Can anyone with a similar rig comment on stability? How often do you need physical access to your rig, and why?
I'm hobby miner. GPUs, Block Erupters, BlueFurys, Bitmine U1s and DualMiners. Thanks to LightningAsics sloooowwwwnes and nonresponsiviness I'm still waiting for 5-chip Gridseeds. I can only say that DualMiners are the reason installing CGWatcher for the first time. CGWatcher successfully replaces Dualminer GUI mining program that is not being capable to successfull restart miners. Because they need restarts too often to be manually restarted. I'm mining with Win7 x64 in scrypt-only mode, power supply is not the problem and from time to time some of them knows to disappear from list of COM ports under device manager. The only way to bring them back from nirvana is to disconnect/reconnect at USB hub. To summarize, they are worst units from my collection for unattended mining. Maybe next version of BFGminer is going to make them more reliable.
