problems with overclocking

i have a custom built machine its a asus mobo (p4p800-e deluxe) and a p4 3.0 GHz it has a max internal core of 3.6 but when i but it above 3.3 it hangs at random moments any ideas on how i can fix this? (if u need more info on my comp just ask)

 

The max is the fastest speed thay made in that series. Its not a guarantee that yours will run that or even half of that. Just ignore the "max 3.6" thing, your overclocking a 3.0... Have you tryed bumping up the Vcore a bit ?? Did you read the overclocking guide ??

 

yeah ive bumped the voltage several time to the point were im running near to 70c on 3dmark

 

70c ... did you read the overclocking guide ?? Or did you just go uping the core V ??

 

i no how to OC thats the problem im here for. im here because i wana no why just to get 400 MHz extra i gota add so much voltage to get it semi stable

 

yes i read the OCing guide. the other problem im also having is i no that PCs run on AC current and have fluxuating currents but is it normal for the vcore voltage to jump back and fourth between 1.3 and 1.55 when i have it set for a even 1.4?

 

that means your PSU isn't stable. That could be also what is causing your troubles. Having stable power getting to your components is VITAL.

Invest in a GOOD PSU (remember, you get what you pay for... get cheap... you get poor power).....

 

Yes, No voltage should fluxuate any more than about 0.05v either way. If this is the case and you are indeed experiencing fluxuation of up to 0.15 volts, this is most certainly your problem

 

The wierd thing is that it is a good PSU. Its a Thermaltake Purepower 480 (ive check it is enough to handle my comp) is there a way to check if maybe its a voltage problem in the PSU?

 

Not sure but you could try SiSoftware Sandra 2005 and open the environment monitor (temps/fans/volts) this will allow you to establish a time scale log then you can tweak with your settings and assess the graph as you do it. A lot better than EVEREST as you can monitor scrolling graphs on all the parameters and define the sampling intervals (1s > mins.).

 

Just to note, computers do not run off of AC, they are running off of DC.

Your PSU converts it

AC>>>>>PSU>>>>DC

 

if your voltage is jumping that much, then i'd suggest investing in a new, GOOD PSU (power supply).

The voltage should NOT be varying that much. That WILL throw off your OC and make things unstable.

 

Look just for interest sake what is your "Spread Spectrum" set to in BIOS under Frequency/Voltage Control?!?

If it is enabled any "jitter" will cause clock increases, your getting more than "jitters" and this would definately cause significant instabillity.
