can i make up from this that my card should do 400 core and 1200 memory ?
i can make the core to 400 with no problems but the memory is holding me back
got the card wc so temps on the core r no problems

what i wanna know is how can i (if it isn't already) see or make my card run @ 1.4 volt
to c if it helps the overclocking
i have read alot of treaths about riva tuner
but i think my english isn't good enough to fully understand all the subjects being discussed about it

so my 2 questions r
1- how to change the voltage (if needed) i think i do
2- can i c at what voltage my card is running in 3d mode
hope you guys/girls can help me out
