Advice for a novice OC'er on P4 1.8A Overclock

All,

Was hoping this forum could lend me a hand on this I'm trying to get stable at 2.4Ghz (133 Bus) and having a little bit of difficulty.

CPU: P4 1.8A (SL63X, Philippines, 6/10/2002)
Cooling: Retail heat sink/fan with thermal paste
M/B: Giga-byte GA-81G 845G board (A friend had good experience with Gigabyte boards and OC'ing, unfortunately he's on vacation right now)
RAM: 2 512MB sticks of Corsair XMS DDR 333

If I set the bus to 133, I can load Win XP at 2.4Ghz and do low level things like web surf, email, etc. But if I try to run something more system intensive (Everquest is what I've tried mostly, but other games show the same), it hangs up andI have to reset.

Because Windows boots, I'm thinking that I only need a minor tweak to get to fully stable. WOuld upping hte voltage a little be enough? Or would I need to tweak the cooling more too?

Thanks in advance,
Bart
 
Yes,you need to up your voltage.Only up it one notch at a time and play some games for a couple hours and see how stable it is.If still unstable go one more notch and so forth on the voltage.A lot of guys here use Prime95 and let it run all night to see how stable your running.Some will run it for an hour just for testing and then try for higher FSB until unstable and then add more voltage.Once you find a setting you like or the best O\C you can get you should run Prime95 overnight to make sure your stable.Your only on default voltage so you can squeeze more out of it.I wouldn't recommend personally going over 1.7 volts though.Here is the link for Prime95 aswell as other downloads.I wouldn't recommend topping out the CPU with the retail heatsink and fan.If your using the stock thermal pad that comes with it could be bad news.Get some arctic Silver 2 or 3 and a better HS and fan.With a good HS you won't need a high speed noisy fan.A low 21dba 27cfm fan will work great and be quite. Prime95 and More
