ASUS Maximus II Formula - new P45 king?

[529th]

So, i've finally tried finding the max my components will go.
custom H20 btw

Q9650 - FPO/Batch# L820B033
MIIF
DDR2 1000 2* 2x2 kit
Enermax Revolution 950

tries:
1 I've ran memtest86+ 2.11 1 pass at 500fsb 7 multi and it passed but would not boot
2 Leaving everything on auto except the fsb to 450 boots fine passes both small and large FFT's in prime 95, IBT running ATI tool (Scanning for artifacts) - vcore read 1.344 ~ 1.352
I've heard small FFTs are for CPU stability and large are more for subsystem & RAM testing more than cpu testings - is that correct?

I'm not sure about how to set my bios for 4.5Ghz - I've actually ordered another Q9650 thinking it maybe the weak link

Can I get a few suggestions from the experienced people here? Thanks
