I'm a little confused about something. I bought an Athlon XP 1600 and it only clocks at 1.06 Ghz. I thought this chip was supposed to clock at 1.4 Ghz?? I used SiSoft Sandra and BurnIn Test. I did do something stupid and forget to put heat sink compound on at first. Would that cause the speed of the processor to go down? Please help cuz I'm confused.
