The Change ECC State page lets you:
Change the Error Correction Code (ECC) state for GPUs.
View GPU memory details.
This table shows the ECC state for each GPU that supports ECC.
GPU Column: Shows the GPUs in the system, and also indicates whether they are part of a Quadro Plex system or part of an SLI group.
ECC Column: Check boxes appear for GPUs that support ECC, and show the ECC state.
SLI or Multi-GPU groups can have a check box, which serves as the master control for all the GPUs within the group. In other words, all GPUs within an SLI or Multi-GPU group must bet set to the same ECC state.
Grayed-out boxes indicate ECC states that cannot be changed because either the GPU itself cannot have ECC disabled, or the GPU is part of an SLI group.
Under Windows XP, this section shows the amount of dedicated video memory.
Under Windows Vista and later, this section shows the total available graphics memory, the dedicated video memory, the system video memory, and the shared system memory.
