I have an old motherboard with 478 chipset, intel Celeron D320 2,4GHz and FSB: 533. My motherboard (2003 year) supports FSB 400/533/800 but now it rus at 533 with celeron. 1. Can I overclock my system to max FSB 800MHz if the rest of the system supports it? My processor runs at 2620MHz and PC3200 RAM runs at effective 366MHz. Original system bus is 133MHz. 2. Can i buy socket 478 pentium processor wich FSB is 800MHz? 3. Wich of these is better: P4 2,8GHz, FSB 800MHz, system bus 200MHz P4 3,0GHz, FSB 533MHz, system bus 133MHz (Or something near that) 4. If processor is 3GHz and FSB 533 will memory bus still be 166MHz? My curren celeron is 2,4GHz with FSB 533MHz and memory bus is at 166MHz. Sorry for bad english and probably posting to the wrong place.
