PC2100 w/ 333 MHz Barton and Soyo KT600 Ultra PE

I'm building a system using:

Soyo SY-KT600 Ultra Platinum Edition Motherboard
Athlon XP 2500+ Barton
PC2100 sticks of several sizes and makes

The CPU's FSB rating is 333 MHz. Does that mean I can also run it at
266 MHz so as to synchronize it with the PC2100 memory?

I know the memory is not well suited to the CPU, but I just want to run
everything according to spec, safe and sane, without much tweaking.

The BIOS offers these settings for "CPU Freqency Mode":
Auto, Manual, 100, 120, 133, 140, 150, 166, 200.

The FSB can be set from 100 to 255 in 1 MHz increments.

The DRAM clock can be 100, 133, 166, 200, or by SPD.

The CPU multiplier can be set from 5 to 17 using DIP switches.

Would it work to just set the CPU frequency and the FSB and the DRAM
clock to 133?

How should I set the multiplier?

Ummmmmm . . . OH, boy, where to start.

Most modern chipsets can support asynchronous memory speed settings. That
is, the CPU clock (before multiplier) can be different from the speed the
memory is running at. If the CPU clock and RAM are the same, your system
will be very slightly faster, but you will only notice if you run some kind
of benchmark on it. That is to say, there will be no noticeable
differencek, and the NUMERICAL difference will be tiny. And while
underclocking your CPU would not cause much of a noticeable difference,
either, there is no GOOD reason to underclock your CPU. The underclocked
CPU is going to slow your system down more than matching CPU and RAM speed
will "speed it up". You'll have a net LOSS of system performance caused by
(ironically) your attempt to speed things up a bit.

My suggestion . . . run your CPU and RAM at default settings, or set your
BIOS to "auto". -Dave<!-- ~MESSAGE_AFTER~ -->
