CPU: Intel Core i7-14700
Motherboard: ASUS PRIME Z790-P WIFI
BIOS Version: 1641
I installed two ASUS XG-C100C 10G network cards in several PCs for manufacturing line. One is installed on PCIe bus PCIEX16(G4)_1 and the other is installed on PCIEX16(G4)_2. The driver version XG-C100C is 3.1.6.0.
If the PCs are not used for several days, sometimes PCIe link speed of XG-C100C could be changed from 16 GT/s to 2.5 GT/s. Here are the screenshots of HWiNfo
I google this problem and found some solutions, and changed following system and BIOS settings:
However, this problem still occurred after several days.
The only way to recover its PCIe link speed is to restart the PCs. Is there any other method to fix it permanently?
Any suggestions would be appreciated.
