Bij VR-Zone Hardware hebben ze een interessant artikeltje waarin wordt uitgelegd hoe je het voltage op de Abit KT7 RAID hoger dan 1,85 volt kunt zetten. Na wat aanpassingen kregen ze het voltage op 1,94 volt. In deze quote kun je lezen hoe ze het bij VR-Zone hebben aangepakt:
After seeing many nice reviews about the ABIT KT7 RAID, i am sure many have owned this board or thinking of getting this board. The ABIT KT7 allows the max voltage of 1.85V through the SoftMenu and many are able to overclock their Duron 700 to 1Ghz by setting VCore at 1.85V. When overclocking the Duron, VCore voltage play a very important part to which how much you could overclock and there is a limit to which you can set the VCore voltage. In this case, the ABIT KT7 allows a max of 1.85V and it would be interesting to see how much more your Duron can be overclocked if the VCore voltage can be increased some more.
I am still waiting for the EPoX 8KTA+ which allows VCore to be set to 2.0V and that would be real interesting. Nevertheless, if we can modify ABIT KT7 RAID to give us higher VCore voltage above 1.85V, it would definetely rock. Let's see how we can modified this board :
The VCore voltage is determined by the Microprocessor CORE Voltage Regulator HIP 6301. It allows voltages from 1.1V to 1.85V in 0.025V steppings. VID4 (Pin 1), VID3(Pin 2), VID2 (Pin 3), VID1(Pin 4) and VID0 (Pin 5) are voltage identifcations inputs from the microprocessor. HIP6301 decodes the VID bits to establish output voltage and it offers an over voltage protection of around 10-15%. In other words, we still can squeeze another 10% out of the max voltage of 1.85V that is 1.1 x 1.85V = 2.035V as long as it is within the limits.
