It won't work. PII-233, 266, 300, 333 all have bus speed of 66MHz. Multiplier is locked by the CPU at 3.5, 4.0, 4.5, 5.0. I am not clear what the jumpers are for. Change them at your own risk.
Newer motherboards achieve overclocking by changing the bus speed. This can cause other problems because memory is tied to the bus speed, as in PC100 for 100MHz bus. PC66 for 66 MHz bus.
