XFX 7970 FX-797A-TDKC bios flash issues

Open command prompt and put it in that way.

Once open just put the values in that I listed in my post above and hit enter. You will get a confirmation message.

Yes, did that...takes commands, ran cgminer, no change...still bad.

Are you getting the poor speeds at stock clocks ? I assume that you have tried to overclock the card, especially the memory as that is what will give you the highest gains.

I also assume that you have tried ' -I 20 -g 1 --thread-concurrency 22400 ' as opposed to ' -I 13 -g 2 --thread-concurrency 8192 ' ?

stock clocks, increased clocks, etc...

' -I 20 -g 1 --thread-concurrency 22400 '  crashed me instantly.

btw...my cards just came with bios .004 where yours is .001
I tried both...no change.

Try to run -I 20 -g 1 and no shaders or Thread concurrency setting. Delete all .bin files from the cgminer folder beforehand. Assuming that it does start up then go into the cgminer folder and look at the newly created bin file the number after tc is what cgminer selected as a thread concurrency that should work.

Assuming that goes OK, then shut down and run with the new tc setting and clock your card until you achieve the desired result.

If that does not work then try the same as above but with -I 19 instead of 20.

That is the best I can suggest for you at the moment. There is a process to follow from start to finish. The help files included with cgminer describe the process pretty well. I suggest you start from the beginning and work your way up instead of possibly jumping right in the deep end with other folks already tested (on their systems) settings.

For what it is worth I have two other 7970 cards made by HIS and one of them will not go over 560 no matter what I do. Although I seriously doubt that all your cards would be limited as you say. My gut instinct would be telling me that the problem might lie in the other components that I am using in that case. I don't know if it is possible for you to do or not but have you tried to run/config the cards in another totally different system with different components ?

I couldn't get mine to do more than 650KH/s so I put away for a while. Last night I tried again and with any TC over 10240 cgminer starts with error -4 saying it couldn't load the kernel so I was going to flash the BIOS but decided to try different configs first. Now "--thread-concurrency 10240 -g2 --gpu-engine 1050 --gpu-memclock 1650 -I 13" is doing 720KH/s and I think there's room for more tweaking. That's with stock cgminer-3.7.2 so I want to try one of the updates.  Suggestions for which one and any adjustments to config?
