i worried about the speed
ok running 3.7GHz is fine, it's designed to do that automatically with turbo. People have overclocked that processor in excess of 4GHz and over so 3.7 isn't hurting it at all. However there could be something else going on as turbo only kicks in when the extra processing power is required so check background running processes and run a malware/virus scanner checking there isn't anything happening you aren't aware while you think system is 'idle' but it's not.
my bus speed is 99.76 its that ok ? i cant get it stable to 100.00 even i set the bclk to 100.00
what are you talking about? are you trying to overclock?
