Intel Allows More Overclocking Options for Core i7
 

So what can we expect with a Core i7-940/920? Memory will not only running under 800/1066, you can tune up for higher frequency, because Core i7 940/920 now have the ability to change memory multipliers, so mobo maker can write a BIOS with option to increase memory frequency. Also, changes memory multipliers can also allows QPI speed to be changed, but documents pointed out that raise QPI speed will only gain little performance.
