Ok cool. Try adding the modified command below...password was before the worker name that may cause a problem not sure, you shouldn't need  "stratum+tcp://" from memory and added 'mode 1', ETHASH only, assuming you're not dual mining.

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100
start EthDcrMiner64.exe -epool us.ubiqpool.io:8008 -ewal MYWALLETADDRESS -eworker rig1 -epsw x -mode 1

Is that literally your batch file? because the MYWALLETADDRESS value should be replaced by your Ubiq address. (Hopefully I'm not stating the obvious but just in case)

Do you have a monitor attached to GPU2? You'll generally see lower hash rates on GPUs with monitors attached (or using team-viewer etc). If you leave it a while to idle you'll probably see it pick up pace.

I really do feel for all that had BTC locked up in NiceHash, hopefully if it's not an exit scam they make it right.

It is interesting to see what a difference having NiceHash offline does to the difficult on some coins. Some have/had dropped by 40% or more in difficulty.

I'm glad someone is breathing life into this, it seemed like it had a lot of promise last time around.

Maybe second time around it'll flourish.
