unfortunately changing the FSB doesn't seem to make any difference

its now saying around 2.1v.. which if correct has moved from the 'bit of a pain' area into something which could cause damage to my cpu
does no one atleast know what i could use to insulate the pins?
and if this has any chance of working
is there anything else which could be responsible for this.. like overheating voltage regulators or anything? (although this thing has a massive heatsink on that so it shouldn't be a problem..?)
and are voltage readings ever wrong? i know temp readings often are but voltages?
FYI changing PSU made no difference.
i will have another look into software for changing voltages etc but last time i looked into this nothing worked for me i think.
