I just got my XpertVisoin 8800gt Sonic Non Reference card with 3 phase power and successfully done the Vmod(Connecting a VR to Pin 4 of RT8802A and Ground). But the card shut down if i adjust core voltage to >1.35V So i did the vdroop mod(Connecting a VR to Pin 15 of RT8802A and Ground), but it didn't help at all, no matter how low i set the VR.
I need some Experts to help me please.
