Thanks。I've tried it on other hosts,like intel CPU, and it links to 8GT/S。It links to 5GT only under PLX8748。But other boards can link to 8G under this 8748。

Hello JYu3,
That is what we are trying to figure out. We want to know the model of the system for us to check the specification of the system.

Hello JYu3,
There is a lot of possible causes and I need to further check everything before I provide a recommendations. The issue that we are facing is that since it is embedded in a system, the OEM or system manufacturer may have altered the specification of the NIC.
If you have questions, please let us know.

Thanks。It can trained to 8G by linking disable and enable at 8748 downstream, but it was unstable. And it is useless after retrain, it's still 5G.

Hello JYu3,
I understand. However for further assistance and troubleshooting, it is best if you can contact the manufacturer of the system or the board. They may have altered this NIC and those changes are unknown to us.
If you have questions, please let us know.
