FAQs

Q: What is the difference between Riser 1 and Riser 1B?
A: Riser 1 typically provides a mixed x8/x16/x8 layout, while Riser 1B provides three x8 slots routed to CPU1, often used in GPU-focused configurations.

Q: Does this riser include GPUs or power cabling?
A: No. It includes the riser only. GPUs, power cables, and brackets are separate options.

Q: Will using Riser 1B increase PCIe bandwidth?
A: No. Bandwidth is determined by CPU and platform lanes; the riser presents those lanes to slots.

Q: How do I confirm GPU compatibility?
A: Consult the system’s configuration guide and validated option list for supported GPUs, power, and thermal requirements.
