Hi CryptiK,
Thanks again for your answer!!!!
Yesterday, I try to reach @4.0Ghz, but I had some instability ( maybe memory - 1.9V - 1081 MHz ) ....and the temperature is about 67ºC in Load!!:o
Right now I´m using 1.18 as a VTT... is all right?
And if I try to reach again today the 4.0GHZ, I was thinking in 1.25 for VTT.. What do you think?
