Has anyone ever figured out how to unlock voltage on these rev. 2 cards? Really wish I could under volt them.
It is possible to flash them with modded BIOS. The question is whether they will remain stable at a lower voltage. Do you have a link to this BIOS, please? I've got 16 7970s, the only ones that aren't under volted is these 2 GB cards, plus an Asus DCII which is also voltage locked. I saved about 600w of electricity by under volting all of my cards. Takes a lot of patience and testing to find the minimum voltage they will run on 24/7 stable.

I tired every setting here my best was --thread-concurrency -w 256 -g 2 --lookup-gap 2 Core at 915 Memory at 1600, gets me 640 kh/s... How come you guys have the same card and same settings doesn't work

Even this setting isn't stable ! Do you have a single card? What happens if you lower the memory to 1500 and increase the core to 1000 or 1050? Can you paste your cgminer.conf?

I am now running at Core 866 and Memory 1500, getting 610 kh/s per card... Since Memory at 1600 led the card to crash after 1 mins. No I have 3 cards. And I don't have a cgminer.conf in the directory, I run a bat file.
-I 13 --thread-concurrency 8192 --gpu-engine 866 --gpu-memclock 1500 --auto-fan -w 256 --shaders 2048 -g 2 --lookup-gap 2

Leave shaders alone. And why do you run you mem so much higher than core? And up the -i untill the driver crashes and come back 1 level. The cards are playing chess with each-other at -i 13. Leave 13 on you card which is used for display and go up on the others. Your .bat should look like -i x,x,13 or 13,x,x depending which GPU u use for display. Spending 10 hours on the setting is not a lot. What happends if you run core=mem=1000?

I never use this pc, its made solely for mining also most people with 7970 at mining with much higher rates at -I 13.... The question is do you have/mined on a 7970?? because your post doesn't make any sense !!

The question is do you have/mined on a 7970?? because your post doesn't make any sense !! I will admit I have not. Have you tried i>13 or just read about it? On every 7xxx card I've tried it increases the hashes. Is 7970 the spoiled child of the 7 family and it only likes 13? What exactly in my post doesn't make sense?

Just to confirm: Do you have --scrypt somewhere in your command? How long do you let it run before you read the speed?
What happens if you try this one:
-I 13 --thread-concurrency 8192 --gpu-engine 1080 --gpu-memclock 1500 --auto-fan -w 256 --shaders 2048 -g 2 --lookup-gap 2
Yes, I let it run for 30-60 secs then it appears to top... Thanks for your help, I think I caught the problem which is the drivers !! Will try the new drivers tomorrow since I need to sleep.. And again thanks for helping !
