cudaMalloc crashing on win7 GTX680, CUDA3.2

Hello,guys,I got a problem on cudaMalloc on win7.
hardware is gtx680, sdk is cuda v3.2.

I compile and run the same code both on windows server2003 and win7.
The former runs well. But to the latter, it will crash when i call cudaMalloc.

The attachment is the testing code i download from other site. (31.4 KB)
