pci-e lanes

[Rixoder]

hey I have a gtx 1650 (g6) and an asus prime b450m-k mobo and a ryzen 3 1200 and wich both support pcie-e 3.0 16x my gpu only seems to be using 4 pcie 3.0 lanes (according to gpu-z) is there a way to allocate more? (I have no nvme) just 4 sata devices and no pcie-e expansion slots are being used

Look in your MoBo manual.

Are you using a slot that is wired for 4x?

Irrelevant how many sata and nvme you use, they're separate from pci-e slots.

 

Your pci-e x16 slot gets 16 pci-e lanes from the cpu, if you had a second pci-e x16 slot that would have received pci-e lanes from the chipset and usually that slot only gets 2 or 4 lanes.

It will only use x4 lanes when idle and ramp up to x16 when loaded.

 

Even if it didn't, the GTX 1650 is a very low end card, it probably would work fine at x4.

Only 1 pci-e slot on the mobo

Thanks for all the answers after seeing some vidoes on yt about the performance loss it was about 2 fps or so as you said so i decided its  just not worth the hassle
