After updating from 1709 to 1803 ,i realize my SLI changed to disabled and i cant enable back.when i applied the SLI option in the nvidia driver the driver showed the applying progress but after it has finished, the SLI selection returned to disable. After this i went back to 1709 and the sli became working again.
Mention:everything detected well in Device manager,nvidia control panel,bios and etc
Thing I've tried
-Install the lastest driver from nvidia
