The IBM 43V7066 PCI-X / PCIe Riser Board is an enterprise server expansion riser used in IBM System x series platforms. It provides a vertical or horizontal interface that allows PCI or PCIe expansion cards to be installed in compact server chassis where standard slot placement is not possible.

This riser board is commonly found in IBM System x3550 and x3650 generation servers, enabling support for additional network adapters, storage controllers, or other PCI/PCIe add-in cards within a space-constrained 1U or 2U server design.
