Mach II OC Prob.

[Yawl]

Hello everybody.
I just got my Mach II and was looking forward to OC my P4 2.4-800, beyond the 3GHZ.
I'm using 2*512 OCZ EL 3500 on a Asus P4C-E-deluxe.
The problem is that when my FSB is above 252 the com. wont boot. I even put the memory to SPD so i woulden't crash because of too fast timings.
I can't choose between 1:1 5:4 3:2 in my BIOS, but i think 400Mhz 320MHZ and 266MHZ is the same??! Any way, I've tried them all. Its set on auto right now.
The CPU Vcore is at 1.600 and the ram at 2.85V.
Any ideas??
Thank you and sorry for my poor english (I'm from Denmark)

Set Dram frequency to 266mhz, then return your memory and get the OCZ pc4000 copper series. Next increase vcore to 1.7, then replace the N.bridge cooler with a Swiftech MCX159P, next thing what power supply do you have?

-Intel PIV 2.4C @ 3.84G -Asus P4P800 -OCZ Copper 2x256 4000EL memory @ 275mhz 3-4-4-8 -Sapphire 9800pro @ 490/780 -SB audigy -80G Maxtor Diamond Plus9 Ultra ATA-133 hdd -450 Enermax PSU

I have a active cooler on my NB, so thats okay
And I have a Antec truepower 550W so that should also do.
So it must be the ram that is the problem??!
And thanks for the reply.
