Q9450 OC / Temps / Settings

Are P35 boards any good for clocking Q9450? Or should I get a X48 for more FSB?

I cant even really say X48 is going to help out with Q9450... I have used 2 X3350s and a Q9450 and all of them got stuck at 440mhz and not a mhz higher.

If you look around everyone is having the same problem, starting around C1 stepping, and apparently according to Asus the Maximus/Rampage and all boards prior to them are not approved to work with the C1 stepping chips, this has been discussed in the X3350 Arrival thread, as well as the main Maximus/Rampage thread.

It seems to be a BIOS issue, but again there is the rare case that someone makes it over 440mhz FSB, and then those people have varied success in getting it stable as well.

At 450mhz regardless of settings/voltages I cannot even get into Windows with any of these chips... on a regular Maximus Formula, and a Maximus that was flashed to rampage even using the higher NB/CPU Ref voltage, as well as cranking out the VTT. However the only time I am able to get into windows with 450x8 is using the 266mhz strap, and then it boots fine, but the stability is an issue then because 8GB kits dont handle being overclocked too much too well.
