try this strap in 1:1750 and 1:2000...,slightly better than stock.I lowered tdp/tdc/mpl by 10 each(at the end,once its stable),,fan to 100% from beginning all the time, core at 1200,they dont like being lower for some reason,470's are happy at 1120..anyway..start with 1200/2000 ... do this with each card one by one... open hwinfo64 and keep and eye on GPU memory errors... if 2000mhz memory crashes or gives any memory errors, lower by 10mhz,restart.make when a card crashes dont just restart,do a full power cycle,power off,then on...work your way down from 2000. leave core alone.find each cards memory limit.use motherboards on-board iGPU for monitor(set in bios),plug monitor into motherboards hmdi.Big issue it took me way to long to figure out, if you mine with a card thats running the monitor your just asking for instability.rig is a house of cards.out of 30+ cards iv tried to run monitor and mine iv only found a couple that can mine with memory above 1750mhz and run monitor. good luck

Used your strap and suggestions.
Currently at 1200/1900 and running 27.8 (Remember I am dual mining so my numbers will be lower on ETH)
I am pretty happy with this. After I verify it is stable I will try a little undervolting.
Also none of my rigs have boards with onboard graphics.
Should I try lowering clock some?
Thanks
EDIT ** After about an hour now the speed has dropped. I still have more tuning to do...
EDIT** 2 hours later card is stable at 27.9 MH/s ETH and 363 MH/S SIA. I lowered clock to 1190.
So 1190/1900 -DCRI 13
