well for some reason my second 16x pci-e slot doesn't seem to work.
m3n ht deluxe 780a chip.
i can run sli in the first 2 slots, but it runs at 16x/8x (the cards are right on top of each other so the top card is running 10c hotter.)
2x260/216 cards.
if i run a single card in the second 16x slot i get no picture.
also if i run 1 card in the main slot all is fine-but when i add a second card in the other 16x slot i get no picture.
if the second slot was bad wouldn't it still run the first card and just not detect the second?
is there a setting in the bios that i missed?
i want to run sli, but i don't want to fry my card either-ANY HELP?

sorry for the babble-its 4 am and the coffee hasn't kicked in yet.

I have a [mostly] dead slot on my board. When I put a card in there, it detects it, but won't show any picture.

So that's what it sounds like. Did something happen recently that caused this? For example, I killed mine with a botched BCLK mod.

Sounds like my AMD/nForce board (except I don't even know if SLI works on it)
Except with this one it has to be set to dual graphics cards to run a single card.

well my PSU went tits up a while ago and when i got the rma PSU back i just installed 1 card.
i just installed the second one a couple days ago.
it all worked fine before the PSU went out-sli worked at 16x/16x first and third slots.

URGH!!! looks like i might need a new MB or only run 1 card-dang!!!
