Strangely, this means that the Trixx application will let me adjust the volatge on MSI Power Edition GPU core, albeit only to down volt from 1.21v where as the MSI Afterburner app does not adjust the core voltage at all, despite the fact that on the surface, it appears to work, letting you select core voltage 0.82v all the way to 1.3v. TriXX not only monitors basic parameters such as fan speed and GPU temperature but also GPU load, voltages and memory performance. This core voltage adjustment was successfully reflected in MSI Kombustor, AIDA 64, GPU-Z when running 3D. To recap what the TriXX utility is for it lets you overclock your Radeon or Fury graphics cards GPU core and memory, also it will allow you to adjust the GPU voltage, it facilitates saving. sapphire trixx i can just modify the fan and the voltage but i can not. To test Trixx, I reduced the core VDDC to 1.1v. I request bios for my GPU because it fans work on 100 RPM after maybe 3 minutes. I believe that this is due to Trixx having a VDDC limit of 1.18v.

This is how the Sapphire TriXX software version 7. Right at the start, it was displaying the adjustable core VDDC voltage as 1.21v although the slider would only let me decrease the voltage. Reading the review here on TechPowerUP and the Sapphire TriXX software section called 'Sapphire TriXX Boost' I am missing the tab Card Info and Settings also from what my internet search shows. Go to your start menu and do a search for 'regedit' without quotes. I installed the Sapphire Trixx application which as you probably know, is similar to Afterburner. If youre using an Nvidia GPU you can stop after you save, but there is an additional step if you are running an AMD GPU. The Afterburner OSD will always display what the voltage is set to on its own slider, even if sensor output still shows the actual 1.21v. +200mv (1.4V) is safe up to 60C core temp but the cards don't seem to scale beyond 150mv. +100mv (1.3V) is safe up to 85C core temp. copy\paste into the search field VDDCOffsetMax0.075 and change 0.075 to what you need. press Ctlr+F, select 'Data Type' Unicode.
Even sliding this to 1.1v or 1.3v (the maximum) has no effect on the VDDC or 1.21v. press Ctrl+Alt+SHift+H to switch to HEX view. Afterburner shows a core default VDDC of 1075mv when first installed which doesn't tally with what is actually the current 3D clock VDDC voltage of 1.21v. For some reason, Afterburner lets it appear that you are changing the VDDC voltage (once the unlock voltage options are ticked in settings). I have confirmed this using GPU-Z v0.6.4 (managed to get it to display current VDDC correctly at last) and AIDA64. THE MSI R7850 Power Edition 2GD5 card appears to have two GPU core VDDC voltage states as standard, 0.82v for 2D clocks and 1.21v for 3D clocks.

I have been doing some further testing today, using the AMD Catalyst drivers v12.8 and MSI Afterburner v2.2.3.
