I am trying to get the best out of my RX 480's I have one rig with currently rx 480's. Monday I get 6x 580 so untill AMD fixes their drivers stuff the 480's rig will get one or 2 580's too so flashing bios is not an option due to driver check. I need the latest drivers for 580 support.
The next best option seems to be watt tool but the profiles I can find are extremely limited. I actually just found one (
https://us.v-cdn.net/5021640/uploads/editor/py/ls9nfopb6mrg.jpg). But when I used this one my hash rate dropped from a stable 23.5 mh/s / 470 mh /s (I am dual mining) to 18mh/s / 260 mh's. Is anyone able to help me get the most of my RX 480's? In case it is relevant, I do have samsun memorey.
You need to look at your bios to understand how it works. There is one set of ram timings from 1750 - 1900, another from 1900 - 2000 and another post 2000.
By using the watttool profile you posted above, you are pushing your card into the territory of the memory timings for 2000+ mhz and those are the worst timings on a card.
In the profile you have, check speeds at memory speed 1749, and then at 1899. These are the two peaks that you can hit. Stay on whichever gives you maximum hash.
