It’s easy to increase the Vcore of the ENMIC 8TCX+, ENMIC 8TCX2+ and the EPOX 8KHA mainboards by soldering just one resistor to the right point to allow your CPU much higher frequency with the plus of Vcore.

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 Semiconductor CS 5301 voltage regulator (Three-Phase Buck Controller) have the pin 2 for the voltage correction (V-FB) to allow manufacturers an optimal adaption of the Vcore and we can also use this pin to increase the vcore to “our correct Vcore” :-)

We just need to solder a resistor from Pin 2 (V-FB) to Pin 17 (LGND) or any other ground. In my test i used a normal 1/4 Watt resistor with 220 K. It’s also possible to solder a SMD resistor from pin 2 (V-FB) to Pin 17 (LGND) where the SMD resistor have three digits to identify and 224 is 220 K.

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

Of course you can also use other grounding points as pin 17

In the above picture i’ve marked the easiest points with two 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 the other side of this cable to the marked pins.

Here is a picture of the already soldered cables for the resistor:

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.

This is a screenshot of the PC-Health menu BEFORE the modification at 1,85 Volt:

Before the modification !

But from now on if you select a Vcore of 1,6 V the real ! Vcore is 1,80 Volt and with a selection of 1,75 V you’ll get 1,95 Volt. You get the highest Vcore of 2,05 Volt if you set the voltage in your BIOS to 1,85 Volt (or connect all L7 bridges).

Here’s a screenshot of the PC-Health menu AFTER the modification at 1,85 Volt:

1,85 Volt becomes 2,06 Volt with a 220K resistor !

And if that’s still not enough for your CPU you could solder a smaller resistance value but the temperature would be much higher.

Anyway i’ve tested the mod up to +0,5 Volt (2,40 Vcore) without any problems.

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