Same problem for me too.

I have 3 cards, the 2 of them has bios ver.015.041 and other has ver.015.039

The 015.039 card running at ~740 (72c temp) and its very stable. Even at higher temperature its ok!
Also I undervoltage the card at 1.137 volt with Trixx and gain -5c on temperature without lose speed.

For the other two cards, on windows, I never passed 700 with many different settings.
Now I am using linux (SMOS distro) to run those two cards (015.041) and getting ~710 only if temperature stay lower than 70c.

You have right about the bios. I followed the same steps you did, and after searching came here.
I cant downgrade BIOS, or i didnt find a proper rom yet that fits.

Here is my config and hope someone find a better solution in the future.

Code:

{
"pools" : [
{
"url" : "x",
"user" : "x",
"pass" : "x"
}
],
"api-listen" : true,
"api-allow" : "W:127.0.0.1,192.168.0/24",
"intensity" : "20",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"auto-fan" : true,
"temp-cutoff" : "85",
"temp-overheat" : "80",
"temp-target" : "71",
"expiry" : "30",
"gpu-dyninterval" : "7",
"log" : "5",
"queue" : "1",
"retry-pause" : "5",
"scan-time" : "30",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"shaders" : "2048",
"thread-concurrency" : "24768",
"gpu-threads" : "1",
"gpu-engine" : "1080",
"gpu-vddc": "1.130",
"sharethreads" : "32",
"lookup-gap" : "2",
"gpu-powertune" : "-20",
"gpu-memclock" : "1500",
"no-submit-stale": true
}

Interesting, so what are you VRM temps like?

I noticed that my fans by default were spinning quite slow around 45% so I upped the fans to 70% and that got the VRM temps back to like 85 degrees C.
