GTX 480 driver 问题: driver 和runtime version may be mismatched

windows server 2008, devdriver_3.2_winvista-win7_64_260.61_general, cudatoolkit_3.2.12_win_64,gpucomputingsdk_3.2.12_win_64

跑devicequery 和 bandwidthtest 的结果如下,说是driver 和runtime version may be mismatched. 所有的换成3.1 也试过, 都不行, 3.0 的driver 装不了, 请高手指教
