Topic: 7850 Config @ 385~ khash for Scrypt Mining (Read 1092 times)
If you specify tc you don't need to include shaders. tc sets your shaders properly.
I'm using higher OC settings than you and still can only pull ~350 Kh 
therad-concurrency 8192 -I 20 -w 256 --gpu-engine 1100 --gpu-memclock 1350
therad-concurrency 8192 -I 20 -w 256 --gpu-engine 1100 --gpu-memclock 1350
Are an OC version? its strange, if you check this photo, my friends get more khash than me with this settings: https://i.imgur.com/CufDKdo.png
I can only go for 260
Need a better gpu...

After this, i was using this config, to get 375-380 khash using 8192 of thread concurrency:
--thread-concurrency 8192 -I 20 -w 256 --gpu-engine 1100 --gpu-memclock 1250 -g 1
Try it, and thanks for the tips of the temp commands !

I have one of those cards and can only get to about ~340/kh without affecting stability. If I set thread concurrency over 10k it crashes (and I've set MAX_ALLOC_PERCENT).
You have your temp-cutoff and -overheat reversed. -Cutoff is the temperature which CGMiner will automatically disable the card, -Overheat is the temperature at which CGMiner will automatically change GPU/Fan speeds. You want to hit -overheat before -cutoff. Also those values you are setting are very low, the default for those values are 85 for Overheat and 95 for Cutoff. I suppose those values you are setting are fine for a 2 card machine but I'd think about raising them.

Hi guys, I will give my settings for my two 7850 Sapphire Dual-X OC 
Here my bat:
Temps between 58-62, runing for 2 weeks without crashing.
Here my bat:
Code:
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o XXXXXXXXX -u xxx.1 -p xxx --shaders 1024 --intensity 20 --worksize 256 --gpu-engine 1100 --gpu-memclock 1450 --thread-concurrency 16384 --temp-target 60 --temp-cutoff 68 --temp-overheat 70
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o XXXXXXXXX -u xxx.1 -p xxx --shaders 1024 --intensity 20 --worksize 256 --gpu-engine 1100 --gpu-memclock 1450 --thread-concurrency 16384 --temp-target 60 --temp-cutoff 68 --temp-overheat 70
