getting 170 kh/s on my 7950 is it ok or i should get better rate?
Thats no good. Try
-I 18 -g 1 --lookup-gap 2 -w 256 --thread-concurrency 10240 --gpu-engine 809 --gpu-memclock 1250 --gpu-powertune 20,20
(use sapphire trixx to lower Vgpu to 0.875, this should get you 240kh/s and no heat)
Raise gpu-engine to 950 (and Vgpu to 0.97V with trixx) for 270kh/s (and a lot of heat).
There are more agressive settings but at the cost of very high power consumption. I guess you could get 290-300kh/s if you really need to.
(ps: all my mining cards are secondary cards, any monitor would be connected to the igp. If you connect the monitor to the mining card expect hashrate to drop 10-50kh/s and a very unresponsive desktop. Running on win7 64bit)
thank you. I could get 320 kh/s but with vertminer - stable, no HW, but very much heat
