This is probably a better question in a different thread but...
Anyone with 7870's and/or the nice gigabyte 280x's please share your thread concurrency (tc) and intensity? I've been trying everything it seems, just wondering if anyone found magic.

For my Asus 7870's I'm using tc 2048 and I 11 or 12, getting about 120-130 khash which feels about 50 low.

For my gigabyte 280x (rev 2, the new black one) I'm trying all kinds of the recommended tc and keep getting hw errors. 8193, 4096 mucho hw errors and few accepts.
Any ideas?

I am using for my 280X: vertminer.exe --scrypt-vert -o stratum+tcp://gpu.hashfever.com:3262 -u YOURUSERNAME -p YOURPASSWORD -d 1 -w 256 -g 2 -I 13 --thread-concurrency 8193 --gpu-memclock 1500 --gpu-engine X --gpu-powertune 0

I had to lower my clock to 1000 and it got me to about 320 kh/s.

This was posted by another user some pages back

Yeah I'm doing something wrong with my 280x... I'll keep trying. See the screenshot, I'm getting good khash but few accepts and mad hw errors right now Sad

The 7870's are doing better at the moment lol

Try to run the 280X by itself and see if you can play with the .bat file.

I had the -v and -l and took them out. The key to me to getting over 300 kh/s was lowering my clock from 1080 to 1000 and putting my mem at 1500.

Hope this helps.

try adding:
setx GPU_MAX_ALLOC_PERCENT 200
setx GPU_USE_SYNC_OBJECTS 1
COLOR 0A
vertminer --scrypt-vert -o

it will go green lol but hash better most probably pull your wu on the 280x into line and its possible mining vert with -g 2 for the 280x atleast it hates it
