ASUS規格寫得很清楚!!
====================================
2 x PCIe 2.0 x16 (single at x16 or dual at x8/x8 mode)
1 x PCI Express 2.0 x16 slots (at x4 mode, 2.5GT/s)
2 x PCI Express 2.0 x1 (2.5GT/s)
====================================
1.當藍色與白色PCI-e x16都有插卡時,都會降至 x8.
2.黑色的PCI-e x16雖有x4,但只有2.5GT/s...跟PIC-e x1頻寬一樣!!
