Tutorial: How to softmod to ANY VGPU you want without hardmods! (1.3~1.6v or more)

[fornowagain]

Thanks for that

Couple of things, I had to register two ocx files to get it work on Vista64, no big thing.

regsvr32 C:\Windows\SysWOW64\Comdlg32.ocx

regsvr32 C:\Windows\SysWOW64\TABCTL32.OCX

First page works fine. Second page the command line has imported the wrong device ID, should i1 not i3.
Also the Rivatuner device for the second GPU (4870x2 at least) is /sd2

You should apply changes to both GPU VRMs. CLI works with GPU selected in the main tab of RivaTuner. There is /sd<device_index> or /selectdevice<device_index> command allowing to change device selection via CLI. <device_index> is 0-based logical display device index, i.e. if there are 4 virtual display devices (2 heads representing independent displays for the primary GPU and 2 more heads for the secondary) then your should select the first (0) then the third (2) logical devices when applying the changes. In this example, command line for probing VRMs of both GPUs can look like:

RivaTuner.exe /sd0 /ri3,70,1a /sd2 /ri3,70,1a

Final line should be like this
rivatuner /sd0 /wi1,70,16,31 /wi1,70,18,44 /sd2 /wi1,70,16,31 /wi1,70,18,44

Thank you for your feedback

I know the problem about selecting the devices. The program cant dectect the device id automatically. So i have programmed it to use sd 0 and sd 1. sd 1 is used becuse thats the only id you can use when you are trying to change the voltage on GTX 295's GPU 1. As you said you need to use sd 2 if you want to change the voltage on 4870 X2's GPU 1.

Im trying to figure out how to build the application so its going to support both cards. But my problem is that this application has to be easy to use and there is a lot of combinations when you are using this mod with different cards and setups (SLi & CF). But if you have some good ideas please contribute

I can confirm this worked for me.

I have a screenshot of the final command i ran for my 4870 512mb.
Voltage bumped from stock 1.26 to 1.40.

Original voltage i game at 835/1070. After the voltage increase tried gaming at 875/1070 with 1.40 volts viewed in RivaTuner.

Even with 1.40 volts the card was unstable at the new speeds. Crashed 2 mins. of COD5 multiplayer.
