Shamino posted a thread on the kingpincooling forum, where the ASUS R&D have figured a way to publish voltage modifications for graphics cards.
These include control of the VGA loadline, switching frequency, OverCurrent Protection and core voltage. The picture above shows what to solder with the Rampage IV Extreme. These headers are then plugged into the video card, in the below shot. There are some steps you should follow:
Do Not plug in the header before boot.
After Boot and go into OS, plug in header
Open Digipower CNTRL (install from CD)
And a few more, too:
you can set load line, Switching Freq, OCP, it will be set with the CPU's vcore, so suggest set LL Extreme, Switching Freq 500 to 800, disable OCP (this will also be used for the VGA Vcore)
If you also wanna adjust vcore of VGA, u can open up Turbo V and adjust the CPU Vcore together with the VGA vcore. VGA vcore will be 100mv lesser than what you set on the CPU. For eg, 1.40 will give 1.30 on VGA.
After adjust and ready to bench remove header. Settings hould be kept even at reset unless you shutdown.
Do not have the header plugged in at boot as it will make the system stop booting.
As always with things like this, take precautions and we cannot be blamed for destroying your hardware. Caution is always required, as this is not for the faint-hearted. But, if you're daring enough to do this, please post your results on the TweakTown Facebook page!
