Hello, Looking to put a faster CPU in my Dell notebook. Current chip is an Intel T2300, 1.66Ghz clock speed. System bus is 667 and bus/core ratio is 10. Would replace with a T2600 with a 2.16Ghz clock speed. The T2600 also uses 667 system bus but has a bus/core ratio of 13. Compared them on the Intel site and all other parameters (voltage range, socket etc.) are the same for both chips. QUESTION: Will this difference be critical to allowing this replacement CPU to run? And, will using a CPU with a different bus/core ratio require a change to BIOS settings?
