Simple Question

If I raise the multiplier on my CPU, do I need to raise the voltage as well? If so how do I know how much to raise it? Do I also need to raise the frequency on my memory?
 
What type of processor are you using?-I know that with my amd 5000+ BE I just raise the multiplier and leave the voltage and memory on auto.
 
One tip for ocing the cpu or memory is to first lower the other or both down and then gradually increase either the memory clock or multiplier for the cpu until you reach the max where the system remains stable. Raising voltages when needed and only then is done in small increments and taking notes on temps and everything else.

For someone new to this take baby steps and watch temps closely. If you are running a stock hsf and not a good 3rd party cpu cooler temps will climb fast. That along with not touching any voltage settings for the time being are advised.
 
Im using a zerotherm cooler and temp is at 32.7C right now. The cpu is a Intel Core 2 Duo E8400 3.0 Ghz. the default on the motherboard was a multiplier of 7 at 333.34 Mhz Bus speed which was only giving me 2333.38 or 2.33 Ghz so I raised the multiplier to 9 which gave me 3000.06 Mhz (3.0Ghz). Out of the blue the computer randomly shut down. And thats when I was only web surfing. If I played a good 3D game she ran fine. So for giggles I raised the cpu voltage by 0.0125 volts and now shes running like a champ. What would be the cause for that? And did I do the right thing just to get my cpu to run at a stock core speed?
 
You may have a board not quite suitable for ocing. When seeing the system shutdown that signifies an unstable oc where you tried a small voltage increase to help to a degree. But you are still ocing with the multiplier and voltage raised.

To see the defaults restored simply go into the bios and load the optimized defaults with the assigned F key there or simply clear the cmos by popping the board's battery out for so many seconds. Or you could try manually lowering the changes back while in the bios. The other two methods are guaranteed correct however.

1. Sounds like you have speedstep enabled at the same time your tring to overclock. Go into the bios a disable speedstep EIST/C1E if your overclocking and change windows power option to always on..

2. Never listen to PC EYE.
 
My motherboard is a MSI P6N Diamond SLI 680i. In the Bios i can raise or lower the multiplier but only to reach the stock core speed. If I want to overclock I can adjust the FSB clock or Memory clock or I can enable the D.O.T. (Dynamic Overclocking Technology) which I can adjust by percentage.........

If the multiplier is set lower then stock, then I wouldn't consider that being able to raise the multiplier, as you aren't raising it higher then stock.

I checked again and speedstep is definetly disabled, at least it says it is.........

Did you check C1E?
 
You can leave them both enabled, when you run a intensive program or fire a game up the CPU will jump back up to stock settings. That is if your not trying to overclock and was just wondering why it was running underclocked.

I believe we both forgot to mention that, there's no harm in leaving those settings enabled, the processor is still going to run at it's full potential. It will simply run cooler, use less electricity, and last longer when you don't need the full processing speed of the CPU.
 
I,ve only built a few Core 2 systems,OMEGA might know better. But I think it should be listed under your Power Options. C1E halt state, it kicks in by using your System Idle process as a monitor.

I dont want to sound stupid but I am new at this. What is C1E and where do I look in Bios for it?

It varies with the motherboard, it may either be under the Power settings as StrangleHold suggested, or it could be under the Advanced settings page.
