I just got my two Antminer U2 and followed
this guide to set them up, but ran into a problem:
Wether i use a batchfile or start bfgminer manually without options and setup in the program bfgminer's window will disappear after a short while of mining. The process though remains active as i can see via the taskmanager.
What culd be causing this?
Details: Win 7 64 bit, BFGMiner 3.10.0 64 bit, mining on eu-stratum.btcguild.com. The two AMU's are connected directl to the PC via the onboard USB slots using lengthening cables. So far i only ran with default clock (x0781) via batch (since you cannot set the clock in bfgminer itself I suspect it uses that setting aswell when I just start BFGMiner and setup the devices in the manager).
could underclocking be the key?
