Some help needed with overclocking

[Slaanesh]

I'm trying to do some basic overclocking with my E6400 but so far without much succes.

Specs:
C2D E6400
Asus P5B
2 x 1024MB OCZ DDR-II 800Mhz 5-5-5-15
GF8800 GTS
Antec 480W
stock air cooling


First of all, my system is rock stable at stock setting.
When I try to raise the bus speed only from 266 to 290 Mhz (-> Core speed from 2,13 to 2,30 Ghz) the system crashes after 1 min of Prime95.
I tried raising the vcore from stock 1,2 to 1,7V but it makes no difference.

Are there other settings I should adjust or is my particular chip not suited for oc'ing??

vcore 1.7 ? ya trying to make a BBQ or something ?

turn of all speed step and spreads off give enough voltage to the ram and gfx.

then take it easy with ocing try to get max clock with normal vcore then when u get the unstabil top clock of stock vcore then u can set it up slghtly.

Well first I tried without upping the vcore but it was equally unstable.
And how do I turn of all speed step and spreads off?

Two things you may want to try (if you already haven't):

-Disable static read control in the Northbridge configuration screen
-Configure the memory timings manually, using more conservative settings

Hmm.. Northbridge menu only shows "DRAM timings by SPD", "Initiate graphics adapter" and "PEG port config"; can't find static read control.

And can I do anything wrong by changing my mem settings from 5-5-5-15 800Mhz to 6-6-6-15 667Mhz? I'm not quite familiar with ram settings..

skip every FSB between 266 and 399

start at 400Mhz FSB 1.4v on CPU, 1.45v on NM, 1.3v FSB termination, disable speed step and C1E, disable spread spectrum, disable static read control. Set memory to lowest option (DDR2-800) manually set timings according to your set which would be 5-5-5-15. lock PCIE at 100 and PCI at 33.3 in the jumper free configuration menu.
Boot up and enjoy 3.2Ghz.

I guarantee these settings, but not temps. You NEED, NEED, NEED something other than the stock HSF to go past like 2.6 and keep temps down.
