Okay, thanks. I usually do have three or four different start.bats for those very reasons. Dual setups, Eth only different pools etc... One thing I had happen recently that got me thinking along these lines was one of my rigs had a gpu hang and I noticed when the miner restarted I lost fan control on that particular gpu. It got me wondering if that had been setup in config instead of start.bat if it would have made any difference?
