pcie slot speed issues....

Hi all,

Before I start moving cards around all over the place I wouldnt mind finding out if there is an easy answer to this..

I have 3 G Cards on my board at the moment (i know it doesnt support SLI but will be folding at the moment then changing board)

GTX 280 AMP is running in top PCIE slot at 2.0 x16 = This is good

2nd slot GTX280 is running at PCIE x16 but v 1.0

3rd full length slot 9600GT is running @ 8x PCIE 1.0

Is having 3 cards affecting how these cards run at 2.0?

Should they all be 2.0 or not?

Going to our last section on the board, we have the expansion slots as well as the additional controllers that come with it. The board has all green slots so there aren’t any different colour coding patterns for each type of slot. The board comes with a total of three PCI Express x16 slots for graphics; the top and middle slots run off the X48 Northbridge and both run at full x16 speed with PCI-E 2.0 spec support. The last PCI Express x16 slot runs off the Southbridge for adding in a third graphics card for Physics. A single PCI Express x1 slot makes up the last of the PCI-E expansions.

If you want to use the last PCI Express x16 slot at the full x4 speed, you can’t use the PCI Express x1 slot without the last PCI-E x16 slot going back to x1 speeds. Lastly on the expansion slots there are three legacy PCI slots; hopefully soon we will see the end of PCI on motherboards and the addition of more PCI Express lanes to Southbridges that Intel release.

Looks like the software your using in reading the settings incorrectly. Are you using GPU-z or something else?

GPU Z

Just rebooted now both GTX's running at 2.0 and GT running at x16 PCIE 1.0

So all working now...

Maybe just needed a reboot as I had onlly just setup
