OK I have a ThinkPad T60p for awhile now, it has Intel T7200 processor in it. I'm thinking to upgrade the processor. The current front side bus speed is 667MHz. But out of curiosity, I was just wondering if it will work if i upgrade to a CPU with 800MHz front side bus speed. Also will it work say if i upgrade to Intel T8xxx series CPU? The motherboard uses Intel 945PM chipset, and the socket type is 479mPGA.
