ok my Via C3 stock 800mhz can easily fly past 1ghz but it has some wierd debugger that locks the system after 5 min so it can only go up to 937 any closer to 1000 and the debugger kicks in. so i was looking at the chip and there are two jumpers on the back side they are both open from the looks of it and have a clear coat on em so since i am hoping someone here has some exp with these things i was hoping that someone would know what those two jumpers control maybe one unlocks the speed and the other makes the fpu run at full speed.

this is a back up chip for my celeT 1399.5, i did an actual clock speed test.

Beer and fragging can never be one.

Ahh what tou are getting is overclock instability. It means you have reached the limit of the overclock. It is not any debugger thing it is just you have gone as far as the CPU will handle. All CPU`s will do pretty much the same when you go too far. They just become unstable and hard lock.

It seems the jumpers you speak of, simply do not exist! Take a look at the <A HREF="http://www.via.com.tw/en/Digital Library/prhome_c3il.jsp" target="_new">VIA C3™ Image Libary</A>, scroll down to find your mentioned processr - which is <b>VIA C3™ 800MHz</b> and from the <i>VIA C3™ 800MHz Still Image Rear View</i> category select <i>High-res</i> (quick-link <A HREF="http://www.via.com.tw/en/images/C3/C3_800MHz_Back_H.zip" target="_new">here</A>).

Now show me, from that high-res image, the jumpers which you speak of. You may wish to double-check that the jumpers are in fact actually on the motherboard.

Perhaps you <i>know what [you are] doing when come to oc'ing generally</i>, however we all make our little mistakes. I am no expert, and I make blinding-obvious mistakes sometimes!

Why don't you give us the brand and model of your motherboard. This information can be obtained in minutes by either checking for screen-print on your motherboard, or using a tool such as <A HREF="http://www.hwinfo.com/" target="_new">HWiNFO32™</A>.

Can I ask why you chose to overclock such a processor BTW? Albeit cheap, what exactly would you succeed in by managing to overclock it? It's hardly going to play graphic-intensive games very well, overclocked or not!

I'm not criticising you for overclocking this particular processor. I <i>was</i> tempted to do so myself, purely because of the cost! So what if I fried it? It's only £27.50 (<A HREF="http://www.dabs.com/products/prod-info.asp?quicklinx=16WS" target="_new">Via C3 800Mhz 64KB</A>). But at the end of day, I knew it wasn't going to be upto much horsework so I scrapped the idea. It was just one those "should I, because I'm bored" ideas whizzing around my head!

Anyway, I hope to get your motherboard brand and model soon!
