I've some trouble with Zerocore on my Asus 7770 DirectCU card. With 12.4 ZeroCore doesn't work. With 12.3 it starts, but with some bugs: - It's about 5-8 minutes when the ZeroCore starts after the monitor went to standby. - When ZeroCore is "active" there is a periodically wake-up/shut down sequence. The cooler is switching off (or almost: it's slowing down) but after 1-2sec it's starting to spin. Then 1-2 sec and switches off again and starts again... and so on... So it seems to me that ZC starts, stops, starts, stops continuosly... The measured consumption is about 53-55W while in idle (with monitor on) is 44-45W. There are no running programs except few resident tasks: Speedfan, MSI Afterburner, Afterburner OSD task, Intel Rapid Storage, Audio tray icons. There are no widgets on desktop.
