This is going on for too long, and you risk killing your card with unnapropriate BIOSes, not to speak about the peace of mind you're losing. People posting random stuff for the sake of a bounty doesn't help either. I'm going to say this for the last time: go and post on this thread: https://litecointalk.org/index.php?topic=12369.0 Donate him your 1000 Doge and post your ORIGINAL bios.

Wait and grab your modded bios, edit the voltage to, say, 1081 mV with: http://www.techpowerup.com/forums/threads/vbe7-vbios-editor-for-radeon-hd-7000-series-cards.189089/. Or better yet, look into drakoin's undervolting/power saving thread. Donate him some doge too.

Then go to the link mentioned above, pick sgminer and those .bin files on the top comment: http://www.reddit.com/r/litecoinmining/comments/1va8g2/ann_sgminer_400_release/

Copy those bins to the sgminer folder and either use on your config:

"thread-concurrency" : "24000",
"gpu-threads" : "1",
"intensity": "20"

or

"thread-concurrency" : "8192",
"gpu-threads" : "2",
"intensity": "13"
