Hello there, I followed the instructions of the op to undervolt my Gigabyte r9 390, but when I read the voltage values in the gpu freq table here is what I got :

0   0xA49D   300   Mhz   24-bit   0xA4A0   900
1   0xA4A2   525   Mhz   24-bit   0xA4A5   65282
2   0xA4A7   723   Mhz   24-bit   0xA4AA   65283
3   0xA4AC   883   Mhz   24-bit   0xA4AF   65284
4   0xA4B1   924   Mhz   24-bit   0xA4B4   65285
5   0xA4B6   960   Mhz   24-bit   0xA4B9   65286
6   0xA4BB   994   Mhz   24-bit   0xA4BE   65287
7   0xA4C0   1025   Mhz   24-bit   0xA4C3   65288

As you can see, excepting state 0, the other state voltages are not what I was waiting for.

Do you think it's safe to try values comparable to the values of the op ?

It is very safe to do. For my XFX 1015 MHz, I use the similar voltage as the OP, but is generally lower.

OP is left mine right.

1000 800
1000 825
1050 850
1050 900
1100 950
1100 975
1100 1000
1106 1050

Yup, should be good!

In the example given here, you give the DPM's a fixed state. It'll do the trick!

Just be careful though, it could be that 1.05v is not enough power to handle 1025 core clock. All depends on your gpu.
