Is My Card Running In PCI-E 1.0 Mode?

[Overslop]

I am running a 4890 Crossfire Setup.

Using GPU-Z, everything appears to be normal. Except for the Bus Interface that is.


The first card displays as: PCI-E 2.0 x 16 @ 16

The second displays as: PCI-E 2.0 x 16 @ 16 2.0


That suggests to me that the first card is running in PCI-E 1.0 mode. Or is it just slot 1 and therefore no 2.0?

If it is running at the wrong PCI-E speed, how can I fix it? I had a check in the BIOS and didn't find anything relating to that other than PCI-E 1.0 or 1.0a. I have tried both, and they don't effect the reading.

I am pretty sure the cards are in the correct slots on the motherboard...

Use GPUZ, it'll tell what each card is running.

Probably nothing you can do to fix it - possibly try swapping the cards over to see if its a slot or card specific issue...

But tbh I wouldn't worry about it - its not like its going to have ANY impact on performance.

I am using GPU-Z to get those figures.

So was I right then? - It is running in PCI-E 1.0 mode??

Does anybody know?

if its the motherboard in your sig, then it will run both cards at 2.0 16x

If it is working correctly.
