Default FSB and RAM speed

sponsored links

Should my RAM speed by the same in MHz as the FSB speed? Could i use DDR SDRAM 400 MHz on an VIA KT400 chipset with an Athlon XP 333 MHz FSB? Is the VIA KT400 chipset have the capability of operating at 400 MHz FSB, but the Athlon XP can only go to 333 MHz FSB, so the VIA KT400 chipset is made only to be able to take advantage of 400 MHz FSB when the Athlon XP in the future supports that FSB speed of 400 MHz? So for now, the VIA KT333 chipset would perform just as well as the VIA KT400 chipset with the same CPU and RAM?

all KT400 mobo's i've worked with allow you to set the CPU FSB 100/133/166 and MEMORY BUS 133/166/200

You will be able to run the FSB at 166/333MHz and the memory bus at 200/400 but you will gain little by doing that it's better to keep the FSB and the memory bus the same and if you 400MHz ram you will be underclocking it but you will be able to run really fast memory timings which will give a increase in performance and also it will give you some head room if you plan on overclocking your cpu.
