About the 330-BBOQ
The Dell 330-BBOQ is a Dell PowerEdge R740 PCIe Riser 3 Assembly (2x PCIe 3.0 Slots) designed to route PCIe expansion lanes from the motherboard to standard add-in card slots. Built with high-speed differential signal traces and physical PCIe slots, the 330-BBOQ expands server I/O capabilities while conforming to internal chassis airflow ducting.
Compatibility
Engineered specifically for Dell PowerEdge R740, R740XD servers, the 330-BBOQ installs into dedicated chassis riser positions. The 330-BBOQ connects to motherboard PCIe headers and provides physical PCIe slots with full electrical lane allocations as configured by the server system architecture.
How to identify a genuine unit
Authentic Dell riser boards feature a serialized label showing DP/N 01CN1N, riser position markings (e.g., Riser 1, 2, or 3), and PCIe slot mechanical/electrical designations. The sheet metal bracket of the 330-BBOQ is shaped for precise alignment in the server chassis.
Buying used
When sourcing a used 330-BBOQ, inspect the PCIe slot connectors and gold-plated blind-mate edge fingers for physical damage, scratches, or bent contacts. Verify that the metal mounting bracket on the 330-BBOQ is straight, that retention latch clips are unbroken, and that add-in cards seat firmly into the slots.
