Hello everyone,
As many Sapphire RX 470 users here, Their memory types are as we all know; SAMSUNG, ELPIDA , HYNIX (maybe one more but not much).
I have several 4 GB versions of them (Sapphire RX470 4 GB Nitro+). No Backplate version
As far as i know, there are alt versions of the same VRAM type (I am talking about only Sapphire RX470 4 GB Nitro+ Only).
For example SAMSUNG VRAM:
When i save my card's bios and i open these in Polaris BIOS Editor;
As you can see, My BIOS - SAMSUNG VRAM - My SubID is E353
Here is Anoraks Orjinal BIOS ROM (not overlocked or undervolted - and it doesn't matter. It won't change SubID anyway)
ANORAKS ORGINAL BIOS - SAMSUNG VRAM - The SubID is E347
My problem starts here;I generally don't like flash CUSTOM BIOS directly. Editing your own is the best.
First, I tried to copy straps (For Samsung VRAM Copy 1750 Straps to 1900 and 2000 - thats it).
Failed to boot - I had to flash back to normal.
Then I found ANORAKS ROM (For RX 470 4 GB SAMSUNG VRAM)
But i see the SubID difference here.
I didn't know that could happen.
I couldn't flash ANORAKS ROM to my Card. When i try, Atiflash says "atiflash subsystem id mismatch".
Then i tried with these settings:
atiflash -unlockrom 0
atiflash -p 0 -f bios.romFlashed successful but failed to boot again.
I said "OK. I deal with it later. I have HYNIX VRAM too. Lets try that."
Then same thing happened again. ANORAKS SubID:
E347 My HYNIX SubID:
E353My HYNIX VRAM:
ANORAKS HYNIX VRAM:
I tried to flash it, failed again.
BTW nothing special about ANORAKS ROMs. (I tried orginals)
Then i said "Lemme try ANORAKS Powersave ROMs"
Failed again.
And i searched but i couldn't find and CUSTOM ROM for E353 SubID (both Samsung and Hynix VRAMs)
If you want to see yourself the roms, Here are the files; My ROMs and ANORAKS ROMs:

I need help because i want to mine with SimpleMining OS. But i can't undervolt them like in windows. Claymore "-mvddc -cvddc" or with OC Tunes like Trixx, etc.
Thanks
