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.
