Did you unlock the L7 bridge(I think its the 2nd from bottom one)? If this is unlocked, you'll get a constant voltage of 1.85, which usually reads a little higher than what its set to. If you bought a pre-tested chip(shame on you), this bridge is probably unlocked. At least it was on th epre-tested chip I bought(shame on me). If you want to unlock it, just take a little nail polish remover or rubbing alchol to it, that should clean off graphite or conductive pen gunk.
