Rampage Formula Won't Post At 366 FSB

554 Views 5 Replies 3 Participants Last post by  nolonger
I've been recently trying to find my max stable FSB on my Rampage Formula to get the most out of my overclock, but it steems to cap out at 366MHz on the FSB.

It seems stable at 350MHz 1.25V (although further testing needs to be done), but I can't get it to post at all at 366MHz.

maybe a FSB hole? did you try higher than 366, like 380 or 400?

I tried 1.31V max. See the template.

Tried 375 and 400, nothing.

I'm thinking you need somewhere in the neighborhood of 1.55 volts on the NB. I don't think 1.31 is going to cut it, or it definitely wouldn't on my Maximus Formula, which is basically the same board.

Here's some numers from when I was OC'ing a Q9550 (nothing in pink would work, just a prediction of what I was going to try)
