Can some one help me?

Connecting pin 8 (feedback) of the RT9203 to ground via a suitable resistor should raise the output voltage of the regulator.

Connecting pin 4 (feedback) of the RT9226B to ground via a suitable resistor should raise the output voltage of the regulator.

I don't know which regulator controls the mem/gpu voltage, so you will need to find some readings from the capacitors near the regulators on the card to determine which regulator controls which voltage.
