Setting Voltage lower than CPU default?

Is there any problem with setting the voltage of a cpu below the default? Not by a lot of course.

Say an Athlon 1GHz (T-Bird) ............. I think its supposed to run at 1.75v, are there any consequences if you ran the cpu at 1.7v?
No overclocking involved of course.

Will the temperature be lower?
Will stability become worse?

I heard that the Athlon T-Birds @ 1.4Ghz run only on 1.7v... why is it higher for a 1Ghz?

By this info, I assum a 1ghz should be able to run at 1.7v instead of 1.75v.

If anything I've mentioned is totally wrong please let me know.

 
As long as you don't encounter stability problems, you will be OK. Temperatures will be lower. Lots of people under-volt in order to get a quieter system.

Just test for stability using prime 95 or whatever for 24 hours. If everything runs fine, you are all OK.

As far as the default voltages go, I'm not sure. But you can safely lower the voltage until you run into stability problems, then just up it one notch, and leave it there.
 
I lowered the vcore on my rig roughly 0.10 v to cool my T-Bird 1.4 down a little. My T-Bird was running in the low 50s, so I did a little digging and found that my mobo, which was set on default, was running it at 1.84v (not sure if that's accurate, but that's what it said). I gradually manually lowered the vcore setting until I reached 1.75v (had to set the vcore to 1.65v to achieve this). Together with adding an additional case fan (92mm on the bottom), cpu temps have dropped a average of 10c. Lowering the vcore did not affect stability at all. Good luck.
 
My 1600+ XP is stable @1.725v and overclocked to 1800+ speed, less heat. No problems @1.7v stock speed either.
 
cool thx for the info guys. I lowered mine to 1.7v and lost a couple of degrees Celcius. Runs stable too.
 
My XP 1700+ is running at 1.65 in my epox 8K3a. It won't overclock for crap (140 mhz maybe), so I figured I'd lower temperatures a bit (3-4 degrees). Unfortunately, I don't have a variable fan, so this isn't really doing me any good at all except maybe saving 50 cents on my power bill. The Duron 1.0 @ 1.9 V is a different story 🙂
