gpu at "PCIe x 16 2.0 @ 16 x 2.0"

[dfsgsfa]

i moved the gpu , gtx970 msi gaming, to a old pc i5 2500, h61 mobo, 2x4 gb ram, 4x sata drives

(same setup with rx570 showed pcie 16 x 3.0)

 

and i checked gpuz and it showed 2.0 instead of 3.0

Put some load on the GPU.   Also make sure it's in the right slot, as only one is 3.0.

 

Honestly even if it's running in 2.0 mode, that's fine.  It's way more than enough bandwidth.   It would take a 1080 Ti or higher to (just barely) use up the bandwidth of a 2.0 x16 slot.

I think it's the 2080Ti that was shown to exceed 1/2 of the PCIe 3.0 bandwidth, equivalent to PCIe 2.0 x16.

 

Gamers Nexus measured this with SLI 2080Ti's if I recall.

It made some small difference in some games on the 1080 Ti too, but there wasn't much difference between the Pascal and Turing architecture.

This is because PCIe 3.0 was introduced in Ivy Bridge motherboard. Sandy Bridge (H61) is only PCIe 2.0

Exactly. I looked up both the chipset and CPU, and both of them only support 2.0. Thus, OP, your card is showing up as PCIe 2.0 because it's connected via 2.0, even though the card itself is still 3.0-capable.

Much like USB, or SATA, or other backwards-compatible standards, the lowest specification wins.

h61 only has 1 x 16 slot

my other gpu rx570 showed x16 , 3.0 on same mobo, cpu, drives setup

 

if its fixable, i would like to fix it and know what caused it

The PCIe version isn't based on chipset or motherboard it's based on CPU. Sandy Bridge CPU i5 2500 only supports 2.0. How to get it on your motherboard? Upgrade CPU.

There is nothing wrong. Your CPU and Motherboard only support up to PCIe 3.0
If you really want PCIe 3.0, you need at very least a different motherboard and CPU.

PCIe 3.0 also requires the Motherboard to support the higher speed. Installing a PCIe 3.0 capable CPU will not enable it on a motherboard that doesn't support it.
