Hi, this has been really hard to find an answer to so here goes... the GPU-Z tool is reporting of of the GPUs in my GTX 295 as running in PCI-E 2.0 but it should be running in PCI-E 1.1 or whatever, this doesn't make any sense to me and I was wondering if it is incorrectly installed and slowing down my graphics ability...

1. Is it me or does your title conflict with the text of the post ?

2. What does the MoBo support ?

Ah sorry about the title...
I have an ASUS 780a and it has 3 x16 PCI-E ports, seeing as the 295 only uses one it just seemed strange that one is reported as supporting PCI-E x16 v1.1 but is running in x16 v2.0 I didn't understand because the two GPU's are in the same card and only use 1 slot.

an Nvidia 780a SLI board has 2 x16 2.0 slots and 1 x16 1.0 slot, as I recall

The strange thing is that the card takes up one x16 slot, yet one of the GPU's is reporting as being only x16 v1 compatible

Is it possible the card being listed as v1.1 compatible only is installed in the slot that's only v1.1 compatible?

i think we have a communication break down so let me see if we can all get on the same page

you are running two GTX295 cards on a Nvidia SLI board. GPU-Z states one card is on a PCI-E 2.0 slot while the other card is on a PCI-E 1.1 slot. Is that correct? If so...

then if you want, just move the GTX295 card on the 1.1 slot over to the free 2.0 slot you have. If it can't fit because the slot is covered by the 1st GTX295, no worries. Its not a major performance issue.

I tihnk he is saying that each of the GPUs in his single 295 is being identified differently. one as PCI 2.0 and the other as 1.0.

sounds strange, but its most likely just an error with the GPU tool, not the card. obviously both GPUs are using the same interface, you cant change that.

then that is just how the 295 was built, like you said you can't change that.
