hi i've assembled a new pc but when i install my gigabyte 4090 master into pcie 5.0 16x slot window freeze after 1 or two min.
the only way to solve the bug is downgrade it to 8x using pcie bifurcation 8x8 ( there is an other option to downgrade by bios to 8x ? i see nothing in bios).
i.m trying to force 8x installing a m2 drive to m2c slot (the upper one that share the lanes with pcie5 slot).
activating pcie bifurcation during cold boot system shutdown after 10 sec and reboot the all work fine.
someone can help me ?
