對換位置試試看 第九篇回覆中那個測試中 測試人員也是讓2900當主卡 3870做副卡
"...Before we gave up on this idea we decided to have one last attempt and switched round the cards so that the 2900 XT was the primary and the 3870 was the secondary. Once again both cards were recognised by Windows and once again the ATI installer reported success on driver install. We rebooted and to our surprise device manager reported both cards as working."
