What it's actually running at. My 3000+ is rated at 13x166,
2166Mhz. I run it at 13x173, 2250 Mhz EG,
model name : AMD Athlon(TM) XP 3000+
stepping : 0
cpu MHz : 2250.146

2008/133 = 15
Better boards have a jumper to set FSB, then bios tweaks to
modify that in 1 or 2 MHz increments (o'clocking capable boards).
266 FSB is mostly a marketing gimick. The actual FSB frequency is
133. DDR uses the rising and falling parts of the sine wav signal
to 'double' the bus. It doesn't. It gives about a 5 to 7%
increase in performance over non-DDR.
Your multiplier and FSB settings in bios is correct for your
cpu. Many boards that don't have high multipliers, further
multiply lower settings. EG, your board probly uses a 5 setting,
multiplied by 3, or a 7.5 multiplied by 2.
BTW, Jetway is one of the dozen or so brand names PC Chips
boards are sold under. PC Chips often makes the same model
board, but uses different chips and bioses on them. So whatever
manual you find for that board, might not match it exactly.
