Is there a probelm with setting the Vcore lower..

Is there a probelm with setting the Vcore lower than the stock.....Mine is set at 1.65 I tried raising it to get the overclock I wanted and it wouldnt do it. I set the voltage at 1.625 and I still keep my 176 FSB fine but my temps droped a few degrees celsius!!!
So I wanted to know if there was any negative effects of lowering your vcore?

there is nothing wrong with lowering it the only thing it might to is decrease the stability.

yeah, in fact, its a commonly used method of lowering total system temps when people dont have a good way of dealing with temps.

Kewl I didnt notice any stability issues and took my cpu temp from 47 to 45 with no loads!!!

My xp1700 @ 1.15v. No problems whatsoever
