newest version is 1.3

It works on HD3870, some hd3800's, most GTX200's, 9800GX2, most HD4800's, hd4870x2, hd4890. GTX260/216/275/280.

Doesn't work for 8800gt, gtx285, some 8800gtx's

Use caution when increasing voltage, and USE AT YOUR OWN RISK.

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:

Pretty neat. I wouldn't want to do it on mine though. The stock HIS cooler is crap on my 4870.

Interesting, might give this a go- I thought most of the 4870's/ X2's were physically limited voltage wise at about 1.26v.

It works! Just tested a few mins in Crysis at 1.3v and it is correctly reported in GPU-Z as 1.3v on both GPUs- MSI 4870X2. This is awesome, now to see how far this X2 can go on water

Isn't this more or less the same as the EVGA Voltage Tuner, except that it works on some ATI cards as well?

I bet it doesn't work on my 9600GT.

yes It's like an unlocked evga voltage tuner that works on any brand or any make, (ati & nvidia) as long as the card has programmable voltage regulators (vrm's). These programmable vrms are made by volterra and found on higher-end (except gtx285) and some non-reference boards.

sylvannas: your limit is 1.37v per gpu. unless OVP modded. I'd like to know what kind of Overclock 1.37v will get you on a watercooled X2. Edit: you might have to choose 1.3695v or something.

I chose 1.4v and it came in at 1.38v in GPU-Z so that looks to be the limit. A shame though as it seems the extra voltage is not doing anything for me as I am capped at about 860-65mhz core- anymore and I get artifacts everywhere in GPUTool and Crysis. Temps are no problem, stock voltage OC'd hits 33c load, at 1.38v load is just hitting 40c.
