When a Microprosser is first built they test it at different clock speeds. The manufacturer will take maybe 100 of them and run them through the paces testing different clock speeds. They then find at what speed they perform with minimal heat and maxium speed. Lets say a processor will run at a mim temp ai 1.0 Ghz
and will run hot at 1.5 Ghz they then add a heat sink to see if it will bring the temp back down to the normal running temp. Then they speed it up again and again adding larger heat sinks and fans until it gets to the burn out point where they can no longer keep it cool by reasonable means lets say 2.4Ghz they then check all the test results and see at what speed and at what temp the Processor worked the longest and the best lets say 1.85Ghz now the manufacturer doesn't want their product to fail once the consumer has it so they will down grade it and then clock it at 1.7GHz and sell that micro-processor as a Pent 4/1.7Ghz microprocessor. so when someone like you or I over-clock it and put a larger heat sink and fan on it to try to get 2.2Ghz out of it and it burns out the only one to blame is you, so be very careful when over clocking and if you don't know what your doing then don't try it because you could smoke the whole motherboard and we don't want to see you cry.
