Figured it out in the end. Was just a driver issue. All back up to speed now Thanks.
Thanks.

I have started having a weird but similar issue.
I have been happily mining for months with 3*7950s using the below bat file:
cgminer --scrypt -o stratum+tcp://eu.wemineltc.com:3333 -u username -p x -I 19 -g 1 --thread-concurrency 22400
For some reason my GPU0 has decided to run at a much lower hasrate. The other cards hash at around 550 and GPU0 can only manage 80-100.
https://i.imgur.com/ztC6bd6.png
As I am sure you can see from the above I have intensity set low but even when it is at 19 it only manages 100-120. I checked the clock settings and CGMiner seems to think the GPU clock is a 500 and the Memory clock is at 120!! I tried overwriting these in cgminer but to no avail.
CCC seems to conclude what CGminer does about the clock speeds. (although I have found in previous experience these would normally increase as soon as there is any load on the card)
Any ideas anyone?
Sounds like you switched pools or edited something that should not have been changed. Delete your .bin file(s) in CGMiner directory. Reboot. Start CGMiner, wala, magick. I have been happily mining for months with 3*7950s using the below bat file:

That's good news - what hash rate are you getting now?
With adequate cooling, 715KH/s on the outside card.
The inside card is currently not on a riser, and doesn't have room to ventilate due to the card on the outer most 16x PCI-E slot. So I have it at -I 12 whilst the outer card is at -I 20. Both run flawlessly with out a single HW error. Thanks again for the tips everyone. Once I have all four cards mounted with risers/powered risers for both 16x, I will have each card running at 715KH/s+ for a total hashing power of 2,860KH/s. No, my cards are not 7970s!
They are 7950s. I have no idea why I'm able to achieve such an amazing hash rate. The only thing I can think would be the fact that I am using 12.8 AMD drivers and 2.7 SDK drivers.

Final stats that worked are as follows:
Delete all .bin files associated with preferred version of CGMiner. I chose 3.1.1 due to recommendation and most up to date version.
Clear CGMiner .bat file.
add
cgminer --scrypt -o http://yourpooladdresshere.com:PORT# -u Miner.X -p XXX -I 7
Results were a new .bin file. The number after TC was 22400.
New .bat file.
add
cgminer --scrypt -o http://yourpooladdresshere.com:PORT# -u Miner.X -p XXX -I 13 -g 1 --thread-concurrency 22400
Results were an accepted connection, and correct hash rates in relation to O/C and -I XX command in .bat file.
Thank you for everyone's help. I'm sure this thread will help many more prospectors.

I'm not all-pro like as some folks are around here but my 2 cents: you have gpu threads set to 2, so you can not use a thread concurrency of 20k or so.
You can either have a gpu thread of 2 and use a low thread concurrency of somewhere between 7500 - 9000 for your card, or a gpu thread of 1 and have a thread concurrency of 20000 - 24000 (mine is set to 21712) .
Also, did you know that for scrypt, the intensity settings are all different than sha-256 ? You may want to try an intensity of 19. High intensity for scrypt is 14-20

Do as above, and delete all your bin files (created when you launch your miner will have a long file name)
remove the TC from your settings And also remove shaders. start your miner, and see what number throws up after tc in the file name.
thats a good place to start for thread concurrency.
i got 3x 7950 running 715h/s @ about 75-81degrees C pulling 900w
thread concurrency is in the 20,000's intensity 13
[edit]
sorry am running 7970
tc 16384, mem 1500, i 13

Try typing in command prompt and see if it works without the extra settings.
Code:
cgminer -o http://binarycoins.eu:9333/ -u p -p 1 -I 7

Suggestions please.
I can't get these cards to act right!

Cgminer let me set the TC to 25088 before I started giving mem value too high for cgminer. Had to drop it back to 7168. When I changed the value my kh/s went unaffected. Am I missing a command somewhere? Is --aggression the same as intensity? Any other commands I should try? This is mind boggling since I've ran them @600khs each no problem. I was a retard and didn't save my .bat compilation before formatting. Should I try different drivers? Different version of cgminer?
May 20, 2013, 11:37:43 AM
I think its meant to be a multiple of your shader value, but I've just set mine all to 22000 and it seems to work okay. I seem to remember getting lots of HWs when I set the TC too low. Hope you get it sorted
May 20, 2013, 11:04:04 AM
Thread concurrency should be more like 20000. Also, is that your username and password publicly visible?
20000? I thought thread C should be multiples of your shader value? Used generic info for login info, not my personal
. Thanks for the friendly reminder though. May 20, 2013, 10:53:00 AM
