I was looking around for some tech reviews, and saw these articles on the Core i7(this shit is kinda long by the way);

In previous reports, we learned that first revision of the boards had these two things Vcore and Vmem synchronous. We learned that motherboard manufacturers will be able to separate the CPU and memory voltages, and yes, this means that you will be able to set the voltage on your CPU independently from the one on your memory. This will certainly make the overclocking much easier, as you won’t burn your CPU with 1.8V voltages that you might need for some ultra faster DDR3 memories. You can expect that the next Asus, MSI, Gigabyte boards, among the others, comes with separate Vmem and Vcore settings. -[/url]

Of course, for such a task you need a great motherboard. Furthermore, if you want to go over 5GHz and even 5.2 to 5.3GHz you need to play with LN2 but apparently this is possible and it has been done with demo CPUs. These are some of the numbers you should be reaching once the CPU is out. Naturally, the Core i7 Extreme edition at 3.2GHz and overvoltage protection removed should be able to reach the highest clocks. It is safe to say that whatever speeds you’we seen on Core 2 Quad 45nm Yorkfield parts, you should be getting with Nehalems or you should at least be within that range. Looks like overclockers will like this one but beware, the memory speeds will suck, especially compared with X48 memory scores.[/url] "

In relative terms, this means that users will be able to push for higher memory frequencies, change memory multipliers and even, adjust the speed of Intel's QPI technology. It is claimed however, that 'overclocking' the QPI speed will only realise small performance benefits, yet the adoption of what is effectively an unlocked memory controller, will give enthusiasts that little more freedom to experiment and attain the best that the Nehalem platform has to offer."[/url]
