Overclocking?????

[mbs081200]

Ok everybody, Now I know this has been discussed heavily but please bear with me. I am an overclocking virgin and I'm not sure how to exactly make it happen. I am dealing with an ASUS P4B266 Board and an Intel P4 1.5GHz Processor (Socket 478). I can overclock to 2GHz but whenever I make the change in the CMOS mode to overclock to 2GHz, the system hangs immediately. The only information I'm given is that the board must be on jumper free mode, which it is by default. What else do I need to look at???

K dude good choice for asus they make great boards! first off dont jump all the way to 2 ghz! sounds like your bus is 100 x 15 = 1500mhz you jumped to 133bus x 15multiplier=1995 mhz.
try uping your core voltage 0.15 volts ie 1.50v to 1.65v should be safe keep an eye on your heat. then try 110 bus speed. 1650 mhz keep going from there till you start to crash then try uping the voltage a li'll more, dont over do it and ya might reach a nice speed .What ram are you using? ram is good ram very important I use Samsung pc2700 ddr333 ps make sure your on jumper free mode and manual adjustments in your bios dont use the default choice of 1500 mhz or 2000 mhz . If all else fails Drink loads of beer then when you start to spin everything will seem faster lol!! good luck

The first guy to respond was thinking of voltages for the newer northwood I think. You should try raising your voltage to around 1.85v on this .18 micron CPU. 15x133 is 2GHz, as in 2000MHz, becuase the "33" part of 133 is actually a continuous number, 1/3 of 100, ie 133.333... Yes, at 1.85v it should work. You might get by at a bit less core voltage. I'd go high and test for stability, then work my way down to determine the lowest stable voltage, since 1.85v is safe for .18 micron process cores.
