4x 280x, 1 of my cards restarts the rig even without asm and with i 0, I can't reduce it any lower, had to revert to 11.1, no OC at all.
The same problem here. One of my 280x hangs causing multiple restarts of the watchdog! Never happened before!
I've been having same problem , at this point a clean reinstall of 15.12 seems to have my 9xR9 280x in 2 rigs at i 5 and i 4,4,6,7 getting avg 300 h/s for 2+ hrs
I could do 6/6/1/5 for a few hours, then I kept going lower to have no restarts every 2-3-4hours and in the end everything crashes, even with i 0. I know one of my cards is a bit trashed, can only go at low clock mem but it does go for years like that with an other algo or miner, so it's not like the card shat itself completely, it had a 400hour uptime with 11.1 before I switched.
Try disconnecting card by card, and cleaning pins on graphics card, also clean pins on extender cable that goes to mainboard,
with (i know it's funny, but works) simple toilet paper slice, reconnect it all back,
put intensity -i 4 , clocks 1030-1040 gpu / 1500 mem , and test again.
This miner needs a bit higher voltages than before (or lower clock - whatever you choose).
Also, on this version of miner, some "weakly connected cards" or bad extenders are showing their true nature...
as i tested, drivers have nothing with it, at least in my case(s).
15.12, 16.10.x, 16.11.x ... all works normal (some crashed, but after cleaning pcie-extenders, all gone well).

I have ordered a 4G smart router with a 8GB limitation per month, to take over when the network is unstable.
