Why a GIG PHY only works in 100M mode

Hi guys:
I was stuck..
My GIG PHY can only work at 100M mode.
At 1000M mode, PHY can only receive ,but can not transmit
data.
I am sure software and driver are right,and all TX and Rx
lines are terminated, clock is OK.
Could anyone provide advices?
Thanks a lot

Ask on a computer newsgroup.

The TX clock for gig goes the other way and is on another pin (probably
called something like GTXCLK).
