Title: Having issues with my Radeon 5850 Post by: declensions on July 20, 2012, 05:31:53 PM Hey guys, I'm totally new to this.
I'm wanted to try this for fun and installed GUI miner. However, I found that my radeon 5850 only produces 150 mhash/s or less. Any idea how to fix this? Any useful guides for a first-timer?

are you using OpenCL miner? Title: Re: Having issues with my Radeon 5850 Post by: bitminer9 on July 20, 2012, 11:49:36 PM It sounds like you haven't added the flags as Rlx160 pointed out. You can also use the "-f#" (ex: -f1) to indicate how much GPU power will be used. The default is 30.

btw, removing the flag doesn't do anything after adding it, how does this work? Do I have to press enter everytime i type something in the gui? is radeon 5830/5850 still the best bang for the buck? Title: Re: Having issues with my Radeon 5850 Post by: anddy78 on July 21, 2012, 01:22:38 AM You can reach close to 390Mhash/s with that card...

Downclock the GPU memory to 300 or lessQuote is radeon 5830/5850 still the best bang for the buck? Popular mining cards :https://en.bitcoin.it/wiki/Mining_hardware_comparison#Popular_Mining_Cards Look at MH/$ and MH/J. The higher, the better.
