Does anyone have a good stable config for Keccak algo on the 280x using the multi-algo autoswitching sgminer? I keep getting at least 20% reject due to Job Not Found and a lot of stale shares as well. Never been able to figure this one out. All the other algos are working fine for me except Keccak.
Thanks!
Replace pools with the multi-algo pool settings. After that, the configuration is stable. Try it and report here. Hope it works!

I already use a multi-algo config and I'm not sure how changing the cost settings will eliminate job not found or stale shares. Please review my config and let me know what I can improve. Thsnks!

Like I said, all other algos are working fine and my hash rates are close enough to the default factors that I don't need to set it. My only problem is with keccak. If anyone else has suggestions, please chime in.
