r9 win 8.1 v0.22 , 1060 lubuntu 17 v0.22, 1050 ubuntu 16 v0.22

Confirmed, conf 2x1060 3gb , crashes randomly on Windows 7 x64, teamviewer bug exist -------

same conf , no changes 2x1060 3gb, runs on Lubuntu 17.10.1 no crash 6+++++ hours , no tw bug. +++++++
Hash rate 1060 3gb on optiminer-mnx  6700sol/s , on lolminer-mnx 10600sol/s


Today i will install on 2x1050 mashine to check out , current on 2x1050 windows 7 give me on lolminer 5300sol/s but unstable

This is my bat file. Not the best solution but works on unstable mashine, use smaller timeout to get more stable or longer if the mashine is more stabled(less hangs,crashs)

hope this helps.

For your Nvidia I recommend not to change work batch from default and use 2 cards in one instance without alternative mine thread. That should give least CPU load and best performance unless you have the "TeamViewer" bug.

Enabling multigpu Without options gives me much better hash rate
conf 2x1060 3gb (non TI) , 19600 sol/s ( about 9800 per card ) but crash randomly. Hope for 0.3v to solve issues.

Very good job.

Solution is simple

Windows Task Scheduler

every hour taskkill /IM guiminer.exe /F

then In Task Scheduler make task not simple task to start guiminer

guiminer.exe

start in : directory of guiminer
