Help with frontside bus!

[ttrimmer]

I admit to being new to building a system. I have used computers for as long as I can remember, but have never built my own system. I am confused about frontside bus settings in bios. I came here because this seems to be the best computer forum on the net.

I am building an Athlon XP 2200+ system. I am not going to overclock this. I bought a Soyo Dragon Ultra Platinum motherboard. It gives the option of setting the frontside bus to 100 or 133Mhz depending on the processor. The Athlon 2200 has a bus speed of 266Mhz (that's what I read somewhere anyways). What would I set the bios to? The default is 100 Mhz. There is no 266Mhz setting. Also, the board supports PC1600, 2100, and 2700 DDR ram. The instruction book says you can set the speed for the ram to 100, 133, or 166Mhz depending on the memory. I was thinking about the 2100. Would that be set for 133Mhz and does this have any effect on what the cpu frontside bus is set to?

Thanks

Set it to 133mhz.

Welcome to the Forums

The Athlon's FSB sends data twice on each clock cycle in the DDR fashion. The 133MHz clock rate setting corresponds to an effective FSB of 266MHz.

Set the board to 133.

So if that is true is it better to get the 2100 ram that runs at 133Mhz also??? Thanks for all the help.
