Quote from Tight Face:
Not true at all. Intel would never intentionally design their chips to be overclocked.
Silicon based chips are always designed on the wafer to reach their peak performance potential (think the extreme chips). But for the most part, the chips are unable to sustain stable performance at those clock speeds. So instead of tossing the chips, Intel just lowers the clock speed and rebrands it as a new SKU.
This also applies to n-core chips in the future. Some cores don't may be problematic, so Intel will just turn off one or more of the cores and rebrand it. Think of an 8-core chip selling as a 6-core chip.
Semi's are already doing this in the embedded systems world. I was confused when freescale sent us some prototype dual core ARM's but only one core showed up in the bootROM. There response was, they forgot to change the SKU silk screen. And sure enough, they eventually did. Their single cores are actually dual cores, with one core disabled due to performance quality.
The MOBO makers on the other hand have everything to gain by including clock changing settings in their products.
Most people mistaken OC as simply increasing the clock speed on the silicone.
There are many articles on the web about the Q66 and OC. Whoever interested can Google for them.
