Ok so after 4 faulty boards from gigabyte i've changed my bubbleless i7 builds motherboard to a ASUS Rampage Extreme II I set it all up and got to vista to only find it saw two of my three GTX280's. I have tried different drivers and I am currently about to ring ASUS about it. Has anybody got any ideas.

I know all three cards are good.
The board does support tri-sli.
The BIOS's option to change the PCI-E configuration is disabled?
I am also running the Supreme FX Soundcard PCI-E.

1)Start by taking out the PCI-E supreme FX just to see if it resolves the problem.
2)Check that you have the latest bios / drivers installed.
3)Contact Asus about it

Yeah, 4 faulty gigabyte motherboards is unbelievable bad luck.
Btw: It's the Rampage II Extreme, not Rampage Extreme II.

Latest BIOS? And do you have the correct Tri-Sli Bridge? (Silly questions, I know)

If not, don't worry. Scan are great about Warranty and RMA, they are the Newegg of the UK.

Just putting the latest BIOS on now, got the SLI bridge and I may have a had a different Scan RMA experience.

Just finished playing around with different drivers and the new BIOS.
Hasn't made a difference, tried ringing ASUS but they just had a machine saying to goto the website and then hung up, tried scan but I couldnt get through to anyone so gonna try a graphics card in each slot soon. Just need to sort out for draining the loops.

I have a feeling I've got another bad board

Try BIOS 1001. For me it seems like the most stable version. You sure you can't change the PCI-E lane to x8 x8 under NB configuration? The default is at x16 x1 so that might be your problem.

Im just having a play with the order of the cards in different slots.

I was looking into Trip SLI myself...however I believe if you have the X1 Sound card in the first X1 Slot, you cannot do Trips SLI...Look in the ASUS Book that comes with the MB, I believe it explains that there...I can get 16x 16x X1 by default with Dual 260 GTX, and the X1 sound card installed.
