I have plugged in the card as follows:







I'm getting nothing on the monitor. If i plug the card directly into the slot, it works. Any ideas?

x1 doesn't provide the same amount of power from the slot as say x4, x8 or x16.

This, do you have actual power from teh PSU pluged in too?

But even not you should have at least one in the actual slot.

i do have the power plugged into the card. What if i have one card in the slot and the rest running on 1x cable? Folding should be able to run at 1x speed. I was just testing the cable beforei started cutting the rest out. This is going to be on the MSI Big Bang X Power Mobo.

The power comes from the first few pins which are all in the x1 slot AFIAK.

Try putting the card in the actual slot in the motherboard then try adding a second card via the extender and see if both are detected in windows.

Only the one in the actual slot was detected. Tried it with a 5850 and 460 on extender. It wouldn't let me install the nvidia drivers.

Try the adjacent (black) PCIex1 slot to see if it works?
(just read post #6 that you have tried and it did not work)

Looking further ahead, perhaps using this might work:

i have seen people cut out the rest of the card while leaving the first few pins. But i have tried every way i can think of. I did find that adapter, i want to hear from people that have made it work. I don't want to order, wait and have it not work.
