I just got my Q6600 G0 today and using bios 1215 my P5B Dlx posts as : 4050MHz ( 450*9 ) when I really have the system @ 450*8 witch is 3600MHz !!!

Anyone with this problem ?

With my E6400 it didn't have any problem detecting the multiplier change.

Is there any news bios after 1215 ? And is the P5B Dlx goods for the Quad's ??

Thanks.
