Automatic RAM overclock, by NVidia

You may be surprised to learn that on most PCs - but not on Mac - it is quite easy to overclock the RAM, by tuning either the frequency or the timings.
NVidia wants to have that process automated on mainboards using its chipsets, provided that it also uses compatible RAM.
Every single RAM module comes with a small EEPROM chip allowing the computer to recognize it and use it accordingly with its specifications. Currently it is only about base information such as the available frequency/timing couples. Corsair will be the first to sell modules with EEPROMs providing more in-depth data, most importantly the maximum frequencies.
Taking into account the other components' tolerance threshold, the chipset will then automatically overclock the RAM.
