X1800XT问世还没几天，针对X1800XT的折磨行动已经开始，DriverHeaven宣称已经将X1800XT提升到685/1790的目前世界最高纪录。呵呵，开玩笑了，DriverHeaven网站只是在默认散热条件下对X1800XT进行了一项超频测试，简单测试一下X1800XT是否还有频率提升空间。不过相信以后随着X1800XT的大规模出货，全球的超频狂人们肯定会很快刷新DriverHeaven这一纪录的。下面我们不妨一起来看看DriverHeaven的测试过程：

测试软件和平台:

AMD Athlon64 FX55 CPU

2x512mb DDR 3200 (2-2-2-5)

Samsung 80Gb 7200rpm 8mb Cache Sata Drive

Sony DWD22a DVDRW drive

Ultra Xconnect 500w PSU

ATI Reference Crossfire Motherboard

Windows XP SP2

.Net FW 1.1 sp1

Catalyst WHQL (X1800XT专用版驱动)

Doom3

X1800XT的极限超频测试

大家都知道X1800XT的默认频率为625/1500，DH首先把目标锁定在了650/1600，650/1610频率下表现完美，没有任何图形方面不正常的现象出现，所以下一步的目标就是678/1700。

678/1700频率下连续运行了几边3Dmark和Doom3都很正常，看来这一频率对X1800XT不是什么难事，所以DH的测试人员又把目标提升到了700/1700。不过遗憾的是700/1700频率下因为VPU recover测试退出了，看来X1800XT的核心频率在默认散热条件下的极限很难超过700了，最终经过几次尝试，DH的测试人员把频率稳定在了685/1790。

超频的最终目的肯定是为了性能提升，我们看看了超频的X1800XT性能提升如何？
