OK so ive had this pc for 3 years and i decided id overclock it, it was my first try at overclocking and i got my i7 930 at 3.74 GHZ and i keep hearing 3 clicks from inside the case whenever i boot up but everything is stable, ive run prime and IBT for 8 hours each and everythings stable, i have my vcore at 1.25 and my ram volts at 1.60, vtt at 1.20, ive kept the ram at default frequencies of 1066, my board is GA x58a-ud3r, ram is some apacer brand, can anyone shed some light on this?
