[操作疑難] DMI frequency?

本帖最後由 darkfrank 於 2014-5-6 20:03 編輯

想問下haswell + z87下如何知道 DMI行緊幾多frequency?
因為見塊M6G有D voltage setting 係 set according to high dmi or low dmi
唔係太清楚個關系
Thanks

from ROG Guide

PCH ICC Voltage: Voltage Rail of the Integrated Clock Controller. Default is 1.200v and sweet spot depends on the DMI Frequency used.

High DMI’s sweet spot (eg in excess of 115MHz) is around 1.2500v or lower.

Low DMI’s sweet spot (eg lower than 86MHz) is around 1.7000v or higher.

DMI GEN2 can be disabled when targeting BCLK above 200MHz. (i.e. DMI Frequency >= 120MHz) can help to trade the CPU to PCH link performance with more room for high BCLK O.C.

例如呢項又話BCLK > 200MHZ = DMI 120MHZ?
我想知DMI frequency個關係系點？
