No it's not 333MHz, it's actually a 166 'MHz' FSB processor....333 is just
AMD hype to sell the virtues of the DDR bus. Intel do the same trick but
they multiply the real bus speed by 4x.

Double and quad pumping the bus is not "hype." It's an engineering
technique for transferring data twice, or 4 times for quad, per clock cycle.

333 is the bus cycle rate, e.g. "Bus Speed," and is the relevant number
from a performance standpoint.


The maximum that the processor will run at depends on many things. If it's
un-locked you would be able to lower the multiplier and run it on a 200MHz
FSB, however if its one of the more recent locked models the maximum FSB
would be in the region of 175-190MHz, depending on how overclockable the cpu
is, how good your cooling is etc.


He didn't ask what speed he might be able to push it to. He asked "What is
the maximum that the Athlon XP 2800+ supports?" and the "Maximum System Bus
Speed" that the processor "supports" is the bus speed it's rated for.
