ABIT KT7, KT7A, KT7 Raid and KT7A Raid VCORE MOD

It’s very easy to increase the Vcore of Abit KT7, KT7 Raid, KT7A and KT7a Raid by soldering just one resistor to the right point to allow your CPU much higher frequency. Of course it’s necessary to be very careful if you’re soldering something on your mainboard in order not to kill your board. And of course your warranty void if you solder anything on your mainboard !

Therefore i recommend a good grounding and a soldering station with seperate grounding !

Before you begin to modify the Vcore you should lower the momentary Vcore at least about 0.2 Volt !!!

The HIP 6301 is the KT7 voltage regulator (multi-phase Buck PWM CONTROLLER). This voltage regulator have a pin (FB/pin 7) for the voltage correction to allow manufacturers an optimal adaption of the Vcore and we can also use this pin to increase the vcore to “our correct Vcore” 🙂

In my test i used a normal 1/4 Watt resistor with 22 KOhm (red, red, orange).

On this picture you can easy detect the positions of the two soldering points:

solder a resistor from R131 to Q19 !!!

In the enlargement on the top right i marked the two simplest places with an arrow. I didn’t solder the resistor directly to the board in order to modify the resistance value once again. Just solder the resistor to a cable and then solder this cable to the marked pins.

After this modification you should check the correct position !!!

If everything is soldered it should look like this picture:

Now put adhesive tape or a small piece of heat shrink sleeve over the resistor that it’s impossible to get a connection with other components. After this small modification your Vcore should be 0,2 Volt higher than you’ve selected in your bios.

So if you select a Vcore of 1,5 V the real ! Vcore is 1,7 Volt and with a selection of 1,75 V you’ll get 1,95 Volt.

You get the highest Vcore of 2,07 Volt if you set the voltage in your BIOS to 1,85 Volt.

Here’s the PC-Health menu display at 1,85 Volt:

And if that’s still not enough for your CPU you could solder a smaller resistance value but the risk to destroy the processor is very high.

Pay attention to the CPU temperature after increasing the Vcore !!!
