P43Twins1600

[Raidrusher]

Hello guys, first of all i want to apologize, if do some grammatical mistakes. It's not my native language
I finally want to overclock my PC after 2 years with ASRock P43Twins1600 mainboard and Q9650. I am sitting since yesterday the whole day with trying to overclocking and managed to understand this a little, but have strong headaches already. On the photos you see the values i already tested. After 20 minutes the system crashed with cpu-burn of CPU-Z (3700 benchmark points) . I could go back with the FSB called "CPU-Frequency" in this case, but i read great things about the Q9650, that it can handle 4GHz and more. My system crashes already with 3,3GHz and 44°C . What i am doing wrong?
The manual didn't helped to improve my results http://www.asrock.com/mb/Intel/P43Twins1600/?cat=Manual

If i increase the FSB, the BIOS freezes on the point where usually the SATA hardware gets loaded. Looks like this :

Need then to reboot 3 times, then the emergency mode kicks in and i can change everything. The whole day the same procedure again and again. My head hurts

Please help me.

How to overclock a CPU. Step 1 in overclocking any CPU that doesn't have an unlocked multiplier is to lower system RAM speeds as low as they will go. RAM speed rises along with CPU speed.

So my CPU multiplier is locked? I can switch between 6 and 9.
And its impossible to lower my Ram frequency, its already on the lowest as you see can i do something with the timings or voltages?

I don't understand why it crashes when i increase the FSB. More than 3,3GHz shouldn't be a problem. And my RAM has just 370 mhz. Stil 30 mhz to the optimal 400 mhz mark. I don't understand where the problem is

What have you adjusted Vcore to? 3.3Ghz is actually pretty good for stock vcore, if you haven't boosted it any. If your cooling is good, try 1.35V fixed vcore, and then try bumping the FSB in 5Mhz increments.

Yes, you were right. This was possible with stock voltage.
I tried what you said, but it was pretty unstable with more fsb. The core voltage with 1,35 V seems not no to be the problem. Maybe i should play with other voltages too? But which?

You didn't mention what cpu cooler you're using? That might be part of the problem.

 

[Raidrusher]

Air cooling. But why should it be a problem when the core is stil max. 45 degrees Celsius?

I meant what exact cooler are you using? An aftermarket (what model) or the Intel stock cooler?

Its the Alpenföhn "Brocken" with max 1500 rpm and 120mm diameter.
There are 4 fans in my computer. Sucks at the front, hot air comes from behind. Case designed by CoolerMaster

Yes, it's locked. Lowering it does not overclock your CPU, and if it weren't unlocked in a downward fashion, then it would have no choice but to run full speed 100% of the time.

To be able to run that motherboard at a 400 FSB, to have your CPU run @ 3.6 Ghz, you have to change the FSB jumpers on your motherboard. You'll need to short pins 1&2 on the FSB 1 pins, pins 3&4 of the FSB 2 pins, and pins 3&4 of the FSB 3 pins. All of this information is on page 24 of your motherboard manual, including a diagram of which pins to short. You'll have to change those jumpers before attempting to raise your CPU FSB in the BIOS.

I actually did it already, the jumpers are placed. I wonder why my system is so unstable. Maybe the motherboard is broken.
