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.
