Can someone tell me why one of my cards on my 11 card rig is getting incorrect shares?
I've tried lowering the cc 1115 and mc to 1875,m but that doesn't do anything really.
I was thinking maybe it was the driver.
My other 5 rigs are 6 card rigs, with the blockchain driver. cc at 1125 and mc at 1950....all those rig don't have any incorrect shares.
Thoughts?

i have never had good results going above 1100
otherwise maybe try raising voltages in +5mV increments
some of my older gpu need a lil more juice than auto sets them at
i should add i have all my gpu set to about 1075 core and +200 mem
unless the mem starts at 1650 then i do +250
and i get the same hashrate per gpu as u
also if mem starts at 2000 i usually drop it to 1980
but this could prolly be fixed by copying a higher strap than 1500
Original clocks ar CC 1281 and MC 1750.

It also may be incapable of higher memory clocks. One of my cards refuses to go higher than 1800mhz on the memory clock without generating excessive errors. Silicon lottery...
I'm gonna try what @cidmo said. I'll put the core at 1072 and memory at 1875...if I try to put it at 1925 it gets unstable and resets to default settings.
...these 570s are a pain in the ass, wish they still made 470s.
Default memclock not changed in ROM. Try to step up until you find max stable.
GPUclock set to 1150. Don't see a reason to set another.
My MSI 580 Gaming X with Elpida 4 GB capable to run 2025-2075 memclocks.
Maybe yours will run the same after this mod.
Update: "mod2" is the same thing as "mod" but with increased power limit from 120 to 145 W. Maybe it also matters.
CC at 1125, and MC at 1875....I tried to set to 1900 but it gets very unstable and hashrate drops to 20, 1950 crashes it.
Also, the power draw is at a nice 62watts...but only when it's the only card mining. When I turn all the cards on, it goes back up to 85watts.
