I fixed my issue by fixing my PC's time. Apparently it was off by 30 seconds or so.
Ahh, that makes sense. OK will try syncing to NIST time servers or something. Thanks.

It would be risky adding a 380 to a PC that already has a 290X on a 550W power supply.
For reference I have one 380 + one 390 on a FX 8350 platform with half cores disabled and underclocked etc powered by a Seasonic 750W. With this combo I undervolted / power tuned both cards pretty severely and it's still pulling 440W from the wall. You could probably get away with it with careful tuning but not at stock voltages.
I've had my finger hovering over the button on a 4GB 380 so I've got a power meter to see how much I'll be pushing the PSU. Power draw from the wall at stock clocks is 300W, taking into account the PSU efficiency that puts the system draw somewhere in the 260W range. The CPU is undervolted and doesn't break 60W under gaming load, <20W idle. By a fairly conservative estimate that gives me 200W to play with before I exceed 500W system draw. That fits neatly with the power consumption of the 380 according to what I've researched although a lot of reviews are more concerned with OCing it to the max and making it suffer rather than being nice and underclocking it a little......think I'll take the chance and grab the 380. I predict 500W max from the wall which would be 450W system draw even at 90% PSU efficiency, I'm perfectly comfortable with that on a 550W unit and there's still room to underclock the cards further.
I'm probably still going to buy a little ether but the nice thing about mining is even if the whole thing collapses you're still left with a gpu to sell to get something back.
Im running a 280x and a 290x in parallel on a z97-i plus. The 280x is actually running through the mini pcie-slot usually used by the wlan module.. so far flawlessly.
afaik ethminer will use all gpus automatically and post them on startup, but you can also manually define their number with "-t X" (X as number of gpus)

It looks like both Suprnova and Nanopool are down right now.
not sure about supernova but nanopool is working fine for me.
They are back up this morning but both were choking last night. Getting 503s on Nanopool and suprnova's page wouldn't load. My miner couldn't connect to either of them either.
I'm having a problem trying to underclock my 290 (Sapphire Tri-X). Normally I use the AMD Overdrive panel and while it will overclock the card no problem it simply doesn't have any effect if I underclock (as in I can change the slider but the core clock stays stuck stubbornly at 1000mhz). Tried MSI Afterburner with the same result, is there some setting I have to change or something obvious I'm missing here?
Especially strange since I just got my 380 installed and Overdrive can underclock it no problem. It's mining away happily at 63C while the 290 is getting uncomfortable at 82C, just want to drop the temperatures a little. Seeing 45MH/s between the two and 460W power consumption from the wall.

Sorry if this has already been asked, but:
how much longer will people be able to mine ether? Is there a cutoff date? Some earlier posts in this thread made it seem so.
Interesting. So it isn't a set cutoff date.
Anyone tried doing this with an R9 285 yet?
