Hello @notsofunny90 

Thank you for reaching out to us.
After reviewing the specifications in the ROG STRIX Z390-E GAMING user manual and confirming with the relevant teams, we have verified that when a GPU is installed in the PCIEX16_2 slot while leaving PCIEX16_1 unoccupied, the slot will still operate at a maximum speed of X8.

If you require full X16 operation, we recommend verifying the functionality of the PCIEX16_1 slot by cross-testing with another GPU, trying updating the BIOS, and clearing CMOS. If you suspect that the PCIEX16_1 slot may be damaged, please evaluate whether sending the motherboard for repair is necessary.
For further assistance, please contact our local service team in your region for support.

Thank you.
