Hi, About 2 months ago i overclocked my Amd Athlon Xp 1800+ to 2400+. i crashed and when i turned on my computer nothing would apear on the screen. I reset my cmos on the motherboard and waited about an hour. it turned back on and everything is working. Can it fry

It can fry if you have not enabled any Shutdown Temperature in your BIOS. Some BIOSes set it by default to some temperature, while some have it disabled by default.

Enable this safe shutdown feature for 70 or 75 C (depending on what options your BIOS gives you). It is also handy to enable a warning temperature so that you know when the CPU is heating up. I set this at 65C for my (now dead) Athlon 2000+ which I had moderately overclocked to 2200+.

But in most cases, the comp will start hanging well before it reaches a temperature where it can fry. If your 1800 is working now, then not to worry.

Depending on the core, the 1800's clock is ~1.5Ghz. A 2400 is clocked at 2.0Ghz and that means you have done a 33% overclock which is HUGE. Either your mobo or your RAM have not been able to handle this speed and hence your system hung.

Tell us which motherboard you are using and also just how you did the overclock. Then it would be possible to tell you just how to go about the overclock.

Fried PSU => my 2000+ XP, mobo, mouse and 9600XT are also fied. Damn those light-weight high wattage PSUs!

My mobo is very old. Its a Gigabyte Ga-7vkml

I overclocked by setting a fsb jumper the highest and then in the bios.

yes, what you have done is an overclock, but as you probably have realised by now, there is a LOT more to ovrclocking than just this!

I strongly suggest that you do research on this before making any more attempts. Look at this forum itself - a good starting place. Or just google for 'overclocking basics'.

On first look, your board does not seem to offer overclock options. Just what options did you find in your BIOS?

oh, do read some threads on this forum to know what to do and what not to do!

Well in my bios there is a Cpu Clock frequencies and i set it up to 170 mhz to get the 2400= it is on 133 now becuase i dont want a too big risk in overclocking.

It's not gonna fry if it can't run. All you did was over-overclock your CPU & it wouldn't bot up. You didn't damage anything...the only way that would happen would be if the overclocking caused the CPU to overheat & you didn't have the shutdown/warning feature enabled as Kailas mentioned & you just let it keep on running.

If what you did was jump directly from 133MHz to 170MHz instead of overclocking in small 5MHz steps, what happened was to be expected. You have to compensate with your voltages, your RAM settings, PCI/AGP bus settings, disable Spread Spectrum, etc. It's not as simple as just increasing the FSB & you're done. I suggest you read up on how to properly overclock before you really do fry something.
