Introduction,
If you have an RTX 4090 in your system you will see a new tab in Nvidia Control Panel, Change ECC State. Additionally this option is available on all newer Quadro(RTX) and Tesla cards
ECC is Error Correcting Code. On GPUs it is a feature that uses extra memory bits to store error information, for certain use cases if an error of particular severity occurs it can either be detected and/or corrected.
ECC is not useful for GPU rendering, we recommend turning it off for all your GPUs as it degrades performance. In our tests, turning on ECC reduced performance by 15% on the RTX 4090 and Tesla A40 GPUs while making no difference on GPU rendering.
Note, ECC is off by default for Geforce and Quadro(RTX) cards, but for Tesla cards it is turned on by default(we recommend turning it off)
Turning off ECC state requires a system restart
Best,
Muhammed
