OC rebooting the system

[Slay3r]

I have been trying to oc my Athlon XP 2600+ from its current 1921Mhz to 2Ghz +

I have tryed the following.

175 x 11.5 (default multi) - system rebooted after going into windows and playing the windows sound.

175 x 11.5 vcore @ 1.70 - system rebooted again but as it came to the login window.

Any idea why the system keeps rebooting ?

Also i did a post earlyer and someone said to set the multi to x12 also did a post on another forum and i was told there to set the multi to x12.5 and leave the FSB.

Try 1.75-1.8v on the cpu.... If that doesn't do it try upping the memory voltage to the next setting (if your trying the FSB method). You could also try setting the cpu multiplier to eleven to make sure it can be adjusted.

very highly doubt its ur CPU as the voltage is already up. In fact it should be able to do 2ghz default vcore maybe more. Try upping ur ram voltage :toast:

Tryed it at 175 x 10.5 since i 1st posted this and the same thing happend but 1 thing was diferent.

As it went into windows a window poped up saying.

Protection Error

more volts, if more volts doesnt cure it then it's a bad mobo. Sorry guy but that is a bad mobo symptom.

[Slay3r]

How much more you mean by more volts ?

Might try some nb cooling but it might be down to the CPU speed the mobo can take but would 80-100 Mhz cause that much of a problem ??

KT400...

It may not have a divider past 166mhz, and is probably what's causing you problems (high AGP/PCI bus).

If your chip is unlocked, lower the multiplier. If it still does it, its your board.

If you have a divider at 200, you should just skip right to it.

I'm not too knowledgeable on those Via's.

So just leave the FSB and lower the multi to say 11-10.5 and see if it still reboots?
