Title: what are good command line flags for sapphire 6950
Post by: ehmdjii on June 20, 2011, 09:24:35 PM
hello,
just got my sapphire 6950 and default mining is running at 310Mh/s

i ve read that using several command line flags to start the miner can improve this. which ones are recommended?

edit: catalyst 6.11 / win7 64bit / guiminer

pocblm is default for windows machines I believe.  With OC and -v -w128 I'm achieving 400m/hash

yep, also -f60 if you going to attempt to use the machine while mining. Increases responsiveness.

After that, you can always OC that pos and extract some neat MHash/s more.
