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

[Pederrs]

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

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.

i tried to register the tabctl32.ocx,and the error i get is this

the specified module could not be found.
os is xp pro sp2
any fix for this?

You can download the required file from here : http://www.ocxdump.com/download-ocx-.../download.html

after the errors, i had a look and yep it was`nt there.its all good now

With regards to the APP: Will that mean that the new voltages are set permanently, or do they disappear after reboot?

Excuse the rather pedestrian question :P

[Pederrs]

Jep if you dont have the two OCX files on your computer you can get them here:

TABCTL32.OCX

COMDLG32.OCX

With regards to the APP: Will that mean that the new voltages are set permanently, or do they disappear after reboot?

Excuse the rather pedestrian question :P

They will disapear after a restart. Im thinking of adding a feature to the program so it's going to apply your voltage settings after a reboot.

My voltages get reset after i close a 3D app.

[Unwinder]

My voltages get reset after i close a 3D app.

Are you using any software tools (RivaTuner, ATITool or ATITrayTools) managing dynamic 2D/3D clock switching instead of default PowerPlay implementation? ATI drivers have many "pleasant" specifics, resetting voltages (and fan speeds for boards with external fan controllers like 4870 X2) during re-programming PowerPlay table (i.e. during applying new clocks by any of these tools) is one of such specifics.

thanks for the app ! it works fine ... but eye already have 1.3125 volts how to get 1.4volts ?
can you just change register 18 to the hex for 1.4 volts and it work ???????

It looks like your cards "idle register" is number 18. I assume that this also is your "load register" becuse this register is holding the highest value.

So you can now move on to the next tab "Set the GPU voltage"

thanks !

Like Pederrs, our Member Maxibition from the Awardfabrik coded also a small program to make this softmod easier.

Here is a screenshot:


known supported GFX:

gtx260 65nm
gtx280
gtx295
hd4870
(hd4850) not sure, seems its not working..
hd4870x2
hd3870x2
9800gx2
and of course evry other card that uses VolterraVT11XX

If you wanna try it, feel free. Here is a download link for you
Use at your own risk!

Thanks for all the info and testing. I am going to do some testing on my gtx285. I have read it has OVP kick in around 1.26 -1.27 so I am just going to see what kind of gains I can get from 1.25 on the core clock.

[@rne]

GTX 285 is not supported at the moment..

just my luck......

ahh well...

thanks

[stummerwinter]

I get with my GTX280 by setting 1,25 V arround 1,24 V...

And good news: Maxibition works on a AUTOSTART-feature...

[benko]

for me it is working, max i can get is 1.46v(measure with multimemter) but if i set more than 1.46 volatge rivatuner will show more volatges although clock arent better.

also changed 2dmode to 0.96v also measured with multimeter and it is working+gpu is cooler

also managed to get ATT 2d/3d settings, now everything is perfect.

i am using Awardfabrik app

[tool_462]

I'm trying to use the app but I keep getting errors when detecting the I2C bus on Asus 4850's. It just comes up "invalid" for each reading.

Also, does RivaTuner not have the ability to monitor voltages on 4850's? I need to solder on a vGPU measuring point that I don't have to physically hold the multimeter in place

[benko]

probably you dont have voltera voltage regulator

[@rne]

There are some others who are facing problems with 4850. It seems that it will not work. I gotta edit that..

[10acjed]

Not working on the GTX 285 either..

tried all the apps and riva tuner as well....

[W1zzard]

there is no software voltage control for the gtx 285

[HDCHOPPER]

using awardfabrik app works flawlessly .. but after downloading it and setting my voltage , then all of the sudden my amd gpu clock tool quit locking in my settings ?? worked fine until the download of awardfabrik
this happen to anyone else ?

[Peentje]

I don't understand how some people come to the conclusion that it doesn't give them any gains on a 4870 X2. I'm running 2 Sapphire HD4870 X2 cards in CFx, watercooled (stock bios, no top bios). At stock voltage (1,26V) I was able to benchmark without artifacting @855mhz core. Just to proove that it actually does help... I left it at stock volts and upped the core frequency to 900mhz, PC rebooted as soon as benchmark started, I did this twice. I changed the voltage to 1,35V (seems to be the max possible with this vmod according to people here using a DMM, I will check this myself later on) and put the frequency at 900mhz again. No crash, it ran the benchmark smoothly. It does help. Do keep in mind that I'm watercooling my cards, maybe that helps a bit extra.

So this post is just to confirm what others have saying.
