So we all know about overclocking. Some of us (me) have learnt from hard experiences and others have just read about it but never tried it. But no one has ever thought of, wait for it, underclocking a processor. So why would you want to do this? the only real reason woudl be to make the computer very very quiet. For instance if you had a home amatuer recording studio. Anyway a whole review can be found at PCStats
