CPU Multiplier Incorrect

So I installed a new 2.4 Ghz Pentium 4 CPU today and adjusted the FSB to 133 accordingly in the BIOS. When I boot up, it says the multiplier is 12 instead of the 18 to make the CPU run at 2.4 ghz, so right now it runs at 1.6 Ghz instead. I've tried resetting the CMOS, taking the battery out for a few minutes and then putting it back in, and tried taking out the unpaired RAM, but nothing seems to work. I also can't adjust the multiplier manually, so I am at a loss as to what to do. My current specs are the following, also don't know if the CPU type matters.

I'm afraid you might have a compatability issue there. Your CPU is a Pentium 4M(Mobile processor) 2.4. What's likely happening, is either your motherboard is having troubles properly recognizing it, or it's reading the Speedstep multiplier. Try booting into your OS. Download and run this program.

If it's Speedstep related, than your processor should speed up to 2.4GHz(18 multiplier) when in use, and slow down to 1.6GHz(12 multipler) when idle. That's to save battery life, as it's a mobile(laptop) CPU. If it never speeds up to 2.4, then your probably out of luck, and have to stick with 1.6GHz, as it's more a BIOS issue with the mobile CPU.

Ah ok thanks, I was sorta thinking it might be that.
