x1 in x16 slot - lock ups [SOLVED]

[BkkCoins]

My system has been stable for a few weeks now. 2x 5830, Ubuntu, SDK 2.4, Driver 11.6
Gigabyte GA970A-D3 board. Sempron 145.

I decided to do a few tests to see if I could move a 5830 working fine in a x1 slot to the x16 slot next to it. This was in prep for two more cards coming soon.

So now the card is on an x1 ext. in an x16 slot (whereas it was on the x1 ext in a x1 slot).

After running aticonfig to reset the X config, and rebooting, it seems both cards are detected again fine and even have the same X id 0.0 and 0.1.

But usually pretty quickly, maybe 30 seconds to 1 minute the machine locks up. I'm not even sure it's due to mining as one time I think I didn't start the miners yet.

Is this a typical indicator for the x16 slot needing presence pins shorted? Or does it ring any bells for something else maybe I missed when changing cards/slots?

I've set it back to the x1 slot it's been in for weeks now and it's running fine.
Next week I'm going to have to move things around for real.

EDIT - PROBLEM SOLVED!

Silly me for not noticing.
When I move that card it actually changes the ordering of the device numbers.
So now device 1 that used to be fine at 1000 clock is now device 0 that locks above 970 clock.
Changed my script parms around and all works fine again with x1 in x16 slot.

Funny the device numbers changed as they are still in same physical order on board. I deduce that the device numbers don't follow the physical slot order. My guess, the x16 slot has priority over the x1 slot and gets numbered first.

Once again a Happy Miner.

I found the same on my Biostar A870U3.  From right-to-left, the 16x are first, then the 1x.
