Has anyone got more then 207kh/s out of a 5770?
I can't get more than ~145 kh/s out of mine. I am currently running it in a box with a 6870. The 6870 is getting ~300 kh/s. I start CGMiner with the following command.
Code:
$ ./cgminer --scrypt -o http://litecoinpool.org:9332 -u XXX -p XXX -g 1 --thread-concurrency 7840,8000 -I 20,16
This is with the default clocks. I did try a little overclocking but it still would not go over ~147 kh/s. I am running Kubuntu on this box.
Those are low numbers. My 6850 can pull 262 kh/s at intensity 17, and my 5770 can pull 207 kh/s at intensity 18.
First gpu is 6850, 2nd is 5770:
Code:
--worksize 128,256 --gpu-engine 900,885 --gpu-memclock 500,1235 --shaders 960,800 -g 1 --intensity 13,17
Yes both my cards have a core overclock, 5770 likes small overclocks, but 50mhz+ on both core and memory drops hashrate (?).
And yes on my 6850 I am downclocking the memory to 500, it doesn't change my hashrate. AT ALL.
