    Hi. I just got my 17" MBP SR with the Hi-res screen and 7200rpm hard drive. I'm a happy camper. :) No dead pixels, no problems whatsoever. Until.... I installed CoreDuo Temp since I was curious to know what temperatures I was getting during idle and full load.

    My problem is that CoreDuo Temp reports my CPU at 1.5Ghz on idle and 2.0ghz on load. I had also installed miniStat 2 v1.89 just to verify this and I am getting exactly the same results. No matter what I do, I can't get the CPU past 2.0Ghz.

    I have the power adapter plugged in, have set energy to "better performance" and Im still not getting anthing above 2.0Ghz. Is there a utility that can load up my cpu to its max. I just want to be sure that there is nothing wrong with my machine.

    By the way, system profiler reports my processor to be a 2.4Ghz Intel Core 2 Duo. What gives? Or is there something wrong with my method of testing. Thanks in advance for any input.

    Your processor adjusts its clock speed depending on load to save energy.

    Thanks for the reply. I do understand that it throttles back to save energy but it seems no matter what I do, I can't get it past the 2.0Ghz mark. On my previous Rev B 17" MBP, i did not have to do much for the CPU to hit its max of 2.33Ghz. Maybe I am not stressing it out too much? Any suggetions on a program or utility that I can use to fully load up my CPU just to see if it will max out at 2.4Ghz?

    Thanks again.

    I had the same problem/question with my MBP SR 2.2 15"... then I found out that CoreDuoTemp is not updated for the new processors and the reading is wrong.

    Again, thanks for the quick reply. Any idea on what utility I can use to test my CPU's current frecuency/speed?

    Thanks.
