CPU Voltage questions

Hey guys i plan to OC my 3000+ as high as it will go in about a month
Motherboard will be DFI LANPARTY UT nF4 Ultra-D Socket 939 NVIDIA nForce4 Ultra ATX AMD Motherboard

I was just wondering how voltage plays a part in the whole sceme of things.

How much is too much?
How does it influence the CPU speed?
Will i even need to adjust it?

Anything would help,
thanks
 
Yes, more voltage is needed for more stability. Don't go too far up though. Do it in little increments. ANd only do it if your not stable.
 
If you want to get your CPU to run at 2655 Mhz aprox. you will need a High Voltage value such as 1.550v. Maybe your Cpu needs more voltage than others...increase the amount of voltage but do never go beyond 1.6v!!
For example, mine, a 3200+ Winnie is able to run Prime95 Blend test rock-solid at 2633 Mhz with 1.57v on AIR. I am running it at 2628 Mhz with 1.57v, not at 2633 Mhz because I can't get there trough the BIOS settings, only with CLOCKGEN. 2628 Mhz is the nearest value to 2633 Mhz I can get with the Bios (292 x 9). At 2636 Mhz (293 x 9) my CPU wouldn't run stable in Prime95 no matter what voltage I used, It failed after 2 hours.
Run Prime95 small FFTs for at least 6 hours to check if your CPU runs stable, once it does, Run Prime95 blend test so your RAM memory is also tested.
Please read Zebo´s Quick and dirty A64 Oc guide, it may help you!
