怎么使用显卡为boinc工作？

myboinc

我的电脑上安装了显卡，但是从消息上看似乎没有参加到计算中。请问应该如何设置才能使用显卡呢？（我的显卡是NVIDIA GeForce 9600 GT,操作系统Microsoft Windows XP: Professional x86 Edition, Service Pack 3, (05.01.2600.00),参加的项目有World Community Grid、SETI@home、Milkyway@home）以下是boinc上的消息：

这个问题我看了教程和指南，也用在网上搜索过都没有找到解决的方法，麻烦各位高手耐心帮我看一下，帮我把GPU用起来，谢谢各位了！

Tynox

从这份日志看貌似没发现显卡。

ledled

是不是安装在服务模式下了？安装在服务模式不能识别显卡的。。

myboinc

ledled你好，我重新安装过程序了，确认没有安装在服务模式下。我为了方便管理两个安装文件夹都放在了Program Files文件夹下面了，不知道这会不会造成对显卡使用的影响…
Tynox,我的电脑是有显卡的啊，就是我说的型号，就是不知道为什么在boinc上不工作。
谢谢你们给我的帮助！

    是不是装了最新驱动，如果是的话请还原至196.21 WHQL驱动
    http://www.cnbeta.com/articles/105646.htm

cuihao

XP服务模式也是可以识别显卡的。

看看驱动版本。

myboinc

我的显卡在更新了驱动程序后终于为boinc开始工作了，其实我并不是安装了最新驱动，而是从买电脑到现在没有更新过驱动，版本过低所致
    谢谢ledled、chihao和Wayne_Chang给我提供的帮助，特别感谢ledled给我提供的下载链接！
   如果哪位高手有空，请帮我看一下下面的消息吧，帮我确认一下GPU是不是真的已经开始工作了，谢谢了！

    我的任务原来只有五六个的，在安装了新的显卡驱动以后突然增加到上百个，这样是正常的吗？另外，在接下来的消息中，还一直出现一段相同的红色消息，好像是仍然有什么地方不对，麻烦知道的高手能给我一些指导。消息如下：

    最后，再一次感谢所有帮助我和关心过这篇求助的人，我会和大家一起努力，一起为我们中国的分布式计算做贡献！

myboinc

请问这里指的双精度是硬件决定的还是软件决定的呢？如果是软件决定那我希望把我的显卡调成双精度的，充分利用。（我知道这个问题很弱智，我尝试了用搜索引擎查找这个问题，但是结果都是有关编程方面的答案。请大家不吝时间告诉我一下吧，谢谢了！）

    抱歉，当然是硬件决定的

嗯。显卡性能限制虽然有点失望，不过我还是会和大家一起努力一起推广分布式计算，一起为科学事业做贡献的！谢谢ledled！

再次肯定~96GT还不如96GSO!

总觉得自己的显卡（NVIDIA GeForce 9600 GT）不怎么支持BOINC的计算，后来干脆跑FAH去了，现在我的CPU跑WCG，GPU跑FAH，温度都是50来度的说~~FAH跑了半个多月，分数首破4万，在3213里的排名进400了

不是你的显卡不怎么支持 BOINC，而是刚好被你碰到需要双精度运算功能的项目。。

这里有列出来所有支持显卡计算的项目：http://www.equn.com/wiki/GPU#NVIDIA.E6.98.BE.E5.8D.A1
参考一下吧。。
