I meant Polaris BIOS Editor - NOT WattTool.

Hmmm - but this tables in polarisbioseditor and watttol look so similar. You say that they mean different?

I think so - VDDCI would start at 950-ish, usually, for memory state 1.

Ok. Thanks for the screen and explanation.

I did a lot of tests to figure out witch voltage is wich and got only confusing results. There is clearly some synchronisation, when you change one voltage the others are often modified too.

Does someone have a clear idea how the whole thing works?

Does anybody have a stock BIOS collection for Sapphire RX470 4Gb reference models?

I ran into a rather strange problem:
- bought 5 of these cards (exact same P/N and SKU, roughly similar product numbers)
- saved the full 512Kb image of 1 card as backup (I know, I should have saved them all separately and compare the hashes...)
- flashed a modded 256Kb BIOS (I prepared this in advance, based on the image file on techpowerup)
- noticed something is very wrong with one specific card
- restored the backup BIOS image to all cards
- problem persisted, so I pulled that single card out and used the remaining 4 with my modded BIOS re-applied
- I got the card replaced under warranty (the new one has the same P/N and SKU) but I flashed it, and now it's dead (even after restoring my backup BIOS)

Yes, I know I was stupid I didn't make a unique backup of the replacement card's ROM after the first incident. It's very obvious in hindsight now...
Although, I did always check the memory type with GPU-Z and it always reported Hynix (that's why I was confident I really have identical cards).

Any suggestions?
