Ok so got a strange problem when mining. Mining will run for a few days perfectly fine for a number of days and then all of a sudden system will freeze up and have to power down and reboot. When rebooted will run fine again but keeps on happening. Have noticed on miner it also has crash when gets to 94% dag loaded on etherminer and then stops locks up and crashes. Cards are on default clock settings., 3 gups in rig. Someone did advise to use -L setting but each time tried to use miner just exits and closes.
Anyone with advise on how to fix.
which cards ? which powersupply ?
Possible overheating ?
