I got a weird values in the voltage table: Mhz | mV 300 | 800 608 | 65282 930 | 65283 and so forth. What supposed to mean the voltage values after 800?

i tried to edit them but i dont' know why not working, everytime driver will overwrite this setting dont' tell me why, this is why i use window that you can edit them without mob bios. usually you can use 900 mv until 1100 on rx 480 (on 1200 it use 1000mv) i think the same for rx 470

These aren't actual voltage values. I do not "technically" know what they mean, but these values tell the chip to automatically adjusts the voltages based on the corresponding frequencies. This is how it should be and you should actually undervolt by setting an offset either by HEX or with Wattool. You can also play around by setting fixed values (for instance 900 instead of 65282 for 900mV). Just do some google/bitcointalk search...I mean there's dozens of questions about this everywhere!

You are using the wrong version of polaris bios editor for your bios, so that straps are not decoded correctly

You are using the wrong version of polaris bios editor for your bios, so that straps are not decoded correctly Those are GPU core voltages not memory straps. There is no version of Polaris which will allow you to under-volt properly. You need to go the hex editing way.

The only thing I can find about hex editing Polaris is the memstraps. Thanks man

I can edit bios in hex and undervolt it if someone is interested.

I'd be really interested into knowing how do I undervolt under 0.95.
Both Wattool and Wattman do not allow me to go below this limit.

In PBE just change these strange numbers with voltages(in mV) and works like a charm. I have several Powercolor RX 570 Red Dragon 4GB and i modified BIOS with these values: Now the cards dig on 0.91V@1115MHz by default, and @0.887V with little undervoltage by MSI AB. Just before flash the edited BIOS, reset overclock settings and disable OC tools like MSI AB, Trixx, etc.

The reason those values are there is because voltages will be different for each card. If you notice, though, the first stepping always starts at 800. If you want your card to start with a -100mv undervolt, set it to 700 and then you can manually change the voltages later.
This helps with programs like MSI Afterburner, which only allows you to do -100mv undervolt max. If you want to go further, you have to first do it at the bios.
