Ok, try setting the CPU frequency to 400 and see what happens...

with 1066 memory option selected (1:2 ) ?? PCI Express Latency i have heard that 100 is the best value.. should i put it or leave it auto? and should i change anything on System options? like disable speedstep C1E suport set multi of cpu or anything? Just ram Option and 400fsb?

400 is around 3.5ghz for mine or roughly cant remember try upping it to 420fsb and around 1.4v that should give you a stable 3.6ghz which is damn sweet for that chip no bottle neck wink.gif

Leave PCI Express at 100 or Auto, either one. Keep speedstep on, this allows your CPU to downclock when not under load.

And keep RAM at 800 option if you can. I may still not understand how your motherboard works completely, but see if you can set both RAM and CPU to 400 FSB at the same time, if that makes sense.

So, 800 MHz for ram, 400 bus speed for your CPU => 400 MHz x 9 = 3600 MHz.

Here are the settings I would try:

AI OVERCLOCKING: [Manual]
CPU FREQUENCY: [400]
PCI EXPRESS FREQUENCY: [Auto]
DRAM FREQUENCY: [800MHz]

Northbridge Configuration -> Configure DRAM timing to SPD: [Enabled]

All other settings on [Auto] or on their default values.

This should give your CPU an overclock of 3.6 GHz. If you can't boot to Windows, increase the vcore incrementally up to 1.4V.

Couldnt boot on windows using this.... :/// and i have these optioons about voltages: MCH Voltage ( auto 1.25 , 1.40) Memory Over voltage (auto wich is 1.8v) ( and from 1.85 manualy to 2.24 ) Now Last option is Vcore Overvoltage options available: (+0mV +50mV +100mV +150mV) WIch of these should i try with ur last settings above?

Ok, memory voltage should be fine, since they're designed to run at 1.8V.

Try leaving MCH voltage on Auto, as I'm not sure what it does, and go for vcore overvoltage +150mV.

This is a photo of my bios with my Q6600 in at the moment.

That has it stable at 3.6ghz

http://valid.canardpc.com/show_oc.php?id=2105015 as proof amitably I upped the vcore to 1.5v because I intend to push to 4.0ghz tonight tongue.gif

Ah, so MCH stands for memory controller hub (which is the northbridge). Like someone posted a page or two back, you shouldn't need to change it from auto, as your memory is running at stock settings basically.

If you can't boot with +150mV at 400 CPU bus freq, you may be stuck. It doesn't look like your motherboard supports increasing the vcore any higher than that. We may have to scale back your overclock. frown.gif
