I tried almost everything I can't OC past 1415~1430 Mhz I'll get artifacts in heaven bench I'm running at 1430/2125 and 1200 on core volts , Temps reach around 65c max on Heaven Power limit is also set to +50% HALP !
Either increase volts or reduce temps drastically by going water cooling. There is no magical fix for hardware reaching its limits(artifacts)
You can only go so far with software overclocking.. The cards bios has clk setting for the ddr also they dont run the ddr at max volts according to jdec. Bios has a lot more option. If you want to become extreme oc you gonna need to learn to do cooling, solder & bios mod
not worth it between the buggy drivers & Polaris was doomed because it was a rebadge die srink of r9 failure not enough core count bad power draw midrange card over msrp. not much of improvement from 1050ti. unless your trying to compete for number 1 on the list. i would just buy a used 1080 1070 or ti
I got it figured out . I'm using AfterBurner , 93+ volts , 1450/2200 and stable on Unigine Heaven and Furmark Thanks for your advices guys
