Z87/Z97的PCIE只剩X6 不是沒動嗎?查看其他資料也是x8

========================
DMI 2.0 check intel datasheet got this:

Four lanes in each direction
5 GT/s point-to-point DMI interface to PCH is supported

Raw bit-rate on the data pins of 5.0 Gb/s, resulting in a real bandwidth per pair of 500 MB/s given the 8b/10b encoding used to transmit data across this interface. Does not account for packet overhead and link maintenance.

Maximum theoretical bandwidth on interface of 2 GB/s in each direction simultaneously, for an aggregate of 4 GB/s when DMI x4

wiki上面寫的怪怪的...
