It's all about timings... those basic copies straps aren't fastest.
Any ideas on how timings could be improved for Elpida memory?
I've got 14 of those Asus RX 570 Expedition OC's. They're all featuring Elpida mem... So far I've only copied the 1500 straps upwards and played a little with the clocks. Wonder if there's any more room.
I have good Elpida timings 29MH/s. PM me.
I have 2 x AMD Radeon RX580 Gaming 8GB with samsung memory.
from box ethereum hashrate was 24.5 mh/s than I change timings with Polaris Bios editor. I copy from 0:1500 to 0:1625 > 0:1750 >0:2000. after this I get 29.8 ~ 30 but after 2 minuts go down to 20, 14, 10, 7 till 4.1
Then I returned everything back and copy from 0:1625 to 0:1750 >0:2000 and I get stable 27.8 ~ 28.1 power consumption 130 watt
per card. can any help me with proper timings to get stable 30 mh/s
thi is original BIOS image

Did you check for memory errors? Overheating? Use Uber-mix 3.1 or 3.2. Or PM me.
