CPU speed dropped after installing RAM

\015 I installed more RAM on a IBM Lenovo T60. I was currently had 1GB and installed an additional 2GB for a total of 3GB. When I go to 'my computer' and 'properties' I noticed that my cpu GHz dropped on my cpu speed. I can't remember what it was orginally, but I could have sworn it was > 1GHz and now it's like 900 MHz. Could something have changed withint he bios? Or why would this happen? I'm also trying to find out what I can change it back to and how. My cpu is an Intel Centrino Duo.\015\012\015\012Thanks for your help!\015

Ok. Fear not. You CPU is running at its native speed, it is the fault of Windows reporting the actual CPU speed. If you stop in the BIOS, the real speed will be reported there, the same if you run Linux.
Hi,
To make sure that the SO-DIMM is installed correctly, do as follows:
1. Turn the computer on.
2. While the “To interrupt normal startup, press the blue ThinkVantage button” message is displayed at the lower left of the screen, press the ThinkVantage button. The Rescue and Recovery screen opens.
3. Click Access BIOS. The System Restart Required window is displayed.
4. Click Yes. The computer restarts, and the BIOS Setup Utility screen opens. The “Installed memory” item shows the total amount of memory installed Replacing memory in your computer. For example, if your computer has 1GB of memory and you install a 2GB SO-DIMM in it, the quantity shown in “Installed memory” should be 3GB.

How do i change the memory bus speed on my dell optiplex 170l? The CPU is an Intel Celeron 2.4GHz. The mother board processor speed is 400MHz and the Bios indicates a memory bus speed of 266MHz and does not seem to have an adjustable option. If the CPU can run at 400MHz then why can't I get the memory bus to run at 400MHz? Origanuly this system was shipped with 2 X 128MB 333MHz DDR CL2.5 Non-ECC DIMM modules and yet the bios indicates memory speed at 266MHz.
