Q6600 OC to 3,2 - 3,6 GHz on Asus Striker II Formula

[WojtulaPL]

First I would like to say hello to everyone, nice to meet you all, I'd like to be friendly and not cause any problems. 😉

But back to the topic. I've been trying to push my Q6600 to 3 GHz, but with no luck. Looking at various guides and settings I've finally made it to achiev this frequency. Now I'd like to go even further, to about 3,2 or better 3,6 GHz. No luck since now. I've been trying to to various things like increasing voltages, playing with multiplier - nothing good, I'm always stuck in POST.

I've already read various guides, including the ones available here or even official nVidia guide for 680i/780i chipset mobos.

Here's my rig:
Mobo: Asus Striker II Formula
Card: MSI GeForce 640 GT 2 GB
CPU: Core 2 Quad Q6600 2,4 GHz @ 3,0 GHz (G0 Revision)
RAM: 4x Kingston HyperX 800 MHz (working on 4-4-4-12 atm)
PSU: Probably one of FEELs 500W (yes, I know they're not good for OC, but I seem to be lucky, as this one hasn't caused any trouble for the last 6 years)

Voltages now are:
Vcore: 1,3625V
CPU PLL: 1,52V
CPU VTT: 1,36V

Rest of them is set on AUTO. Other settings, like Spread Spectrum or C1E or Intel Speedstep are disabled.

Any ideas? I'd be very grateful for any help. Also, If you need more info, I'll try to provide it.

Well...overclocking on a 6-yr old PSU is not a good idea..
raise PLL to 1.6
vtt to 1.38
lower your RAM strap
Isn't Striker an Nvidia chipset? might have fsb holes.

Yeah, it is. It's actually a 780i chipset.

Gonna do what you said and tell you whether it worked or not.

EDIT: It's no use. Still stuck at POST, no matter what. Tried with raising Vcore along with your changes but with no progress.

Sometimes it's best to get shared data from others.

Or you can always start from scratch.

So far so good. Right now I have 3,4 GHz, which is pretty decent. Got past the POST and into the system, no problems yet. Time for some stress test to check the stability. If it works, then I'll think of pushing it forward.

As for now, thank you all for help. We'll see how it goes now. ; )

EDIT: Busted. Crash on 3,4 at the beginning of a stress test, on 3,2 settings gets stuck at system load.

These are the voltages I was using for 3,4:

CPU Voltage: 1,3625V
CPU PLL: 1,54V
CPU VTT: 1,64
Memory Voltage: 1,9V
NB Core: 1,56
SB Core: 1,6V
1,2v HT: 1,2V
Bridge: 1,2V

CPU GTL_REF Ratio: +30mV
NB GTL_REF Ratio: +30mV
DDRII Contr. Ref: DDR2_REF+10mV
DDRII Chan. A Ref: DDR2_REF+10MV
DDRII Chan. B Ref. DDR2_REF+10mV

Any ideas, please? I've double checked these sites and that's the best setup. Its only disadvantage is that it's kinda unstable.
