Dell PowerEdge R520 Riser Boards
The Dell PowerEdge R520 server uses two (2) different riser boards featuring PCIe slots for up to four (4) adapter cards. PCIe connectivity is integrated with the processor in that the number of processors in a system impacts the number of PCIe slots and the bandwidth of each PCIe slot.
- Riser board #1 features one (1) x16 PCIe 3.0 half-length, half-height slot with x16 bandwidth when two (2) processors are installed. When only one (1) processor is installed, the slot is becomes a PCIe 2.0 x8 connector with x4 bandwidth.
