PCI express stuck at x1. Any help?
The first thing to check is: is the card in a PCIe 16 slot? Usually, the PCI 16 slots are close to the CPU and colored differently from the normal PCIe slots.
When your card is idlleing it will automaticly drop the bus speed down to x1 as part of the power svaing feature as soon as your gaming again it should automaticly go back up to x16 on it’s own.
We need to know what motherboard you’re using before any accurate response can be made. (This includes which slot the GPU is slotted in)
