Problem solved! Concurrency set to 11200. Core 975, Mem 1250, I 15, vddc 1.018. Been pulling avg 700 wu for 30 minutes stable(2 in 1 instance). Cards run cooler too. I have played with the -w flag in cgminer, but having any value (32,64,128,256) seems to hurt my hash? 350 k/hash sec is decent for a 7850 according to the wiki, but does anyone have any suggestions for getting any more power out of these cards?

I leave mine on 256... i dont think work size would make any dif

350khash for that card is pretty good. IMO if you are not getting any HW I would let it be with those setting.s

I have used the setx commands and can set concurrency at 11264 maximum. However, a concurrency of 8192 yields higher hash rates. Can anyone make sense of this? Running at 1000/1300 with I:13. Any higher intensity leaves me with a "DEAD" card in cgminer after 6-12 hours. Powertune is set at 20 and voltage is at 1.145 using trixx. I think I can squeeze a little more out of these cards and would appreciate some insight. Thanks in advance!
