[SOLVED] SLI On Motherboard

[PvtJacobClutch]

Good Morning or Good Evening,

So in my build, built my self my first one about 6-9 months ago, I have a Zotac Gaming RTX 2070 Super and I really want to add another to increase my gaming performance at higher graphics.
I have a Asus Tuf Gaming x570 Plus (wifi) mother board, it does not support SLI, can I still add another GPU? Will it work? will it even do anything. I do have a AMD Rysen 9 3900X in it and I know its supposed to make the mother board better but I dont know where I should go with the rest of this process.

SLI requires two x16 pcie slots.
You can do crossfire with two x8 slots.

So the blurb on your motherboard will tell you what you can and can't do and what pcie slots to use.

OK so there are 2 x16 slots but one of them is "x4 mode" and the other "x16 mode", and the box or manual does not say SLI supported

Hi Jacob and welcome to the Forum

As far as I know the X570 chipset supports SLI however imho SLI is redundant and not worth the hassle.
Nvidia do not offer a great deal of support anymore either.
A reason for not support would be (SLI requires at least 8x) and your second slot is 4x

You can having two PCIe slots, add another card for dedicated PhysX.
PhysX running on a dedicated GPU allows offloading the PhysX processing from the GPU used for standard graphics rendering, resulting in an optimal usage of processing capabilities in a system.

SLi is nearly dead. Game support has been in decline for years and the games that support it often have disappointing performance gains. I saw a review a while back and of game that supported sli the average improvement was about 30%. SLi can also suffer micro stuttering. I’d recommend ignoring SLi, if you want more performance sell your 2070 and look at the 3060/3070 when they release.

There is no mention of SLi support on your motherboard, only crossfire. I would say your motherboard does not support SLi . See multi gpu support https://www.asus.com/uk/Motherboards/TUF-GAMING-X570-PLUS-WI-FI/specifications/

I had no idea, thats why I could not find any info other than stuff based of the 1080s, ok so if I do that it will make my game play alot better?

Also what is PhysX?

Ok Thank you so much!

That is the more thorough explanation. Have you seen ingame movement where two objects collide say a bunch of Balls or a flag blowing in the wind. Well that is Physx which takes a lot of calculation for the GPU.
The calculations are offloaded to the dedicated card.

Thank you again!

Usually you'll find that you have more NVMe drive slots if you can do SLI. That's where the pcie lanes usually go.

I have a dedicated card for Physx and yes performance is improved but only in games or demos that have PhysX.
