It’s very easy to increase the Vcore of Abit KR7 and KG7 (Lite, 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 !
The HIP 6301 is the Abit KR7 and KG7 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:
In the enlargement on the top right i’ve marked both important HIP 6301 Pins with red points. 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 !!!
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 about 2,05 Volt if you set the voltage in your BIOS to 1,85 Volt.
And if that’s still not enough for your CPU you could solder a smaller resistance value but on most boards is this nearly the highest Vcore without changing the OVP (over voltage protection) Pin of this voltage regulator.
Pay attention to the CPU temperature after increasing the Vcore !!!
