Thanks for the help. I will try with 24 E6 XX. I don't have any thing to sniff I2C, but I can get I2C values with aida64: [ ATI I2C Device GPU #1 / B06-D24 ] 0000 FF 80 17 7F FF FF FF FF FF FF FF FF FF FF FF FF ............... 0010 00 FF FF FF FF FF FF FF FF B0 FF FF FF FF FF FF ................ 0020 22 00 FF FF 00 18 A8 FF FF FF FF FF FF FF FF FF "............... 0030 FF FF FF FF FF FF FF FF 01 00 FF FF FF FF FF FF ................ 0040 FF FF FF FF FF FF FF FF FF FF 64 FF FF FF FF 55 ..........d....U 0050 FF 46 00 64 FF 10 FF FF FF FF FF FF FF FF FF FF .F.d............ 0060 FF FF FF FF FF FF FF FF 2C FF FF FF FF FF FF FF ........,....... 0070 FF FF FF FF FF FF FF FF 00 00 00 00 00 00 FF FF ................ 0080 FF FF FF FF FF FF FF FF E9 FF FF 3F F0 00 FF FF ...........?.... 0090 FF FF FF FF FF FF 64 FF FF 1A 22 03 FF FF FF FF ......d..."..... 00A0 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF ................ 00B0 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF ................ 00C0 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF ................ 00D0 00 01 00 03 50 02 00 FF FF FF 01 FF FF FF FF FF ....P........... 00E0 FF 00 00 02 03 03 00 3D FF FF FF FF FF FF FF FF .......=........ 00F0 FF FF FF 68 FF FF FF 0A BC 9C FF 07 FF 0F FF FF ...h............

It seems that these values aren't related to i2c bus or i2c addredd: Hawaii Bios Editing ( 290 / 290X / 295X2 / 390 / 390X ) - Page 316 Edited: I have tested with 05 03 12 00 10 08 24 00 01 00 00 00 E6 00 02 00 FF 00 And it is not working, I have tested with 10 to the ID because I see here: Linux/drivers/gpu/drm/radeon/atombios.h - Linux Cross Reference - Free Electrons ,that VOLTAGE_CONTROL_ID_NCP81022 is 0x10. I will test to 05 03 0C 00 24 E6 02 00 01 00 00 00 Edited: I have tested with 05 03 12 00 10 96 48 00 (01&00) 00 00 00 E6 00 02 00 FF 00 and it isn't working I have tested 48 because I2C address is 24 = 0010 0100 --> 0100 1000 = 48, you know. And 96 because it's used on every controller.

Yes I know it, thanks. Do you know how to add these registers in VoltageObjectInfo table?. I think that it can be done by adding some thing like that: 52 00 03 01 01 07 0C 00 0E 00 00 00 00 00 00 00 04 00 24 00 00 04 00 00 00 80 10 00 00 00 00 00 39 03 00 80 00 00 9D 03 00 00 10 00 B6 03 00 80 10 00 1A 04 05 03 12 00 08 96 60 00 00 00 00 00 E6 00 XX 00 FF 00 05 07 0C 00 0E 00 00 00 00 00 00 00 For voltage offset, E6 + XX voltage offset. But I have tested it and it isn't working. Maybe because the 08 96 60 values are wrong. I have a 380 saphire nitro with a 81022 controller, and I think that these values 08 96 60 are only for Asus controller: https://www.techpowerup.com/reviews/ASUS/R9_380X_Strix/4.html , https://www.techpowerup.com/vgabios/177957/asus-r9380x-4096-151104. or ir3565b. Any ideas?

Hi, I have a 380 and I know that Address 20 (my addres is 24) Register E6 Data 10 is an voltage offset of +100mv acording to this: https://forums.overclockers.co.uk/showpost.php?p=28012664&postcount=41. In NCP81022 datasheet: http://forum.hwbot.org/showthread.php?t=157437 , Register E6 is named as Special purpose offset. I have tested register E6 via Afterburner and it's working. I have tested register 21 via Afterburner and it isn't working. Register D2 to 1 give my a blue screen via Afterburner. I think that the only way to do to work register 21 is adding it to the VBIOS via a VoltageObjectInfo mod. I was trying to add register E6 to VoltageObjectInfo: Hawaii Bios Editing ( 290 / 290X / 295X2 / 390 / 390X ) - Page 316 , but some values are missing, any idea?. Thanks.
