I just tried to do a volt mod on my gf3 and it seems to make my card perform worse! i can't run any 3d mark benches or i get artifacting and i will have to reboot. I have the card watercooled so heat is not the problem but what i want to know is how and where can i check to see if i am getting the correct voltage to my memory and core? I used to article from X-bit labs. Thanks.
