How to test what speed my PCIe card is running at?

[Mars999]

I need to determine if one of my cards is running at 4x or 1x in my system. Is there any software to check this?

Thanks!

GPU-Z will tell you the bus interface, does that help?

CPU-Z tells me what link speed the graphics card is running at (link width), as well as the maximum bus speed (max supported). A while after I built the machine I'm currently using, I discovered (through this program) that I had the graphics card in the wrong slot for optimal bandwidth.

I need one of my add in PCIe controller cards tested... Not my Gfx card...

Are you talking about your Asus Xonar DX PCIe? If so, that is a PCI Express x1 card. If you're talking about another PCI Express x4 card then it must be in the black PCI Express 2.0 16x slot to enable 4x speeds.

Yeah I know it's a PCIe 1x card, but with my gfx card in a 16x slot, the Xonar in a 1x slot, my ASUS U3S6 card is a 4x card. IIRC the P67 boards only allowed 20x lanes worth so I am guessing I am not running 4x with the U3S6 card?

As I said, it needs to be in the black PCIE 16x slot to get 4x speeds. You're looking at it as if all lanes are maxed graphics using 16 + Xonar using 1 + U3S6 using 4 = 21 That's not how it works. Your U3S6 is running at 4x.

Now that we've gotten that out of the way, what is the problem you're having?

ssd speeds on that u3s6 aren't to hot...

you can check from BIOS system by pressing DEL key.
