Core i7系列近期最值得关注的热点莫过于D0步进的出炉。根据此前测试，新版Core i7-920可以在不太高的电压下达到4.4GHz，尚未发布的新高端Core i7-975 Extreme也更好地控制了功耗和温度。今天，日本超频玩家PcCI2iminal和Yoko又利用D0 Core i7-975的工程样品，在风冷条件下突破了5GHz大关。

超频平台配置：

主板：映泰TPower X58 (BIOS 0406) 散热器：Thermalright Ultra 120 RT 风扇：San Ace (102CFM) 内存：海盗船Dominator DDR3-1866 2GB×3 显卡：迪兰恒进Radeon HD 4890 硬盘：创见32GB SSD 电源：Topower GIGA-EZ 1000W 室温：20℃

Core i7-975 Extreme默认频率3.33GHz(133MHz×25)，在超频过程中经过3.6GHz(133MHz×27)、4.6GHz(200MHz×23)、4.75GHz(190MHz×25)等试验后最终稳定达到5015.48MHz，此时外频185.75MHz、倍频27x、QPI总线频率3343.4MHz，而且期间始终都是开启全部四个核心的，没有刻意屏蔽。

5.0GHz下没有进行性能测试，不过4.6GHz下八个虚拟核心在CinBench R10 x86里跑出21818分，4.75GHz下SuperPI 1M只需8.672秒，同时CPUMark得到740分。
