here´s my 580´s 90´s.
Defo every card is different, i try to keep wattage in sensible readings, like 3 last micron power colors, they need really high oc´s to go above 32mh and wattage is way too much for me then.
allso im with Ezil pool now again, with them hive reports grazy amount of invalids, the XFX on this rig got 30 invalids in less than 1hr…with other pools normally with these settings i get one every now and then, this screenshot is after miner restart to clear red from dashboard…sometimes it seems that there isn´t oc´s that work…with hiveon pool the amount of invalids is way less. Weird thing is that hive reports all these invalids, but on Ezil pool side there is hardly any, just few stale in 10min period, thats how their share graph is build…10min intervals. I have tried Ezil so many times with different setting Seems like polaris cards are the worst for their servers. These 580´s are good gpu´s and its easy to push them to -33mh, but the wattage is quite high then.
…in the mean while i have been writing this post my xfx have 4 invalids allready…
