monitor pcie bandwidth usage

[Elerek]

Is there any tool (windows or linux) that can monitor pcie usage / bandwidth consumption? 

I'd like to be able to see how close I am to maxing out the x8 connection my gpu has on my current rig.

unless you have a 1080ti i wouldn't bother. (PCIE 3.0 x8)

Unless you have 3 1080ti's running at 16 lanes there is no reason to fear about PCIe usage.

I'm not really worried about it, I just want to be able to see the bus usage.

GPU-z tells you the link's width as well as what generation it is.

That's not what I'm looking for. I want realtime data on bus saturation/usage.

i dont even believe there is a built in monitoring instance for that, so no tool can read it out... At least I have never heard of it.

I realize this thread is old, but I'm bumping it because it's a top search result on google.

 

I have recently discovered that RAGE, when run on a 750ti through a PCI-e 2.0 x4 port, has performance issues. But it doesn't when it's run through the PCI-e 2.0 x16 or x8 port on the same board. I would never have thought this could happen, as far more demanding games (even ones run in the same engine, such as Wolfenstein New Order) don't have any issues.

 

I would love to be able to see the rate of data going through the port, at any given instance, so that I could confirm whether or not RAGE is actually capping out the 2GB/s transfer speed of the PCI-e 2.0 x4 port.
