DESCRIPTION: This function resets ECC memory error counters.

SUPPORTED OS: Windows 7 and higher

TCC_SUPPORTED

MCDM_SUPPORTED

\requires Administrator privileges since release 430.39

Parameters

[in]	hPhysicalGpu	A handle identifying the physical GPU for which ECC error information is to be cleared.
[in]	bResetCurrent	Reset the current ECC error counters.
[in]	bResetAggregate	Reset the aggregate ECC error counters.

Returns

This API can return any of the error codes enumerated in NvAPI_Status. If there are return error codes with specific meaning for this API, they are listed below.

Return values

NVAPI_INVALID_USER_PRIVILEGE

- The application will require Administrator privileges to access this API. The application can be elevated to a higher permission level by selecting "Run as Administrator".

NVAPI_INTERFACE NvAPI_GPU_SetECCConfiguration	(	NvPhysicalGpuHandle	hPhysicalGpu,
		NvU8	bEnable,
		NvU8	bEnableImmediately
	)

DESCRIPTION: This function updates the ECC memory configuration setting.

SUPPORTED OS: Windows 7 and higher

TCC_SUPPORTED

MCDM_SUPPORTED

\requires Administrator privileges since release 430.39

Parameters

[in]	hPhysicalGpu	A handle identifying the physical GPU for which to update the ECC configuration setting.
[in]	bEnable	The new ECC configuration setting.
[in]	bEnableImmediately	Request that the new setting take effect immediately.

Returns

This API can return any of the error codes enumerated in NvAPI_Status. If there are return error codes with specific meaning for this API, they are listed below.

Return values

NVAPI_INVALID_CONFIGURATION	- Possibly SLI is enabled. Disable SLI and retry.
NVAPI_INVALID_USER_PRIVILEGE	- The application will require Administrator privileges to access this API. The application can be elevated to a higher permission level by selecting "Run as Administrator".
