[3.处理器设置之Core i7 920]

本次测试的三个平台均采用HD 5870单卡以及双卡两种模式，所选CPU也会在三种不同的频率下进行测试，系统其它配置则尽量保持不变。其中四核心的i7 920默认核心频率为2.67GHz，另外还会分别超频至3.4GHz和4.1GHz（所用平台能够达到的最高频率）进行测试。下面是i7 920具体频率配置信息：

Core i7 920 @ 2.67GHz

Core i7 920 @ 3.4GHz

Core i7 920 @ 4.1GHz

实际测试中，我们打开了ASUS P6T Deluxe主板的Load Line Calibration功能，并根据处理器核心频率的不同将默认电压由1.2V调高至1.3825V。系统内存（DDR 3）频率方面，前两个测试选项设定为1.6GHz，第三个设定为1.56GHz，电压为1.64V。这样以来，内存工作频率基本保持一致，延时统一设置为7-7-7-14_1T，以尽可能地保持相同的读写速度以及存取时间。至于系统其它超频参数则采用主板BIOS默认设置（设置为Auto）。
