That cpu is running with a multiplier of 11:1 to get 2.93GHz, with a bus speed of 267MHz. At 2.4GHz it would have a multiplier of 9. The mobo's I've worked with use a lower multiplier for speedstep. Now if you are running your bus at 216MHz or something like that then the maximum cpu speed would be 2.4GHz, but it would likely be a slightly odd number and not 2400 even.
If you run cpuz it will tell you the bus speed, cpu speed and the multiplier. If speedstep is working, then while you are staring at the cpuz screen it will probably show a multiplier lower than 11. Now crank up a program that puts a load on the cpu and watch the cpuz screen while you are doing this and it should show the multiplier and cpu running at full speed.
i watched it and my bus is 266.5 (1066/4) and when idle, multiplier is 9 @ approx 2400 and goes down to 6 @ 1.6ghz. i just did 1066/4=ans*11 and that is 2.931 so i in theory i understand it now.
i have to load up win 7 64 and then i will try it out with autocad or cs5 and see if multiplier goes to 11.
im not gonna lie im being pretty lazy on this next question instead of searching, but can one of you direct me to the the right thread (im sure it's created) on how to up my fsb on my cpu (if possible).. i do not want anything crazy or to over clock anything too much, but i would like to speed up the buss if safely possible.
