PCIe Speed Test v0.1 CPU-GPU/GPU-CPU bandwidth test

[Mechromancer]

Rig in sig, not overclocked, NB and core at stock, ran at 1066

Wow, your system looks like it's running fine, but at PCI Express v1.0 speeds and not 2.0 speeds. Run a GPU-Z and it should tell you if you GPU is running at version 1.0 or 2.0 PCI Express. With DFI, you probably have to manually set it in the BIOS. Let us know what you find.

Not sure what I'm looking for.....heh





EDIT:
This is what Everest tell me....

It looks like you are running at only PCIe 1.0 speeds. Congratulations! You can now unlock a lot of performance. Double check with the latest version of GPU-z though. My output looks like this:



The part highlighted in red is shoing I am running a PCIe v2.0 speeds.

I found it, wow......

WOW INDEED! Run some 3D benchies and let us know if your scores are a lot higher. It looks like your gaming rig is a lot healthier now.
