A team of computer geeks have set up a PC system equiped with one of the fastest CPUs on the market today - the Core 2 Extreme QX9650 - in order to see the top frequency that can be reached. While the price for such a CPU is around $1300, the benefits are quite obvious when the respective platform will be used for applications which require a very strong processor. The QX9650 was built using the new Yorkfield architecture, which means that it is the first Intel processor to reach the 45nm design process. QX9650 is also the first quad-core processor to sport a 12MB L2 cache while it matches the 3GHz operating frequency of the QX6850. While the 3GHz frequency is rather something "normal" for QX9650, the 45nm building process makes it possible to require 25% less power and to be 26% cooler than QX6850. And that's what made the PC builder team wonder what the frequencies would be this CPU able to reach if overclocked. And, without any water-cooling system they managed to reach 4GHz - and easily too: the CPU was mounted on an ASUS P5E3 Deluxe, with a normal cooler and with the change of 10% in performance increase only! The Bios setting was changed from 9x to 10x CPU multiplier and a change in power consumption - 1.450v. Only on thsese settings did the QX9650 reach the 4GHz but also it was running as hot as QX6850 at 3GHz. The conclusion is that in the case of QX9650, the 4GHz frequency is not a problem and it doesn't require any special cooling.
