4. I use nvidia gpu's. If I mine via dstm and ccminer in the profiles, I get errors that the rm.exe file needs reinstalling for dstm and ccminer crashes. This only happens to 1 or the rigs. Would anyone be kind enough to point me in the right direction as to how I can fix this?
Patrike answered most of your questions, but I know that DSTM needs the Visual C++ 2015 redistributable installed to work properly. Please try this and then try DSTM again.
5. Are there any tips as to how I can stabilize settings so that my current AM doesn't restart miner after a few mins? I've double checked on my rules and they're conservative enough to wait for progress and such. I'm not pushing the gpu's so much too. On one of my rigs which have the same settings, I can get 8hours straight of uninterrupted mining.
Thank you!

What is causing the restart? Is it the lack of accepted shares after 8 minutes (I think this is a default rule?) What algo is it mining when this happens? What software is running when this happens? What kind of GPUs are you using? What kind of over/underclocks are you using?
Hi puwaha! Thank you for your inputs! I've re-inputted the defaults and the restarting happens very much less than before. I can mine now for 7hours above.
I do recall doing the update on the visual c already but will do it again for good measure. Yes, that should solve it as I recall doing all that with the other rigs.
