cuvidGetDecoderCaps return wrong infomation

Hi Nvidia ,

I am using Video_Codec_SDK_8.2.16 for decoding H265 bitstream.My gpu is GTX 745(Windows 7 SP1).I know the architecture of GTX 745 is Maxwell(GM107-220-A2) and according to the infomation of link,the Maxwell (1st Gen) and Maxwell (2nd Gen) do not support to decode H.265(HEVC) 4:2:0.But when I use api cuvidGetDecoderCaps to get decoder capacity and it tells me the GTX 745 supports to decode H265.In fact when decoding H265 bitstream,the process crashs.Is this a problem? Thanks!
