Title: Settings for Radeon 6870
Post by: nuggetbram on July 28, 2014, 12:39:01 PM
The one old card in my rig doesn't seem to run nicely at all. It achieves about 350 kh/s on scrypt, but I can't get good performance out of any of the newer algos. I only get 420 on X11! I've tried all the config options I could think of...

Does anyone have any good settings for a 6870?

I've tried that, the darkcoin-mod, x13, x15, all of which with incredibly poor performance

tried with g-2 setting?  what's your current config that might be a good starting point!

Code:
--intensity 17 --gpu-engine 950 --gpu-memory 1050 --thread-concurrency 6937 --worksize 64 -g2 --lookup-gap 2 


That's what I've got at the moment, syntax might not be right as it's from memory but I know the numbers are fine
