Having trouble overclocking with my ASUS A8N-E.

Here's my setup:

3000+ Venice
1GB Corsair VS
Asus A8N-E, rev. 2.00, bios 1005/modded with NB47J
eVGA 7800GT
Seasonic S12-430HB
Thermalright XP-90

I have been following Zebo's A64 guide with little success. I set my RAM to 100MHz (200MHz ddr of course) and SPD timings, HTT multi at 3, CPU multi at 7 (tried 6 too), and set out to find the top HTT frequency. I went up by 5MHz increments, but when I hit 225, windows wouldn't boot. Both PCI(33.33) and PCI-e(100.00) are locked, i'm using SATA port 3, so they shouldn't be making an issue. I am wondering if my northbridge isn't doing too well because of the lack of active cooling, but the NB47J is much larger than any of the stock passive NF4 heatsinks. I have noticed the dearth of overclocking options in the Asus bios when compared to my friend's Ultra-D. I would very much appreciate if someone with more experience with this mobo could help me. Thanks.

Install the latest official BIOS (1006) and then load setup defaults. It should fix your issue.

EDIT: Make sure you ram has loose timings as well , 3-4-4-8 1T

I've been running nearly the same thing, and so far I seem to run into trouble around 250 with the stock chipset cooler.
I'm running bios 1008, mem settings at 2.5-3-3-8 1t.
When I was checking the max, I left the ht multiplier to auto.

a8n-e, 1gb corsair vs, 3000+ e6 venice, x700 pro, and running on ide drives.
Running stable so far on stock voltage with ht: 4x247, mem: 333mhz 2.5 3 3 8 1t multi: 9x

I'm running 255x10 1:1 ratio 2.5-3-3-7 2T on the same board, no issues. How are you coming to the conclusion your chipset cooler is preventing a higher FSB?
