How did You solved the problem with GPU driver crashing when Megaminer shuts down miner app?
Is the solution maybe to make one dummy Afterburner profile (e.g profile5) that is CoreClock 0, MemoryClock -502, PowerLimit 70 and to load that profile 30 seconds before miner shuts down? Maybe there is some other way to change the overclock settings without need for Afterburner profile?
I don't know... All these miner/algo/pool changing apps are cool (Megaminer, Nemosminer, AwesomeMiner) but they are absolutely useless for me if the driver crashes and the rig is not mining until manual restart.
Rig restart function would be also good for this problem. (e.g I have 4 cards in rig, mining app detects only 3 then reboot).
Thank's and excuse me if there was any discussion on this topic.
I had that problem when experimenting with OC. Had it again when I got another card of the same brand and applied the sync function in AB.
The problem is very likely not related to any mining software but your OC or the cards drivers, from my experience. Did you alter the clock curve in the OC-software? Driver failure at miner shutdown usually appears when the voltage of your card drops and the lower voltage can not handle the load.
