btw, I'm mining with the same card
That question isn't easy to answer and has already been asked ***** times. I suggest taking some time to read this thread
https://bitcointalk.org/index.php?topic=1318921.0I pointed some option out in my post but also check the following posts.
Hey so I looked at your other post and am using nice hash but still getting 3.07 kh/s. What hash rates are you getting and what do i need to do to make it run well? I have the newest drivers and everything is updated. I have 8 gb of ram and a quad core amd processor and windows 10.
What algo, X11? You should get around 4 MH/s. Other algo will have other results. I hope you gave up mining Scrypt with your GPU.
Try the Nicehash software to check if the card works properly, do the benchmark and let me know what hashrate you get for X11 mining.
