My Iwill mobo's vcore was set on Auto and gave a reading of 1.84v for my T-Bird 1.4. Because my cpu temps were a little high (over 50 C under load), I manually lowered the vcore to 1.65 and I got a 1.73 reading in return (I understand this mobo reads a little high) which resulted in a significant temperature drop with no loss of performance. So the moral of the story is 1.85 is probably ok if it's cool enough, but you might be able to cool it a little (and probably prolong its life a little too) by lowering the volts a tad. Just my 2 cents.
