CPU Overclocking "NOT WORKING"

[Spitfire7]

Hey guys, I will give you my specs before I ask the question.

Core 2 Duo E6600 2.4GHz
2 BFG GeForce 7600 GT OC (SLI)
2GB Corssair XMS2 DDR2 800 (4-4-4-12)
700w OCZ power
eVGA 680i Mobo
320GB Hard drive 16MB cache 7200RPM
Windows XP

So I thought it would be easier then it was to Overclock my CPU. I read through all the topics, the tips, and the guides. I guess its not as easy as I thought. I am using my motherboards Windows NVIDIA Control Panel which allows me to do just about everything for the motherboard. This includes changing voltages, overclocking CPU and GPUs.

So the problem is I wanted to start overclocking my CPU at about 3.1GHz. So I moved FSB Reference slider in my windows base NVIDIA Control Panel (Maybe thats the problem I am doing it in Windows and not in my BIOS) to 346MHz which puts my core frequency at 3,114MHz and my FSB Frequency to 1,384 and my Memory bus to 1,038. From reading other forums I heard that I can keep my 1.2875 voltage and it should run just fine. As soon as I hit apply the computer locks up. I tried changing the volts to 1.325 which was recommended from someone else and still I get a lock up as soon as I hit the apply button. I began to get creative and every setting I chose would still lock it up whether it be drastic or minimal changes. What am I doing wrong? Please help.

I have no experience from oc'ing in the Nvidia Control Panel,but my guess is that you've set all your settings too high from the start. You have to gradually increase the speed and find out where the limit is for each component.I would suggest you oc from the BIOS and read the sticky for overclockin C2D cpu's at the top of the forum.

Don't run your memory up that high. It's rated for 800 MHz and you're running it at 1036 without upping the voltage or loosening the timings?

If you want that overclock loosen up the timings to like 5-5-5-15 in the BIOS and then overclock via BIOS until you get there (I'd advise downclocking the CPU so you know it's not a problem til you get the memory stable that high).

Otherwise I would just drop the multiplier to 1.2:1 and run it at 415 (it MIGHT do that at stock settings) and up the voltage. Or run it at 1:1.

im gonna try this, wanna up my 800 a bit, but being easy on it to see stability.
