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

[mattkosem]

I asked this earlier but no one answered.
Were people doing the previous soldering resistor hardware mod also seeing issues with firefly forest in 3dmark not being happy with higher GPU speed (past what you could do at stock voltage) regardless of the hardware changed volts?

I was able to run with 890mhz on both cores when I had the hardmod installed on this card and set to 1.41v. The card was hot enough that I had to turn down my cpu clock to maintain stability. I've not seen either effect with this soft mod.

to complicated for to change the voltage on my gtx260-216 any easyer ways please help ???

[fornowagain]

correct command for checking VRM status is /ri<bus>,70,d

Many thanks. Comes back with 0xd8 (216), any significance to that?

Hmmm... That's a status of 100% healthy VT1165 VRM. The status bits include:

- VRM reports that its voltage output is enabled (VRM can be shut down due to fault condition on some of slave phase chips, e..g. due to critical overheating)
- VRM reports that output voltage is in "power good" state (i.e. the difference between nominal and real output voltage is inside pre-defined "power good" range, e.g. 100mV)
- VRM reports that there are no input undervoltage and overvoltage conditions
- VRM reports that thera are no output overcurrent and overvoltage protection conditions

According to these state bits, there is desired voltage on the VRM output. Looks like there is some other circuit on your PCB limiting the voltage behind VRM output.

yepp i did it(i hope so) in riva tuner i got new voltages but havent tested yet.

here is pic, how can i fix this that gpu dont change voltage every second(it went from 2d voltages to 3d voltages every second) i have chanhged both 2d and 3d voltage card has also before doing this chnged this voltges every secon(before was 1.2-1.26v)




how can i get it in 2d that it is always 1.1v??

anybody can help here??

That's by design of AMD 4800 series PowerPlay controller to change clocks and voltages depending on GPU load. And AMD were "smart" enough to make GPU load sensor sensitive to most of 2D acceleration in addition to 3D acceleration, so any window (e.g. browser) scrolling is seen by PowerPlay controller as GPU usage requiring clock and voltage boost. Close all windows (including dynamically scrolling hardware monitoring window) and GPU will stay undervolted.

lol what an idiots!!
does this bad for voltage tuner??

can i somehow change sensitivity?

thx for reply

You can use ATI tray tool and create a 2D and 3D profile. ATI tray tool only set the 3D profile when detecting Direct3D or OpenGL application are launching. You can even specify applications that should not require the 3D profile to be triggered.

I've set 2D clocks at 250/250 and 3D at 800/1000 it and it works great. But in my case, the voltage is the same for both profile in the bios so I don't know if it is possible to use a lower voltage for 2D profile. But even without lowering the voltage, the power consumption is reduced greatly by applying lower clocks

[benko]

yeah but i have 64bit vista,i dont know how to run atitray tools on vista 64???

also can i somehow chanbe in ATT when it is 2d to reduce voltage(to put 2d voltages just like ati powerplay when it realised that i am at idle)??

[Pyr0]

if u disable CCC, and use Rivatuner to oc your card powerplay will be disabled anyway
remember to use the enableclockcontrolcloning option in the power user tab so that both cores are overclocked simultaneously (RivaTuner\Overclocking\Global)


also, the latest public beta of ATT works fine in vista64

[Pederrs]

Thank you so much Unwinder for making this posible

I have been testing this "softmod" a lot and it works very fine on my GTX 295.

I got these results:
Std. clocks: 576/999/1242

Max stable overclock with default vcore @ 1,04V: 685/999/1477
http://www.gotweak.dk/Filer/OCTDK/GPU-V_Control/std.PNG

Max stable overclock with mod @ 1,26V: 770/999/1660:







I have made this little application to apply the softmod very easy:






Is someone interested in this kind of application? Right now im doing some alpha testing.

good job Pederrs

keep coding it

[jaredpace]

Nice work!!!

I've edited the OP, Any link to your app, pederrs?

what will i get with this??

i will try with ATT thx for link

[Biker]

Brilliant stuff!

The cat is truly out of the bag now....

My average 280 has taken on super powers with a smallish bump up to 1.25V and now thinks it's an overclocked 285

Well done to all involved and many thanks for providing me with hours of happy tinkering

Now I just need to find a home for all these shortcuts ....lol

[benko]

installed ATT got this messege




i think ATT is working fine, althouhg still voltages are changenable, how can i enable ATT 2d/3d settings??

when i restart pc voltages are again same (1.2/1.26),and not as before i set(1.1/1.35v)??

You have first two create two profiles in Hardware -> Overclocking settings ... (make sure the box "include clocks in profile" is ticked.

Then you just need to specify which profile is used for 3D and the one for 2D in Hardware -> Auto Overclocking ...

Also make sure ATT starts at windows boot in Tools & Options -> General Options ...

App looks great man
I would be very keen to give it a try

Thank you Here you go:

Download: GPU-V Control v.A2

But remember its all at your own risk to use the program


I will make a thread about it later today.

Fantastic Pederrs!!!!!!!!!!; will try it on my 4870X2 shortly!!! You definetely get a Hero Cookie for this!!!

EDIT; Just ran 3D Mark 06 @ 820 @ Mem 950, no probs. Left Idle the same 1.06 Boosted load to 1.3V Registers I used where 16 idle, 18 load.

[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
