I Have an older Compaq Presario 6410NX with a FIC AM-37 mobo. It has Phoenix Award BIOS core v6.00PG, BIOS rev. 3.08, date 12/16/2002. It currently has an AMD Athlon XP 2000+ Palomino CPU, 266 FSB. I would like to replace it with an AMD Athlon XP 2400+ Thoroughbred CPU, 266 FSB for possibly added speed. Can anyone foresee any advantages or problems in doing so and will I have to update the BIOS? Any recommendations would be greatly appreciated.
