Have you tried the exact same GPU/Bios combination on windows?
Maybe you are simply using a bad driver
Topic: RX470 Nitro 4GB with Samsung - Not stable (Read 399 times)
I am clueless, I bought some GPUs last time couldn't get those with samsung memory run stable (figured I was just unlucky), but now I got again 6 GPUs all with samsung memory and they crash up to 1h. Well first crashes 1 GPU, then another and so on. When I change clocks they still crashes but in other order. Hardware is for sure OK
Here are my steps (which works perfectly for hynix or elpida).
1 - Change offset in hex (all of them have built in voltage offset)
2 - Change straps in Polaris and clocks
3 - Flash it
In step number 2, with elpida or hynix I use 1325 or 1500 strap, never had an issue.
Read that with samsung 1625 or 1750 are best, however. Here are my results
Strap from 1500 - 25,5 Mhs max clocks without errors 1900, 1100 (running pretty stable)
Strap from 1625 - 26-27 Mhs NOT STABLE
Strap from 1750 - about same speed but again NOT STABLE
Strap from 1900 - 25 Mhs NOT STABLE
What am I doing wrong with samsung memory? Is there any other trick, I'd appreciate any help.
If you selling roms please contact me if you can get it running on linux with 28-29 speed (stable), I'll gladly buy it, have 3 types of GPUs. Max speed for me under ubuntu is 27,2.
