P5WDH High FSB Resolved (Working) !!!

[DAK1640]

I am not a noob but I can't figure this one out. My objective is to Boot at 450FSB using 8X on an E6600...

- I have tried 2 different Memory types > Corsair & Super Talent PC2-6400
- I have tried various timings including 5-5-5-15 & volts upto 2.35

Specs in my sig are 100% stable with either Ram.
It seems as if 430 FSB is my max bootable with either Ram? Whether using 9X or 8X
I have tried upping Mch & ICH along with term voltage.
I have never upped the vcore though, if I can run stable at 400X9 , the I would think 450 X8 at same vcore should be possible right? Can anyone help me achieve a 450 X 8 OC ? I know for a fact I can run stable at 434 X 9 with a higher Vcore. Is my problem with Bios 1503? I greatly appreciate any assistance or suggestions. There is no way I have 2 sets of Ram maxing out at approx 430 FSB...
