P5Q Pro PCIe running x8 not x16, why?
 
I'm running my P5Q Pro with one video card.

I have my sound card in the black PCIe slot. Could this be why my blue slot is running half speed?

Is there a way to have my Blue slot run at a full x16, while having my sound card in the black slot?
It would be nice to do so, it makes for better airflow.

Thx all!

I think whenever you plug something into another PCI-e x16 slot on boards like that it dials it down to 8x/8x.

There is not much you can do about it other than populating another PCI-e x4.
With those boards, they are capped out at 8x 8x when both are in.

Just design.

Darn I was afraid of that.

Oh well, I have an empty PCIex1 between the GFX card and where the sound card is now.

Thx for the quick reply. :thumb:

No problem.

If I recall Correctly , you need a board with full Electrical X16 Slots to Run 16/16.
That board has whats called Mechanical Slots (Someone correct me if I'm wrong).

So if you ever are looking to upgrade the board, look for that in its specs.

Cool, thx!

Luckly I was never planning to crossfire and moving my soundcard over isn't having much of an impact in my case, but that's definitely something I shouldn't have missed in my research. Oh well as long as I learn...

You don't loose nothing if you run your video card at PCI-E 2.0 x8.

I wouldn't say that if i were you, theres a reason people buy x48 chipsets for crossfire
