NVML does not working with latest driver

Hi, recently i updated my Quadro P400 to the latest driver and the method “nvmlDeviceGetMemoryInfo” inside NVML stopped working (i am getting not supported error) , once i roll back the driver the method is working again. it is a bug with the new driver or is it intended to stop support for latest drivers? , if so is there any alternative way to receive memory use of the graphic card ?
