no you don't need to do anything.

Right now so far ao good. The real problem was windows . And all the new feature i think he didnt liked i didnt wanted of skme apps haha. But the problem was that i tought that it would be good to reinstall the driver etc. So i give a try amn when i wanted to click on active sli adjuste 3d performance. It was telling me to close internet. Skype. Some apps like that , that i never even used before. It bugged all my download etc. So i had to let windows install his own driver, then click update driver in device manager, and then i restart again. But no luck . Still saying that i overclock failed etc so it was annoying.
Once you update the drived in device manager. Go get gforce experience and install it. It will update itself but it took a lil while . Like almost if he was in trouble. During the procees. Once this done go try enable sli. It should work. During this time windows was tryng to update something but i dont know what and lools like the system was on loop.
Now i did restart it. 2 times already and is still good . I tried to updatd anything and looks good. Sli is enable it even asked to optimise more after gforce experience finished. Il give a try to timespy 3dmark will see.

yep i dont have a single error in event viewer. very nice!!
