[SOLVED] GPU not using PCIe 3.0

[GemblanFelicis]

Hello. I am using NVIDIA GTX 1050 Ti with i3 3240 on ASUS p8h61-m lx3 r2.0 motherboard which supports PCIe 3.0
but my 1050Ti is only using 2.0 at max even when am playing games. Does anybody know how to solve this I have already
checked in bios but there is no option for changing PCIe gen version.

What are you using to determine that it is running at 2.0?

gpuz and nvidia control panel

It doesn't matter in the end, the 1050Ti is a low end card, it won't use the full bandwidth of 3.0 on x16 slot. If the card is on the x16 slot even 2.0 will provide enough data transfer for it.

You can also check the bios to adjust the gen levels for each pcie slot/lane. Usually it's set to auto so it probably set itself to 2.0 to reduce power use.

Feels bad to be at the low end eh?

It doesn't matter if it is low end or high end gpu card PCIe 3.0 provides more fps and better connection... I have already checked the bios there is no option for changing PCIe gen version...

No, not really. Most of the time there will be little to no performance difference between PCIe 2.0 and 3.0. The difference you do see is typically loosely correlated with FPS, so weaker GPU means less FPS means less performance impact.

Were you running any kind of GPU load when you were looking at PCIe link speed? There are power saving features that can step down the PCIe speed/connection width under low load. This is explained by the little question mark tooltip next to the PCIe link field in GPU-Z.

It doesn't.

^ What he said. Also check nvidia control panel settings and set your power settings to performance as well.

As you can see from this video there are diff from 3-5fps and vram and ram consumption. In some other videos I have found even 5-10fps so yes there are still diff it's small but it is.

As I have write in question GPU under load didn't go over 2.0 and yes am using performance option in nvidia control panel.

Could you post screenshots of the CPU and Mainboard tabs in CPU-Z?

Your mobo doesn't have PCIe3.0. You'd need a 7x series board for that.

I'm pretty sure 6 series boards should still support PCIe 3.0 as long as you have an Ivy Bridge CPU. The PCIe controller for the x16 slot is on the CPU, not the motherboard. The specs for their mobo list the slot as being PCIe 3.0/2.0.

 

[tennis2]

Oh, my bad. I thought that was only the 7 series boards.

Your processor only supports PCIe 2.0.

As said above it's not going to make a difference though.

Oh ok thanks
So will i5 3470 support 3.0, do I need to update my bios or something

Yes, although I wouldn't necessarily get a 3470 (definitely not just for the sake of PCIe 3.0) unless you can find one for really cheap. You shouldn't need to update the BIOS, although doing so wouldn't hurt.
