核心1GHz：蓝宝毒药版5970 4GB超频再测试

Radeon HD 5970是地球上最快的显卡，蓝宝的毒药版又凭借更高的频率和更大的显存提升了12.3％，那么再继续超频又会如何呢？

Radeon HD 5970的默认核心/显存频率仅为725/4000MHz，蓝宝毒药版预超到了900/4800MHz，已经分别提高了24％和20％。

由于三风扇四热管的散热器效果很好，所以我们使用微星超频工具AfterBurner将核心电压加高到1.3V(确定后显示为1.299V)，此时可将核心频率最高提至1000MHz，4GB GDDR5显存频率的极限则是5036MHz(实际工作频率1259MHz)，再增加1MHz也会导致系统死机。

这样，我们又额外获得了11％和5％的频率，性能可以受益多少呢？温度、噪音、功耗是否会大幅增加？
