Check PCI Express (PCIe) Slot Width
Dual-port 600 Series devices require a PCIe 4.0 x4 interface, using 4 PCIe lanes. Quad-port 600 Series devices require a PCIe 4.0 x8 interface, which is bifurcated into groups of x4, using a total of 8 PCIe lanes.
The table below summarizes the required slot width, lane usage, and slot speed for 600 Series devices.
| Device Type | Slot Width | Lane Usage | Slot Speed (per lane) | Notes |
|---|---|---|---|---|
| Dual-port 600 | x4 | 4 lanes | 16 GT/s | Requires full x4 bandwidth at Gen 4 speed |
| Quad-port 600 | x8 | 8 lanes | 16 GT/s | Bifurcated into 2 x4 groups at Gen 4 speed |
