Hi, while I am an active reader of OCF, this is my first post. Anyway, I have recently purchased a new computer for gaming and I would like to overclock it. I have read the guide about overclocking the C2Qs, but have a few questions. First of all, here's my setup:

EVGA 780i SLI mobo
Core 2 Quad Q9550 (C1 stepping)
Zalman CNPS 9700 110mm cpu cooler
OCZ HPC Reaper 2 x 2GB DDR2 1066 5-5-5-18
EVGA 9800 GTX
2 x 640GB WD Caviar Blue (RAID 0)
LG 6x Blu-ray drive/20x DVD-RW burner
OCZ GameXStream 600W
Antec 1200 Full Tower Case

I'm would like to try to hit 3.4GHz on air, which from what I've read that shouldn't be a problem. But should I keep the voltage at stock and just OC the FSB to 400 or should I increase the voltage too? And will my mobo be able to OC to 1600? (1333 native) Also, I know this is a memory question, but it's related. If I do set the FSB to 400MHz, and since I have 1066MHz RAM, would I get better performance if I overclocked it to 1200MHz (2:3)(if that's possible?) or if I underclocked it to 1000MHz (4:5) or even lower 800MHz? (1:1)

Sorry for the all the different questions; I'm still new to overclocking :confused:
 
I had to increase the cpu core, cpu fsb and nforce spp voltages a little bit for 3.4GHz on my q9550 on an EVGA 750i FTW to get stable. And yea your motherbaord will have no problem with 1600.
