About the 330-BCOM
The Dell 330-BCOM is a Dell PowerEdge R750 PCIe Gen4 Riser 2 Assembly (3x PCIe 4.0 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-BCOM expands server I/O capabilities while conforming to internal chassis airflow ducting.
Compatibility
Engineered specifically for Dell PowerEdge R750, R760 servers, the 330-BCOM installs into dedicated chassis riser positions. The 330-BCOM 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 012DJ8, riser position markings (e.g., Riser 1, 2, or 3), and PCIe slot mechanical/electrical designations. The sheet metal bracket of the 330-BCOM is shaped for precise alignment in the server chassis.
Buying used
When sourcing a used 330-BCOM, 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-BCOM is straight, that retention latch clips are unbroken, and that add-in cards seat firmly into the slots.
