I just tried to use the pci-e 1x for another 5830 in my 2x5830 rig using a 1x to 16x cable (which would make it into a 3x5830 rig).
I had partial luck...
The rig runs LinuxCoin. What happened was "aticonfig --lsa" listed all three devices, but "AMDOverdriveCtrl -h" only listed the ones plugged into 16x slots, even though it had a couple more entries in its table than usual.

When I tried to run phoenix miner on the DEVICE 2 that "aticonfig --lsa" listed, it tried to use the CPU... Angry

If anyone could help me with my particular LinuxCoin issue, that'd be great!

It's not much, but I can offer 0.5 BTC for a complete solution.

if aticonfig sees the card, I think it is initialized OK. try a different miner. I use cgminer, which would also negate your need for amdoverdirve too. cgminer will clock and fan control your cards.

Hmm thanks, I'll give that a go and post results :-)

Forgive my being naive, but how exactly would I go about doing that?

Get a piece of insulated wire, strip the ends of it. Connect exactly those two pins in the slot. Don't misconnect it or your card and/or MB can go poof.

I think what you need to do is this:
connect these 2 pins on your 1X adapter, your 2nd gpu shall be properly initialized.
