That PSU has plenty of power for that card. Don't run Furmark was the message on this regurgitated thread and it still holds true over a year later.
Hmm, I connected the card to only one PCIe rail. Perhaps I should have used both rails (PCIe1 and PCIe2)? I thought they would be for dual gpu setup?
Nope.The temperatures both times are WAY within safe boundaries, below the 70C throttle line too. Do nVidia cards throttle when you run other Benches than Furmark? Why wouldn't my cards boost back up to where they were on the first run? Verified it with MSI Afterburner both times, I was watching it while the benches ran, both times.
Ok I am sorry to bump this topic but it really relates to my issue, I was running Unengine Heaven (the non HWBot one, which was a folly...) to compare my 670s to the dual 760 Mars RoG card that's on the front page. ( I know now they're not the same benches, but alas)
The bench was running, suddenly the screen goes black, it recovers and Windows says the Nvidia driver has stopped responding but recovered...
I ran it again, naturally, and this time the core clocks were a LOT lower, before the driver crash they were 1280 MHz max, now they're ~100 MHz less on both cards.

Nope.
The clocks are off because of the driver recovery. It doesn't usually recover fully in my experience. Reboot, problem solved.
Usually that means the card is unstable at the higher clocks.
It's just not stable at the overclock. They can't run reliably at the overclock with the given voltage. It may not have anything to do with power.Unstable? How? Neither were above the 132% max power range... or even close to it...
Bah. They're both overclocked, nothing is wrong with them. Team green, grrrrrr...
They aren't always just on or off, spend some time reading up on mosfet design.
windows rating is enough to judge your cards and will never kill your card.
You mean the Windows rating that is one of the most unreliable and vague benchmarks I've ever used?
I score a 7.4 on it.
Still can't run high res + max details
Ungine heaven.
Furmark is wayyy overkill.
