I just bought a Sony Vaio BX640P52 with a T7600 in it and I installed CPUZ to check things out. From what is see I am only using one core and that one is only running at 1GHz. Please help me, I don't know if I am just reading it wrong or what. I even ran Superpi to double check and it took almost 2 minutes to calculate pi to 2 million places. I'm no expert but that doesn't sound right for T7600. Any help would be appreciated

There's nothing wrong with your processor - laptop processors are designed to clock themselves down on battery to reduce power consumption and heat output. Intel integrates their SpeedStep technology into the Core 2 Duo, which dynamically adjusts both the clockspeed and the voltage on the fly. Whenever it needs more power, it will increase the clockspeed (it can adjust the clockspeed in different steps from 1GHz - 2.33GHz). So, let the processor do its thing.

2 minutes to calculate pi to 2 million places is a bit slow, though. My T7400 calculates it in less than a minute. Make sure you have the dual-core updates installed, and that you aren't running on battery or running any funny power profiles that would keep your CPU clocked at 1GHz instead of up to full speed.

Ah yeah, I must have missed the times of your SuperPi. I got around 54 - 56 seconds on the last T7600-based notebook I tested. Anyway, what I posted explains the clockspeed. Here's a link to the multi-core guide Pitabred mentioned:

Also make sure your power settings under Power Options in the Control Panel are set to "Portable/Laptop." -
Thanks a ton Chaz. That linked worked perfectly. I get a time of 54 seconds in superpi to 2 million digits now. Thanks again!
