Need guide to overclock my hardware.

Hi,
This is my hardware:
- GByte EP35-DS3L MoBo
- Corsair TwinX 4GB DDR2 8500 C5
- 1GB GByte 9800GTX+ N98XPZL-1GH
- Intel Q8400 Quadcore CPU

I will probably leave the GPU for now and focus on the rest.
I was going to use this guide:
http://www.overclock.net/overclock.php?file=articles/overclocking-guide.htm
but it seems a bit odd to me.

Can anyone help me out with what settings I should have on/off in bios and what speeds/voltages I should be aiming for.

Also what's the best stress program?

Should I up the voltage +0.1V every 10Mhz or something?

Thanks
JM

that guide is ok
also read http://www.computerforum.com/13239-cpu-101-a.html

are you crazy! no you nudge up the voltage only when you lose stability and only by the amount needed to restore stability. Suggest you avoid the vcore all together in your early days or till youve read up more

Haha, I did overclock on my old P4 630 from 3.0Ghz to 3.6Ghz but never touched Vcore.
Silly question, how do I know when I lose stability? on my old one I swear it was the heat issue keeping me back (hitting 70C on bad days).
 
You'll know trust me...;)

nnaaa, but serisously when its unstable, it will freeze/bsod or just not boot up at all stuff like that, so thats when you know to give that puppy more juice...
 
Ok, following the guide from the first post, I upped the FSB voltage up +0.3V put the CPU multiplier from 8 to 6 and kept the FSB at 333mhz.

Booted fine running Prime95 (64 bit) but Everest Ultimate says the CPU temps are:
Temperatures
Motherboard 34 °C (93 °F)
CPU 45 °C (113 °F)
CPU #1 / Core #1 61 °C (142 °F)
CPU #1 / Core #2 52 °C (126 °F)
CPU #1 / Core #3 55 °C (131 °F)
CPU #1 / Core #4 58 °C (136 °F)

(Speedfan shows same temps)

Now I'm guessing that the 'Motherboard' is the north bridge. But the CPU temps look really high to me =S
 
Motherboard is North Bridge

You have stock heatsink? If so those temps are not that bad but, do watch them. If you plan to OC alot you might want to invest in a better heatsink/fan.
 
ok, today I kept putting the fsb up 10mhz at a time booting into system to see if it boots restarting etc until I hit 440mhz.
I then ran Prime95 in the background whilst doing a little more research on the internet. After about 5-10 minutes my system froze and I could not do anything so I backed the fsb down to 430mhz and have been running Prime95 for 20 mins now with no problems.
Tommorow I will run it for longer and see what temperatures my chips get to and see if it is stable.
I still need to know what the max temp my northbridge can safely handle and which CPU temperature to go by?
Thanks
