overheating protection

[t4h]

How well does the overheating protection for P4 1.4GHz work? If I would test around a little with the FSB, making the clock-frequency to high for my crappy heatsink, would the processor turn off before it would take any damage?

And a second question, If I raise the FSB from 100MHz to 112MHz would that in any way interfer with the AGP and/or PCI slots? please explain...

100Mhz to 112Mhz should still be stable as far as the accessories go, but some are rediculously sensitive.
Your system will become unstable far before you'll do any processor damage, you're thermal sensor and thermal protection probably won't even come into the equation.
Now, that being said, when your system is unstable, you can bump up the voltage a little, nothing rediculous, to make it more stable, but you run the risk of long term damage if your cooling isn't up to par. your thermal shutoff won't cut it off or slow it down until it gets very hot, somewhere past 70*C if I remember right.

Alright, that sounds great...

But as for my second question, would I be doing something funny to the AGP and/or PCI slots by raising the FSB to 112MHz?

the pci and agp clocks would rise... to around 37mhz for pci and 75mhz for agp...

if in doubt blame microsoft...

yes, you will be overclocking your AGP and PCI bus some, but going from 100 to 112 usually causes no problems.
Some ATI cards may not like it.
your PCI bus should be about 37Mhz, your AGP would be near 74Mhz.
There may be a setting that will allow you to reduce the AGP and PCI speeds, but I don't know, I've not had good motherboards that allow it.
If you can hit 133Mhz, it should drop your AGP and PCI back to stock speeds.

Wonderful, now I only got oe more question:

What about voltage? If I change the FSB, should I also change the core voltage? If yes, how much should I increase/decrease it?

first wait and see if it is unstable if it is then raise the voltage

But what would happen if I would enable too much voltage, would I damage the components?

i don't think your baord ill really let you put to much voltage to any the voltage increase the heat that is one of the side a ffects

in other word mabye its time to get a new cooler

Just thinking about what someone said earlier about 133MHz bus. How unstable would that become?

I would underclock the memory in compairson to 112MHz FSB by 98MHz, but I believe a CPU clock-frequency of 1862MHz as well as factory-clocked AGP and PCI slots are worth it. Now, do you guys believe such a thing would be stable?

if you can get it to a 133Mhz bus, you can set all of your other specs back to normal specs, memory bus to 100Mhz, AGP to 66, PCI to 33.
you may be able to do that, all rests on your processor.
btw, I still hold that you're AGP and PCI buses can handle that modest overclock, my laptop was running an 80ishMhz AGP and 40Mhz PCI.
74 and 37 aren't that far off.

Hmm, alright, I think I'll settle for the 112MHz FSB after all, plus I won't have to invest in a brand new cooler
