Does anyone have any input on why core clock would stick at 751 ONLY when dual mining? (it works but hash rate is 2/3 of what it should be for eth and DCR) I have running fine on another rig with different mobo and video cards. The problem board is Asus h170 Pro gaming with rx470 visionteks 4gb ram. It will hash eth just fine solo, and I had it working when I was running win 10, dual mining, however with windows 10 I could only run 4 cards. Even dropping down to four cards with simpleminer I am not able to effectively dual mine, hashes at 13-14 eth and around 400 dcr.

I have tried setting core clock to 1100 in oc tool with 1750 ram, no change. I have used both beta drivers when they were available before update, no change. I currently have pci speed in bios at gen 2, g6 enabled. Cant think of any of bios settings to try but I am totally open to any input, issue is driving me crazy. I suspect it could be a driver issue. I have try powerstate at 7 and 4. I can set core clcok less than 751, but it will not exceed that. When i mine eth solo it will adjust to my settings. My other rig functions perfectly fine, however I can not dual mine effectively with a core clock of 751.

I've been at this for days, any suggestions are very welcome.

bios settings: 4g encoding enabled, DMI/OPI Config & Peg port on auto, disabled audio, integrated gpu as default

I do have 4g encoding enabled, disabled audio, dmi opi auto, and using on board video as default. PEG is set to 2nd gen as I have issues when its on auto/gen 1 or gen 3 but I will play with it more. For now I have registered this rig under different email and solo mine eth as grouping is not implemented yet.
