I did that and activated all. It finally kicked in with all needed. Still dont get it how I can get higher hash rate on them.
I do wonder as the reduced settings with 2.3GH and minimal increase of heat and noise it seems to generating more value for £££ them heat the rig with higher memory MHz and try to get it to higher earning but bigger cost due to electricity useage.
I might be doing something wrong with calc.
Still got looooaaads to learn.
