hey irangan.long time no see

ooh okay.thanks was slightly worried about the 12v rail.lol i should get a DMM to measure eh?

Actually its +/- 5%. any more than that, PC guarantee hang or KO already. Overclockers typically insist on +/- 1-3% for a bigger safety margin.
Infamous? Apparently you haven't tried AbitEQ or Gigabyte's Easytune.
Its not the software, its the monitoring chip on the motherboard. What do you expect from something that probably costs less than 3% of the motherboard's total manufacturing cost? As it is, everest is already one of the better software's as it sort of compensates for the inherent inaccuracy of the moitoring chips, others (especially those supplied with the motherboards, eg Gigabyte Easytune, Abit EQ) are often pretty inaccurate, sometims ludicrously so
