من X370 Pro داشتم، مادربردت سالمه، مشکل اینه پردازنده ای که داری 2200G، فقط از 8Lane آن هم فقط برای یک درگاه PCIe پشتیبانی می کنه، بنابراین کاملا طبیعیه که اسلات دوم گرافیک کار نکنه. اسلات آخر منشعب از Chipset هست بنابراین باید کار کنه.
اسلات وسطی باید Disable باشه مادامی که از پردازنده ضعیف 2200G استفاده می کنید.
Apparently, these chips feature just 8 PCI-Express gen 3.0 lanes for discrete graphics, besides 4 lanes dedicated as the chipset-bus, and 4 other lanes driving a 32 Gbps M.2 NVMe slot. What this means for the end-users, is that any discrete graphics cards plugged into the PCI-Express 3.0 x16 slot will run at half the bandwidth - PCI-Express 3.0 x8.
This, however, becomes a problem for the small minority of users who combine these processors with AMD X370 chipset motherboards. The second x16 slot (which draws its PCIe lanes by segmenting it from the first x16 slot) won't work
