    Exclamation GPU Stuck in x8 ONLY on PCIEX16_1

    I've recently updated BIOS to 1302 because GPU was running at x8 in the PCIEX16_1 slot. After update BIOS, GPU-Z and CPU-Z all still show that it runs PCI-E 3.0 @ x8. Running GPU-Z render test or UNIGINE benchmarks doesn't help. It still shows PCI 3.0 @ x8. Clearing CMOS, reseating GPU didn't help. Running BIOS at optimized defaults didn't help. I'm running out of options here. Important to note that I do not have anything else plugged into the PCIEX16_2 or _3 slots.

    Here are my specs:

    OC'ed? No.
    Motherboard: Asus ROG MAXIMUS X HERO (WI-FI)
    CPU: Intel Core i7-8700K
    AIO: Thermaltake RIING 360 RGB
    RAM: Trident G. Skill RGB 32GB (4 x 8GB) DDR4-3000
    M.2_1 Slot NVMe (Boot): Samsung 960 PRO 512GB M.2-2280
    M.2_2 Slot NVMe (Games): Samsung 960 EVO 1TB M.2-2280
    SATA_1- Used, WD Black 1TB
    SATA_2 - Used, WD Black 1TB
    SATA_3 - Used, Toshiba X300 5TB
    GPU: EVGA SC2 Hybrid GTX 1080 Ti 11GB
    PSU: EVGA SuperNOVA P2 1000W

    Thank you for your help!
