I was able to get my XFX GTS RX 580 8GB to 31 Mh/s!!!!!
31 with Hynix, is that stable? Any memory errors?
I just figured this out like 4 hours ago. I ran it at 31 for about 30min and didn't get an error. I ran it at 30 for an hour and didn't get any errors. Right now I'm dual mining Eth and Sia at 28Mh/s and 830Mh/s respectively. This has been running for the last 2 hours and it hasn't had any issues.
Edit: Forgot to add. These cards have 4GB of Hynix and 4GB of Samsung memory. Hence why so many people have had issues overclocking the memory on them.
I just found some Gigabyte RX 570s at my local Frys, so I'm going to try those out and won't be able to test the stability of the XFX today.
Used Your help with timmings in my XFX 580, and got 25.7-25.9 ETH & -+ 770 SIA in dualmining, wthout touching clocks and voltages in system (win7).
Unfortunatly any change in Afterburner coses fuckylion memo err and finally crash...pow cons doesnt decrese also... ASIC 73,7...
any idea? ;-)
thx
