Edit: I got it, thank you for the tip!

Take for example 1750Mhz, it's 98AB0200 -> 98 AB 02 00 -> this part is important: 98 AB 02 -> reverse it: 02 AB 98 -> now convert it from base16 to base10 and you will get: 175000. Looks like 1750 Mhz to me

If you want to take 1975 and convert it to hex, you need to it make base10 to base16 conversion (197500 -> 03 03 7C) -> reverse it: 7C 03 03 and voila, ready to paste into the bios.



The best way to do it is to add negative voltage offset.

What card model are we talking about? It will be easier for me to answer if you post your specific card model or even factory bios. Isn't that Nitro+ by any chance?

I might pick up a Nitro+ 4GB RX470

Posting here so I can get back to this in my post history

Can you link to that article, please?

Yeah, that topic is awesome and very rich, but it's huge.
Do you have any knowledge about how to add a voltage offset that you can share directly here?
Mny of use would appreciate it

Thank you for those info. It's the best explanation i've received!
Since the effort is so big I think that change it in WattMan is more effective for my home setup.

So I was playing with Polaris BIOS editor, trying to adjust some stuff in custom BIOS for my 480s 8GB Ref.

What I figured out is that while all the other values I change (Core clock, MEM clock etc...), after flashing OS is using that values, but whatever I enter in GPU voltage, it looks like OS is overriding those values...

For example changing voltage from 850mV to 1100mV has no effect on power consumption from the wall, which is strange...

Why are those values ignored?

I am using ethOS, and ubuntu OS

Thanks in advance
