5850 settings

[talldude]

Best settings for 5850 on win7, SDK 2.4 are:

phoenix miner, -k phatk VECTORS BFI_INT AGGRESSION=13 FASTLOOP=false WORKSIZE=256

it nets me 340mhash with 850 core. About 10mhash more than any other setup I've tried.

Give it a try.

Yep this is one of best flags for most 58xx miners.
Aggression may vary though and this high will usually make your computer less responsive.

I've actually been experimenting with worksize=212 (and other numbers like 200 or 192) and it seems to be a little faster (1-2 Mhash/s) for some reason..

Has anyone got multiple 5850s working in windows with phoenix ?

I'm getting this error when I try to start another card :

FATAL Kernel error: Failed to load OpenCL kernel!

I'm stupidly running a 5830 and a 5850 on a single core cpu, so I use AGGRESSION=8 for the first card (hooked up to the monitor), and 10 for the 5850.  Then my CPU load is really low.  Too much higher on the aggression, and the cpu load climbs very fast, and it will crash at some point (probably when I'm asleep )
