Overclock with MSI P6N Sli Platinum

Hi.
I want to know how overclock my system:

Mobo - MSI P6n Sli Platinum
CPU - C2D E6600
Cooler - Zalman 9500 LED with artic silver 5.
Ram - Patriot Extreme Performance 6400 - C4 EPP
VGA - EVGA 7900GSKO
HD - Maxtor 320 SATA 16 MB
WD Caviar 160 SATA
Case - Antec Nine Hundred with 2 fans additional

Now I have OC'd CPU at 334 MHz FSB(1334) and mult. 9=3.002 GHz and I've reached 356(1424) for 3.206 with voltages 0.125 in CPU voltaje and 0.025 in FSB above with no problems.
In Barranquilla is 32°C Idle(ambience temp here) and 45°C (Max) at load.

I want 2 configs for probe performance:

1.
CPU:3.2 GHz=400MHz X 8
Ram: 800 MHz 4-4-4-12 1T
FSB:RAM - 1:1

2.
CPU:3.2 GHz at 400 X8 or 356 X 9
Ram: 900 MHz or 1000 5-5-5-15 1T or 2T.

But I'nt found the correct voltage parameters.
Thanks for orientations in correct parameters and voltages respectly.
