Cool

is it stable?
i use same card asus rx 470 4b too

I can hit 27.4 on linux.

As far I know on Windows 10 you can enable testing mode easy, the problem is AMD windows driver is checking GPU bios signature and if it is not valid id refuse to load, you need atikmdag.sys which is patched to accept modified GPU bios-es

After you use the patched atikmdag.sys, do you still need to disable the Windonws signature verification?

You can however raise the voltage given to the controller.
That controller supplies voltage for the memory

"I/O bus voltage between the memory and the GPU core. (VDDCI / AUX)"

that is correct )

seems 1900mhz is the limit for hynix ajr R0C or we have to find the way to up the mem-voltage

Well, technically you cannot raise the "memory voltage" on Polaris chips.
The only one i know off are Fiji chips and for Hawaii those Lightning models

You can however raise the voltage given to the controller.

I found the Reddit with the reference to the Polaris Editor, and references to the ATIFlash. But I have no idea what values you can touch without bricking a card.

https://github.com/caa82437/PolarisBiosEditor

That VBIOS editor is useful - too bad it doesn't expose all the goodies usable.

Anyways, my 470s don't like more than 2100Mhz (or 8400Mhz effective.)
