Overheating is out of the question. The Internet connection might be the problem as I'm back in my home town for a few weeks and I have a weird connection here.
I tried using both dedicated ports for X11 and X13 on TMB, but then I tried to switch to Scrypt as well since Razercoin became more profitable some days ago. What I did was to include the 3330 port together with the 4010 and 4011 ports and that's when I started to notice the miner idles after some time. Then you released the TMB Switcher software and wanted to try it, but I still got that random idling (miner stops and waits for work from pool). So I tried 4010/4011 + 3330 and 5550/4440 + 3330 and it makes no difference when it comes to this idling. I haven't been able to figure out what triggers it yet, as I managed to catch it one time after 20 minutes and another time after 1 hour, yet another time after 7 hours. The Internet connection might be responsible for the 20 mins idling, however I doubt that those 1h+ idlings are triggered by the connection, as I haven't notice any connection dropout longer than 30 mins.
Please do NOT use the 4010/4011 ports with this switcher. This switcher will handle all of the switching for you so if you use the 4010/4011 ports it will not work properly.
Is there a way to get this to work with the sgminer variants that use the global -k argument (and have to be restarted in order to change kernal)?
Ideally, I'd just point to a bat file for x11, a different one for x13, and another for scrypt, etc...
Any hope of getting this to work with ccminer for us nvidia folks?
Doing things this way is possible (that's how the last switcher I used worked) so I may at some point update it to allow this type of algorithm switching. It wouldn't be something I could change immediately however I would like to make it work with nvidia cards as well at some point.
