Why can some people overclock their AthlonXP 1600+ up to 1600Mhz+ without pumping VCORE?

I was browsing through Vr-zone's overclock data base for AthlonXP. I noticed that some of the CPU didn't need too much vcore pumping action at all, but some does.... Why is that? Does it have to do with the power supply unit?
I want to mod the mobo/8KHA+, so I can get my CPU up higher, but after I read the data. Now I am suspecting to switch the PSU....
What you guys' take on this?

Nope, all chips are different and some can overclock like crazy with little or no extra juice and some will run no faster then their rated speed no matter how much extra power you throw at them. Its luck of the draw.
 
It's pretty much 'luck of the draw' on buying cpus. Some o/c well and will accept high VCore - some don't.

My XP1600+ (AGKGA stepping) is unstable at any speed with VCore over 1.8V.

Hope this helps!
 
My new XP 1700 runs beautifully on a 140mhz bus without any additional voltage on my Shuttle AK31a board. I put together a system a few months back with an XP 1500 on the MSI KT266a board (whatever it is called) & it would not overclock no matter what I did with it.

I think besides getting a 'good clocking CPU', the particular motherboard makes a difference also. I had a PIII 700 that ran very will at 980mhz on an Abit VT6X4 (1.8v). The same chip would not POST at that speed (at any voltage) on my P3V4X.
 
Nothing to do with a Power supply. Wouldnt hurt your stability though if your ps isnt up to par. It all depends on the cpu and the motherboard, but mostly the cpu.
 
I'm running my XP 1600+ @ 1.63GHz on default voltage, I will even try dropping the voltage as much as possible to keep it cooler. This is with an sk6 and a 36cfm 80mm sunon.
 
it's not hard to keep cool, mine is at the low 40s under stress, but the lower voltage I can keep stable, the better 😀
