bus interface on Radeon R7 M440 should be 3.0x8 but it is actually 3.0x4

hi guys.

i have bought a HP notebook 15-Ay044Ne with Graphics card radeon R7 M440 the problem is that in the specification of the graphics card's bus interface is : PCIe 3.0 x8 but it is actualy Bus Interface: PCIe 3.0 x4 so the performance is soo weak and lower than i expected

so i need someone help me to increase it from x4 to x8

How do you know it is x4 and not x8? Assuming you are right there is not going to be any way to change it. If you can show that it is advertised as an x8 slot and is actually an x4 then I would think you are entitled to return it for refund, but I cannot commit HP would do that.

in radeon settings/ hardware it is mentioned PCI Express 3.0 X4 however, on site like techpowerup.com and it's app mentioned it support 3.0X8 but its current is 3.0 x4  for me it doesnt matter any more someone told me even if it was x8    R7 M440 card is weak and i wont feal the differance 😕
