How to use sli

[yourking77]

So I need to order a bridge it should be here tommorrow, however I was wondering how it all works, if a game is not compatible will it just not run at all? Or will it just not make use of the second card? Anything I should know before hand?

This article should help out a bit. It is supposedly only usable in games that support it.

Game that are not supported will automatically run on only one card

Also waste of money to sli

Also not a single vr game support sli

Not all games are SLI but most well designed AAA games are suppoted. Performance increase is dedpendant upon the game. If the game does not support it one click in the Nvida panel disables it. Newer Cards use a newer adapter. You need good case cooling to keep two cards cool. A good power supply with headroom to support two cards. When it works it works well 20%+ improvement or more. It is not dead that is why SLI is on all the better boards.

I am a bit worried about cooling will have to keep a good eye on temps when my bridge gets here tommorrw.

That is nice to know that it will automaticall;y just use one card, was worried I woul;d keep having to play with teh bios once I get it all set up.

However wouldnt fo4 use sli in vr? that was one of teh main points of me getting it.

I probably did waste money however I have a computer that for the most part not many people can match, two 1080ti's is pretty ♥♥♥♥♥♥♥ impressive I think, I worked hard to save up for this badass rig, and I worked pretty damn hard putting it all together too XD

Most games will simply only use one card if they don't support sli, some however will require you to disable the second card to run best, you do this via nvidia control panel for the individual game.

Some games that won't support sli can be made to use sli by building a custom sli profile in nvidia inspector.
Some games will run worse with sli than on a single card and pretty much anything built on the unreal engine (which is nearly half the damn games released these days) won't use sli, it's a limitation of the engine.

I hope you bought the correct length bridge :)

But these issues were all covered in your last post, I even directly answered this very question.

SLi doesn't make much sense and sits squarely in the enthusiasts realm these days, so I hope you can learn to get the most out of your new rig.

With that said I guess I'll welcome you to the sli club.

hell even if it dont work for many games you can atleast still get some damn impressive numbers in 3D Mark lol

I have two Asus ROG Strix 1080Ti OC, and for me personally is was more for the aesthetics than anything else, i did not like the look of my rig with just one card, too much of a space between GPU and the PSU..

The bridge said it was for slots 1 and 4, there are two slots between my gpu pcie slots so i am assuming I got teh correct length one

Nope. There are so few VR games that use SLI it;s not even worth mentioning. Here's the list though:

The problem (when it boils down to it) is that SLI in VR is a niche market within a niche market. If a million headsets have sold, there might only be 30k's worth of people capable of running titles in VR currently. Its time spent optomising for SLI that so few will benefit from.

It's not just VR titles suffering either. Even desktop game devs are shying away from it now as AMD dropped crossfire last year (the AMD equivlent), Nvidia have dont the bare amount to support the system and market prices for GFX cards got stupid because of bit coin mining (making the whole fix cost prohibative to people).

Maybe it will change in the future and this is all to little to late for you but for anyone else reading this....just buy the single best card you can for the moment. Unless you are running a multiple screen set up, you probably wont gain much from SLI.

I dont car that i wasted money, if I wasted money. I think it was worth it for even the smallest benefit, I do want teh primax 8k though and for that it recomend two 1080ti cards.

SLI just isn't worth it. Just use one card and maybe return the other.
