What causes data corruption...

[CHOPPER GOD]

Anybody know what actaully starts Windows Corruption? (Assuming no 3rd party virus/hack etc)

Is it high FSB running in 1:1?
Why does windows seem to care when you really overclock hard yet if I had the money and bought an fx-55,Im assuming these corruptions wouldn't happen.
It seems with this logic, its not overal clock speed that effects it, but something else...
any ideas? Im at work, sorry for bad grammer but I think most of you get the point..
Thx in advance

The computer will start outputting data that it will not be able to understand. An easy example of this would be overclocking and not being prime stable. It will tell you exactly what numbers should have been reported back by the computers calculations. Prime will error out when the number does not match up. On the same line when you are overclocking too far, the data is basically junk and the computer will reach a point were your applications will crash from the erronous data sets, or you get the old faithful BSoD in Windows at least.

I'm not 100% certain on the mechanics but I'll assume, it has to do with exceeding thermal/frequency limits of the materials within the cpu package. Additional cooling capacity can push this particular value out further than the manufacturer typically sells the product at.

Though someone might be better suited for a more technical answer, my specialty isn't microprocessors.

A very high PCI/AGP freq. is when you typically start to see data corruption..

a PCI bus running in the 40-50 range(33 being stock) and I have seen corrupted HDD's.. However, most boards if not all, now have PCI/AGP locks, so it's not a problem..

thats pretty much it to be fair.

thx guys once again youv'e helped a n00b in under 30 minutes

also, if you have too agressive mem timings, corrupted data can get sent to the hard drive.

Failures related to overclocked are caused by parts producing incorrect results. I.e. the processor adds 2 + 2 and thinks the result is 5. When chips are run faster than they can be reliably run the transistors in them begin to become unreliable and do not always turn off or on when they should, hence the logic errors.

The logic errors lead to windows and/or other programs failing.

When you apply a certain input to the processor, it takes a small amount of time for the electrical signals to propogate through all of the components in a processor. If the clock is faster than the speed of the components in the processor, then the output will be read before it has been completely updated. You might get an old value for the output, you might get the correct value, or you might get something totally random. There is really no way to tell.
