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
