It seems if you pay up ($35 max), if you fry your -K or -X CPU you can get a replacement for free.

The Performance Tuning Protection Plan being offered by Intel is a chance for you to experiment with the overclocking features of your processor without the worries of what will happen if you push the procesor too far. The Plan allows you a single processor replacement, hassle-free, from our customer support. This is in addtion to your standard 3 year warranty. In other words, if it fails under normal usage, we will replace it under the standard warranty; if it fails while running outside of Intel's specifications, we will replace it under the Performance Tuning Protection Plan.
So what we are saying is this: Go ahead and push it, we've got your back.
It seems they stand by their product and the inherent safety features embedded in the silicon. Push it too hard and it won't break - you will just find its performance peak (lasting at least 3 years).
The RAM bandwidth issue is probably not a practical concern as I haven't seen any RAM frying CPU issues (maybe not booting - due to mobo/RAM). Perhaps they are saying you will fry the motherboard before the CPU?!
My interpretation is similar to this: aluminium baseball bat.
Normal warranty: will hit base balls really well. Replaced if it breaks.
Performance Tuning Protection: hits other things really well. Replaced if it breaks.
I may be wrong and am openly stating this is merely conjecture.
matty, like I said above, I think the problem is that the integrated memory controller on the chip is really not designed to handle the 1.65 volts that a lot of DDR3-1600 and faster RAM needs to operate.
