A ? About FSB/Memory speeds on i865 mobos
Posted: Thu Oct 30, 2003 7:27 amOK, quick rundown here:
I'm getting an Asus i865 mobo, w/CPU. However, I don't have $ for new memory (yet!), so I have to stick with what I've got: 2 sticks of 266MHz DDR (PC2100). The mobo can run those in dual channel mode for 533Mhz memory speed. Now, that's fine and dandy for a 533Mhz FSB CPU. However, If I get a P4C (800MHz FSB) will I be able to run it with a 3:2 FSB-Memory ratio and still use my current memory? I know my current i845 mobo runs at a 3:2 ratio (400MHz FSB, 266MHz DDR) and the new setup would be exactly 2x as fast on both counts.
So...will this work? Or should I just get the P4B (533Mhz FSB)? I'd really like the C, since it has Hyperthreading and that would be a HUGE performance boost (for me, anyway). Much more so than any clock speed boost...
