Hi everyone. I have a strange problem with my 1050 Ti, in GPUZ and HWinfo it shows that it is running on PCIE 1.1 but my motherboard supports PCIE 2.0.
I have all the newest drivers installed, the bios is updated to the latest version, the GPU is in the correct mobo slot. Here is a screenshot providin most needed info, btw in the screenshot im running GPUZ rendering test.

Ah so bios does say PCIe2 when you select the x16 slot which I'm assuming means it's PCIe 2.0x16. Question is why is gpu-z not reading it as such. If you put some load on it, like run a game, and then check in gpu-z, is there any change?

It's not only gpuz, Hwinfo also reads link speed at 2.5GT/s, pcie 2.0 speed would be 5.0GT/s.
Does lower link speed have any impact on this gpus performance?

Actually I may be wrong about my assumption as your manual lists the top x16 slot as PCIe2 and bottom one as PCIe4.
Lower link speed does have effect, however, it may be downshifting if you're not pushing the card. Hence why I suggest trying with a game.

I've seen ram not running in dual channel mode can have this effect. In fact even cuttin the bandwidth in half. Even if it is running @ pic-e 1.1 speed your not gonna lose any bandwidth. At the most 1%. There's truly no real world difference between the 3. (On a card that's 112GB sec.) But i can see how something like that might drive a person PC Krazy. I have a 1050ti on a ol'school evga 680i sli board with a pic-e 1.1 lane. and even though it's rated at 2.5GB transfer speed, a program I'm using (HW64) says It's getting close to 4GB (3.9GB) interlink Bandwidth. Every computers different. I'll see if i can get a straight answer about these pci-e bandwidth speeds on dif. chipsets and cpus.
