FAQs

Q: Does this riser require specific CPU or configuration?
A: PCIe lane availability can depend on the installed CPU(s) and system configuration; consult the server's slot mapping guide.

Q: What card sizes are supported?
A: Form-factor support depends on the chassis and riser orientation; verify clearance in the server quickspecs for the intended add-in cards.

Q: Is any license required to use the added slots?
A: No license is required; ensure system firmware is current for best compatibility.

Q: Are the PCIe links Gen5?
A: Link speed negotiates per system generation and device capability; the server supports modern PCIe speeds, with negotiation determined by both ends.
