if you are on your own, i recommend you read "Vmod basic" thread in this forum to give you an idea where to start

Classic - Cherry Semi CS5322

Pin 2 to ground.

Imnot sure on the exact resistance to use 50k starting high will be plenty, you might want to go lower to get resolution.

pin 2 to ground is about 4k at stock...

:confused: No such chip on this board.

This board has dip switches to change the voltage not bios.

I'll keep looking

I just tried this mod and it didnt work :(

If I drop the resistance over pin 2 the voltage goes down, but if I increase the resistance it just stays at 1.85 :(
Even cutting the pin didnt give me more than 1.85.

But ive got a board to mess with so ill try and work out another way later on in the week.

Cool no worries i'll have a read of that spec for that chip and read some more threads about Vmods;)


Cheers

Vcore mod a success.

A 56k resistor from pin 2 to gnd on the power socket gives
1.62V to 2.01.

I'm going to try another value resitor in a couple of days and see if i can get it to 2.1V.:banana:

A 18K resistor will get 1.84V to 2.28V :banana:
