Phenom II X2 555亦能开核变身X4 B55

“开核”已经成了AMD Phenom II/Athlon II系列处理器最热门的话题之一，刚刚发布的Phenom II X2 555 BE也不出意外地集成了这一“优良传统”。

破解方法还是老一套：找一块配备SB710/SB750南桥芯片的主板，在BIOS里将ACC(高级时钟校准)选项设为自动(Auto)，重启，搞定。

这里使用的是技嘉GA-MA790FXT-UD5P，790FX+SB850芯片组，除了ACC设为自动外还要把“EC Firmware Selection”设为“Hybrid”。

再次进入系统，我们就得到了一颗四核心的“Phenom II X4 B55”，还是商务版型号。

破解之后的四核心运行稳定，而且性能直逼频率高200MHz、价格贵96美元的旗舰级Phenom II X4 965。

处理器	x264 HD 1st Pass	x25 HD 2nd Pass
AMD Phenom II X4 965 3.4GHz	72.1 FPS	22.2 FPS
AMD Phenom II X4 B55 3.2GHz	70.6 FPS	21.1 FPS
AMD Phenom II X2 555 3.2GHz	45.2 FPS	10.9 FPS

不过超频能力受到了明显影响。开核之前不加压能超到3.8GHz，之后只能达到3.6GHz。

顺便再提提Phenom II X4 910e，它的热设计功耗为何只有65W？秘密在于核心电压更低。Phenom II X4 965的热设计功耗为125W，待机和负载核心电压分别为0.992V、1.392V，而X4 910e降低到了0.976V、1.168V。
