Re: "The End of overclocking coming soon."

Jim, I know this guy has to post "the company line" so I can understand but his claims don't hold water. First I don't believe reliability is an issue in overclocking unless someone overclocks above the highest available speed bin. The design rules for a given process encompass reliability concerns. A 450mhz part is from the same mask set and process flow that a 350mhz part is (in most cases) and differs only in the planetary alignment and phase of the moon when it was going through the fab. This holds true for AMD as well as Intel. The fact is there is a speed distribution across a given process. Not all parts run at the highest speed and not all run at the lowest. This post fails to address the question of what to do if you have 5% binsplit to the lowspeed bins and 10% demand. The practice is to use parts from a higher speed bin and label them as the lower speed bin. It's better than not filling the orders. This is not restricted to Intel but is common throughout the industry. Therefore the lower speed parts MAY be overclockable but you don't know if your part is one of the 5% that binned slow or one of the 5%higher speed parts. You takes your chances. What may be happening here is that Intel may have no binsplit to the lower speeds at all, so they must clocklock their parts to have any low price offering.

BTW: the percentages mentioned were purely for example. I have no real idea what Intel's binsplits are for their processors.
