Description:
	This program allows easy GPU voltage adjustments on GPUs with volte
	rra-based voltage regulators and it uses the award-winning and criti
	cally acclaimed RivaTuner for these adjustments.

	WARNING! By using this program, you agree that the author is NOT
	responsible for ANY consequences as a result of using this program.
	You, the user, are liable for any damages occured. Be a smart overc
	locker and monitor those temperatures and voltage levels!

Compatibility:
	Most GT200 GPUs are supported, some G92 GPUs, and all RV770/790 GPUs
	above 4870, and several custom PCB boards. If you aren't sure, just
	try it and see if it works ;)

	Tested on: Visiontek Radeon HD 4870 X2, BFG GeForce GTX 295,
		   SAPPHIRE Radeon HD 4870 X2, ATI Radeon HD 4890,
		   ASUS EAH4870 X2 Tri-Fan, and more!

Requirements:
	- RivaTuner (v2.24 is the minimum version)
	- A compatible GPU with volterra-based voltage regulators
	- Latest GPU drivers
	- A modern Windows-NT based operating system (XP and above). Both x86 and x64 are supported.
	- Microsoft(R) Visual C++ 2008 Runtime (x86), can be found here:
  	  http://www.microsoft.com/downloads/details.aspx?FamilyID=9b2da534-3e03-4391-8a4d-074b9f2bc1bf
 	- Microsoft(R) .NET Framework v2.0 (minimum), can be found here:
  	  http://www.microsoft.com/downloads/details.aspx?FamilyID=0856EACB-4362-4B0D-8EDD-AAB15C5E04F5

Instructions:
	First, you need to put the full path to RivaTuner in RivaPath.txt (with a
	trailing backslash [\]).

	I designed this program with automation in mind, so most settings should
	already be correct. But if they aren't you can correct them. For example,
	in the GPU Information section, if the selected voltage is not the "3D"
	performance voltage, please select the correct one. You can change the
	"Current GPU #" drop-down to anything you want, it's for your information.
	What you set under "GPU Voltage Tuning" for "Number of GPUs" will affect
	which GPUs' voltages get set. Again, it should be automatically detected.
	Voltages available range from 0.8625v to 1.6000v, so be careful what you set!

	If all of the voltage VIDs are displayed as "0xff", then you selected a
	non-existant GPU under "Current GPU #".

	* Note: Do not have RivaTuner running prior to running GPU Voltage Tuner, it
	  will refuse to work properly.
	* Also, if you are unsure whether the automatically detected and selected vo
	  ltage is correct, you can check by loading up a full-screen game with GPU-Z
	  or RivaTuner logging the GPU voltage in the background. If it is incorrect,
	  simply select the correct load voltage.
	* If you wish to set voltages higher than 1.45v, you'll need to unlock higher
	  voltages through the Advanced Settings menu by right-clicking the voltage
	  drop-down.

I made this for even easier use than the other programs introduced by other fine members of XS. It works more automatically as well.

Enjoy! Please test it!

You're missing these:

[i found nemo]

lol i just deleted my post. trying it out with 2008 runtime

i'm stupid, sorry for my stupid :P

[AgentGOD]

Please give feedback people!

[Mean Machine]

It says my HD4890 doesn't have a Volterra regulator and thus isn't compatible.

You'll need to apply that special patch to RivaTuner v2.24 for RV790 (can be found in the 4890 Overclocking Guru3D article).

For saving your time, the link is here to the file:

Here's the article itself if you need it:

Oyeah, probably should've read the readme first. :P My bad.

[NaMcO]

Works just fine with my other PC's HD4890. Set to 1.3750v and able to attain 1GHz core speed easily. Used in Windows 7.

So it correctly detects the load voltage, and number of GPUs?

What about your GTX 280's?

Completely. All i had to do was set the voltage to 1.3750 (value i came up with previous tests) and Voilá

Here's a screenie:



The GTX280's are in another build which is undergoing a huge modification, i can try them individually here later on (mobo doesn't support SLI).

[AgentGOD]

Excellent, now we know it works on RV790s and single-GPUs properly Thanks for your feedback!

Only GPU I was able to test personally was my 4870 X2, and that's dual-GPU obviously

[spajdr]

Not working here with my Sapphire 4890 1GB Vapor-X.
I used modified config to rivatuner.
Still getting error that i dont have volterra regulator.
(Windows 7 x64 7201 version).
Is there something else im missing or just my card dont have volterra regulator?

[dinos22]

thanks for this

just tried it and it works great

Asus 4870X2 Tri-fan EAH edition

[dinos22]

btw VMEM voltage is showing in Rivatuner monitoring

does it mean we could adjust it via software as well

could you integrate that as well PLEASE

[Lestat]

doesnt work on my Evga GTX285, says i dont have the Volterra
Windows 7 x86

[Royalk]

still not work with GTS 250 (G92) with the RT8841 PWM

[Shahryar_NEO]

it doesn't work on my HD4850 ! ( non of these voltage tuner softwares work on this card until now ! )

[The-Fox]

I can't set any voltage to my Sapphire 4870X2 - "Error setting voltage X.XXXX to GPU0."
Restore for voltages fails too - "Error Restoring Voltages"

Any Ideas ?

Aside from that, great initiation AgentGOD, once again you proved to be very very helpfull to the XS community

That's because it doesn't. NVIDIA switched the VRMs on you on the GTX 285 to a cheaper one that doesn't support software adjustments.

Did you try running the application as admin?

[SNiiPE_DoGG]

so are you guys still havign to apply 3d load before setting the voltage with this program or does it bypass that step?

[AgentGOD]

Given that the auto-detection works correctly (that's also the kind of feedback I'm looking for), it should bypass that step and automatically select the correct load voltage. If it doesn't you can always manually select the correct one.

[SNiiPE_DoGG]

ok I dont have my 4890's running right now but when I do I will test for you

It needs to have volterra regulators :P

-------

Oh by the way, the owner of Guru3D (which as you all know is the official host of RivaTuner) has asked me to take down the link to the utility for user safety reasons (prevention of people setting 1.6v on stock cooling and killing their cards).

What do you guys think? We should have a vote on this.

Adjusting VMEM Voltage would be awesome

[SNiiPE_DoGG]

why would you remove the utility? if someone is dumb enough to set 1.6v to their card and kill it then they deserve a broken card. It's not like they can do anything about it killing their card.
