Going for 4.0GHz, what should I change?

post #1 of 10
Thread Starter 
Hello, all!
I'm gonna go for a 4.0GHz Overclock today going from my 3.70GHz. I just have a few questions about the multiplier and such.

For the 4.0GHz, should I set it to 200 x 20? Or some other number? And my current voltage is at 1.175, should I up it to 1.2 or just see if it boots with 1.75? All the usual settings are turned off as well.

Anything I should touch on the VTT voltage? I've been hearing mixed opinions about messing with it so I'm somewhat unsure about what to do with it, thanks!

1.175 is really low. Some boards don't read the i5/i7s at 20 but will at 19/21 just as they may not read an even BCLK like 190 but will 191.
