Hp overclocking a x2 4400

[Ka0ticMind]

Hi Guys...need some help overclocking my system, tried in the past but not had much success with it...so thought i would try see how if i can get a bit more out of this x2 4400 cpu.
System specs:

AMD Athlon 64 X2 Dual Core 4400+
Asus A8N-SLi Premium nForce4 SLi Motherboard
Corsair 2GB DDR XMS3200C2PT TwinX
Sapphire ATI Radeon X1900 XT-X 512MB Graphics Card
Creative Sound Blaster X-Fi Xtreme Music
2x Samsung SpinPoint P HD080HJ 80GB SATA-II 8MB
LG GSA-4167BA 16x16 DVD±RW Dual Layer ReWriter
Antec Super LANBOY Aluminum Super Mini Tower Case
Enermax Noisetaker 600W psu
ThermalRight XP-120 heatsink & Akasa 120 fan

Seems to be quite a few options in the bios on this motherboard...so any help would be really appreciated, i'm running the memory at cas 2 3/3/6 ...do i need to slacken the timings off to be able to overclock it?, plus what voltages shall i start off with, and what is a safe level to go upto with the heatsink and fan i have?
I appologise in advance for another thread like this..but i really could do with the help.

Kind Regards N

Don't you dare overclock it!

Treat it nicely, wrap it in cotton wool, talk sweetly to it and sell it to me instead

LOL dropped you a mail mate.

Thanks for the reply mattio1980 would i need to change the memory timings to run at 240 x11 multi and x 3 ? and also what voltage should i start out at...tis just to auto at the moment.
