCIe root complex and board-level signal integrity rather than adding a retimer or switch layer. This architecture supports deterministic latency characteristics and reduces component complexity for NIC, HBA, and RAID adapter deployments. The mechanical RHS placement and 1U profile are optimized for compact server layouts; however, the CYPRISER3RTM is intentionally not suited for full-height or full-length GPU installations because both downstream slots are low-profile only.

Why Choose the CYPRISER3RTM?

The CYPRISER3RTM delivers a practical density-to-performance balance by converting limited 1U internal volume into two standardized low-profile PCIe endpoints without altering the platform’s PCIe topology beyond lane bifurcation. It is a dependable choice for scaling network or storage connectivity in clustered deployments, where consistent slot geometry, repeatable cabling/airflow paths, and serviceability are critical for operational uptime.

Intel’s engineering approach focuses on validated mechanical fit, enterprise-grade interoperability, and alignment with modern rack server design constraints. CYPRISER3RTM is built to integrate smoothly into supported Intel server ecosystems, helping maintain compliance with platform power, thermals, and service procedures in production data centres.
