Fiji Bios Editing ( Fury / Fury X / Nano / Radeon Pro Duo ) - Page 127

post #1261 of 1773
Use Fiji Bios Editior - then read the guides posted and teh corresponding voltage table supplied - pick a voltage you want and chuck it into the final power state e.g. 1137 = 1.137v before vdroop.

Ok so in the picture attached i have to set -125 to the colum VID e.g instead of 900 -->775 an so on... is this correct that save and flash

You need to know what the stock vid is for each dpm. Do a bios dump through aida64 to learn what they are. Every card is different. Then you can subtract 125mv from each and input the number. To make it easier on yourself, only touch dpm7 as long as it is above dpm6 after subtracting 125mv.

I highly suggest for you to read through the whole thread as there is a ton of info to learn. Those values in your picture for dpm2-7 are for the AMD powerplay feature and not representative of actual voltage.

Adjusting DPM2 is problematic due to voltage droop. adjust it very little or not at all. For me DPM2 is actually slightly higher than stock VID. It just worked better for me. If you are adjusting voltage per DPM, the greatest adjustment is @ DPM7 and use reducing adjustment values to each lower DPM 6-3.

Can u help me please with an example of adjusting on this image http://imgur.com/0FwbcZg so i can go with -125mv.

Thx in advance

Sorry for delay, I've set 105°C for VR_VDDC (same ref PCB Fury/X), the mosfets are the same on Nano as ref PCB Fury/X, just less phases.

I really can't say if safe or not to use ROMs with this temp throttle threshold so your choice.

These ROMs are the Nano 107 ROM with VDDC offset as +/- 0mV and HBM offset set to achieve voltage as in title of ROM plus VR_VDDC 105°C throttle temp instead of 98°C , VR_hot is stock 127°C and OTP 134°C in IR3567B.

HBM voltage offset data value is located at 0xACE6.

VR_VDDC temp threshold data value is located at 0xA36D.

Interesting. So I flashed the bios but the Nano wouldn't get passed the Windows login screen - no harm done as I simply switched to the other bios and flashed back but there does appear to be something else going on preventing it from operating correctly - maybe a protection mechanism wrongly kicking in?
