Windows XP won't recognise Intel Core2 Duo E4600 2.4GHz dual-core processor's second core, but Windows Vista does

This problem often occurs after switching from a single-core processor to a dual-core processor without reinstalling Windows XP. You replaced the motherboard and processor, but used the samehard disk drive with Windows XP Pro SP3 installed on it.

Note that if you have an OEM copy of Windows XP/Vista and you change the motherboard, you have to buy a new OEM copy of XP/Vista or a new licence, because an OEM copy can only be installed on one computer, and changing the motherboard is defined by Microsoft as changing the computer. You are only allowed to change the motherboard if you have to replace the existing motherboard with another motherboard of exactly the same make/model.

Why is processor running so hot during a video conversion?

The computer would have shut down if it were actually running that hot, so I would say that the temperatures are an illusion.

You can use RMClock, as it has a display that shows the state of "throttling". If the processor's temperature goes over about 70C, the processor reduces its processing rate for short periods to control the temperature, which you would see that in the RMClock graph.

So if you don't see throttling, then you know the real processor temperature is not 118C. What you want in a hardware setup is to not lose any performance. So, if you see the graph dip when AGK runs, then you need more cooling, or to clean, apply paste, and reseat the processor's heatsink and fan cooler.

Failure with the processor

There are many possible reasons why a processor can appear to have failed. In the real world, outright processor failures are very rare, especially if the processor has worked in the past (unless we are talking about a very old CPU, more than ten years of age). If the processor works for the first month that it is installed, it will probably last for five or more years, as long as it isn't abused. Problems with processors are far more likely to be misconfigurations, overheating problems, or misdiagnoses of other failed components.

Unlocking a CPU/processor locked cores

Perhaps  many  of  you  reading  this  have  also  read  that  the AMD  Phenom  II  X2  550  Black Edition dual-core CPU/processors have two locked cores. Mine has and I unlocked them to make it a  quad-core  AMD  Phenom  II  x4  processor.  Luck  is  involved  and  I  will  explain  why. When AMD manufactures  its  Phenom  CPUs/processors,  they  are  all  made  quad-core  (not including the new hexa-core (six-cores) models. These four cores are tested to make sure they work as they should. If that is the case, they are sold as quad-core processors.
