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 ?
