Random reboots, error reporting calls it BSOD, next gen hardware

Darn. I thought you had already done that. But it's great to know that fixed it for you.

You're welcome. The drivers are actually installed by Nvidia, but, all you are really doing is getting rid of all the older drivers, getting Nvidia to do a clean install and get rid of the remnants of older drivers and not installing anything that you don't need. One example is Nvidia installs an HDMI driver, which very few people use. Most motherboards have Realtek sound systems and include HDMI divers. Nvidia HDMI drivers can have a conflict with Realtek drivers. So, you are taking that possibility away. But, for whatever reason, it works. That's the way I install drivers every time and never have driver problems.

If you would, whenever you think your problem is solved, please mark this thread as solved. I'm glad everything is working for you.

I noticed it was marked solved after I made that post. Guess I should pay more attention. The biggest thing about video card drivers, is removing as much as possible of the older driver before installing the new one. They even make programs to do that. 2 sets of almost any driver can cause conflicts, but it is most important with video cards, they can be very problematic as they are pretty complicated beasts. The HDMI driver, was just an example, and why Nvidia decided to add that is beyond me. But still it was only an example. The clean install thing is the trick. as much as possible, that tutorial kind of forces a clean install. Use it. Once you get used to it, it will be very simple and very quick. It works pretty well, especially for people who tend to have driver problems. That's why I use it and why I wrote it, to try to help people having driver problems.

Are you sure you set up the SLI correctly? And are you sure you have the cards in the correct slots recommended by Asus Manual? if not, please read this and see if everything is set up right Introduction to SLI Technology | GeForce

Failing that, I would break the SLI and try 1 card at a time by removing one and putting it through all the stress tests and making sure it is not the card. Do it in both slots And see what kind of performance and reaction you get out of it. Next, take that card out and try the other card in both slots Testing the crap out of it. This will test your motherboard slots as well as the cards.

We are reasonably sure that it Is not a driver problem and if you read the article and set up SLI correctly it is not the set up. The only thing I know is that if the SLI set up is right, the Drivers install is right, the only thing left is one card is defective, the motherboard slots are not right or the PSU is not putting out what is required to run SLI. As I see it, those are the only options left for us. If you like, I will ask someone more experienced with SLI to come here and take a look.

High BotenRedWolf,

I've just quickly skimmed over your thread, Am I right in thinking it's just Watch Dogs you're having the trouble with now? I've seen some of the same transparency/artifacting you mentioned while playing it myself but only the once. There are a few settings in the game that cause a lot of stutter and lag, I also found that running the Uplay launcher as admin stopped a lot of the game lock ups.
Are you running the game across all 3 screens? if so at what settings? Watch dogs is a killer of Vram and puts a strain on my cards..
