We're happy to announce that we started the Afterburner 1.6.4 Beta testing process, in this version we have early support of voltage control with NVIDIA GeForce GTX 470/480 along with other many exciting features.
Afterburner 1.6.0 Beta 4 is released, in this version Unwnider add 2 exciting features. One is highly expected GeForce GTX 480 over-voltage function, the other is special "CaptureVoltageDefault" for AMD 5800 series BIOS issue.
[GeForce GTX 480 Over-Voltage]
In Afterburner 1.6.0 Beta 4, you can adjust the voltage of GeForce GTX 480 from 0.825~1.125V. It's not very big adjustment range, but considering egg-cooking capability of GeForce GTX 480, it is safe to stay in this range.
GeForce GTX 470 over-voltage support will be ready in next version.
[Capture Voltage Default]
There are some negative comments on newegg about R5830 Twin Frozr II(http://www.newegg.com/Product/Produc...7491&Tpk=R5830), I will explain what really happen and what "Capture Voltage Default" function is.
In Afterburner, we use a hidden BIOS ID database to identify each card and define voltage adjustment range. The negative comment is right, the PWM on R5830 Twin Frozr II is up6206 which doesn't support I2C voltage adjustment, that's why we add another up6266 I2C chip to support over-voltage. All MSI R5800 series support over-voltage, we can guarantee that!
The trick part is AMD provide us different kind of 5830/5850/5870 GPU -- high voltage and low voltage one. There is NO way to tell which is which by outlook or BIOS ID, they're all the same except different GPU default 3D voltage. Also different GPU use different I2C address to adjust voltage, so it cause us a lot of trouble for the last few weeks, because we can't use database to specify different I2C address on exact same BIOS ID graphics card.
Right now R5830 Twin Frozr II still has this bug, some of R5830 Twin Frozr II can be detected by Afterburner with over-voltage function, but can't adjust it. If you encounter this issue, just follow below step and build your own database specifically for you card and fix the problem once for all!
1. Edit MSIAfterburner.cfg
2. Change AllowCaptureVoltageDefaults from 0 to 1
3. Run Kombustor in windowed mode
4. Press <Ctrl> + <Alt> + <Shift> + <V> to capture voltage
