Thanks Cibic. I got memory unlinked and I got them at stock freq. and voltage, canīt fit a fan over the ram anyway due to cpu cooler taking up space.
I have previously tried higher NB voltage, but found that "less is more", going down in the 1.50īs made it all stable. 1.35 vcore is not going to suffice either, thatīll barely take me to 4.05 GHz. I think I have one of those lazy Q9650īs. At FSB 1867 I canīt get a complete boot @ 1.46875 vcore.

But as you say, Iīll try īn pop in the values from the calculator, I put in a -40 as Y-item value, got that from the other recommended calculations. And Iīll try and up the Vtt from 1.32 to 1.34.

Thanks!
