Hey slightly off topic.
Had a batch#3 running at 350 fine for a few days (110ghs). - Then the power went out. and since then It will run fine for maybe an hour before going down to 10-15ghs.
I've tried it at default settings (300) and it does the same thing. - Temps seem ok (under 75c) - Is there a reason for this? :S
disconnect the ATX Motherboard Power connector after you turn your PSU switch OFF. Reconnect your ATX PSU connector to the controller board. Switch the power on.
Also make sure you have all 5 power cables hooked up.
2 x pciE 8 pin
2 x CPU 8 pin
1 x atx mainboard power connector.
Make sure your avalon options is set to:--avalon-auto
Only other thing I can think of is you may have to reset cgminer and apply settings.
