Question:
Core Duo Processor Speed on 6400/E1505
I've got the T2300 1.66 GHz Duo Core processor and thought I would see what CPU-Z had to say about it and it says the cores are running around 998 MHz; I thought it would be running nearer the advertised 1.66 GHz.
In comparison I recently upgraded our old home desktop and installed an AMD Athlon 1200 processor, which was the most the mobo could accept, and CPU-Z shows the core running around 1207 MHz.
I assumed my six year newer advertised as 1.66 GHz Intel Duo Core processor would run quicker than the old 1.2 GHz AMD Athlon or am I misinterpreting it?

Were you on battery? Go to Power Settings under Control Panel and change it to Home, then re-check. The default battery setting underclocks the procssor to save power.

I never knew that, so I'll have a look. Thanks.

Yep..i'm in the same boat here... CPU-Z states that my core 1 runs at 997mhz and same with core 2. What is going on here???
I'm on AC power and have tried different power settings..ie; home/presentation etc..still doesnt do anything. Even disabled speedstepping in BIOS..no change here.. please advice.

try downloading notebook hardware control, it allows you to customize when you want it to underclock, maybe when on battery power to extend battery life, or max performance for gaming or other applications. they also have a feature that allow you processor to stay underclocked until you perform an operation that requires it to increase the power. hope this works for you good luck

As mentioned earlier it is most likely power save settings that are turned on. When you use power save settings it underclocks the CPU. And mjpartyboy - you can not compare an old 1.2ghz AMD system with a new core duo system. The ghz can not be compared. For example a 1.66 core duo runs at about the same speed as an Intel Pentium 4 3.6. It gets a similar score in super pi as the 3.6ghz P4. But you really can't compare a non dual core with a dual core. They are totally different.

Also, there are programs to take up 100% of processor...theoretically you should be able to run that and CPU-Z and you will see what the max speed is.

Also, if you use a program like RivaTuner, it will graph your CPU clock speed in real time, you can watch it fluctuate between 1-1.6GHz every split second based on what you're doing. My Computer tells me mine is ~900MHz as well, but it's really not.
