最后一个PCI-E的LANES CONFIGURATION选项是用来拆分插槽通道,以便于支持更多扩展设备。不过拆来拆去都会折损显卡插槽的通道噢。 如果是B550平台,那只要把PCI-E1的最大速度设置正确即可,因为B550平台只有第一根显卡插槽为PCI-E 4.0。而Z590主板也是类似设计,第一条x16为4.0规格,其他均为3.0。 怎样判断通道正确 PCI-E...

1. CPU Mode – if you switch M2_2 and M2_3 lane source to CPU mode, the slots are running at PCIe 4.0 x4. However, if M2_2 or M2_3 is populated, it’ll use x8 lanes from the CPU and therefore a graphics card installed in PCI_E1 is running at PCIe 4.0 x8. ...
Because lanes are self-clocking and stacking the lanes requires data buffering in order to reassemble words, the scheme is highly tolerant of skew. At the highest levels of system activity, PCIe retains compatibility with standard PCI. They use the same configuration register definitions and ...

使用 128b/130b 编码模式意味着通道(Lanes)现在传输的是 8 bits/byte,而不是 10 bits/byte,这意味着 Gen3 只需要 8.0GT/s 的数据速率,就能够相比 Gen2 增加一倍带宽,相当于链路收发双向上的带宽为 1GB/s。 为了说明这两种编码的区别,首先考虑图 12-1,它展示了 8b/10b 编码模式下数据包的一...
