Laptop CPU in a desktop?

There are no "PPGA" processors. While PPGA is still used, it's called FC-PGA (Flip Chip-PGA) when the die sticks out of the top of the pin grid. FC-PGA has been around since the first Socket 370 PIII's. All Intel processors are now FC-PGA. FC-PGA2 refers to an FC-PGA processor with a heat spreader. ALL P4s are FC-PGA2. PIII's have been FC-PGA2 for several years. Celerons are FC-PGA2 and have been since the introduction of the Tualatin. The only mainstream processor Intel makes that isn't FC-PGA2 is the Pentium M. And even the Pentium M is FC-PGA.

It will work. Just as any normal desktop CPU would? That's hard to say. Most P4 laptops use desktop CPUs. If it's a desktop CPU from a laptop, it will work like a desktop CPU. If it's a P4-M, it will still work, but drop the multiplier to the lower one by default.

Does your IC7 allow you to adjust the multiplier?
