On my rig with 5 x saphire rx 480 I firstly instaled newest afterburner beta 16, driver, patched all goes perfectly. After restart i started claymore my hash rate completely returned to 145 mhz.. Each card giving 29.263.. My setup for afterburner are core voltage -60, power limit 0, core clock 1150, memory clock 2000.. in claymore -cvddc 1025 Rig is working stabile for few hours so far...

But what i noticed in afterburner  is that there is big fluctating in gpu power usage it goes from 85-110w and also gpu core voltage is fluctating from 0.956 to 1.075...  This big oscilating are not good or it is normal as before on same rig i was  getting 87-90w power usage and core coltage betwen 0.981 with little oscilating to 0.987.. Didnt have device to measure real usage from wall...

How to solve this?
