Question 10
UnclassifiedWhat does 'ECC Mode: Enabled' in nvidia-smi indicate?
Correct answer: B
Explanation
“ECC Mode: Enabled” means the GPU’s Error Correcting Code memory feature is turned on. ECC memory “detect[s] and correct[s] memory errors,” which helps protect data integrity during GPU operations.
Why each option is right or wrong
A. Extra Compute Capability is enabled
B. Error Correcting Code memory is active, detecting and correcting memory errors
In NVIDIA’s GPU status output, the ECC field refers to Error Correcting Code support on the device, and an “Enabled” state means that the memory protection mechanism is turned on rather than merely available. On supported Tesla/Quadro-class GPUs, ECC uses extra check bits to detect and correct single-bit memory errors and detect multi-bit errors, which is why the status indicates active memory error protection during operation.
C. Enhanced Cooling Control is active
D. External Clock Control is enabled
